DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0168] FIG. 1a shows an exploded view of a base element 100 according to an exemplary embodiment. FIG. 1b shows an adjustment device 300 of the base element of FIG. 1a. FIG. 2 shows a top view of the base element 100 of FIG. 1a.

[0169] The base element 100 comprises a frame element 101a and a cover layer 101b. The base element 100 further comprises an adjustment device 300. The frame element 101a has a compartment 102, wherein the compartment 102 is formed and/or dimensioned such that the adjustment device 300 can be accommodated and/or integrated in the compartment 102. Thus, the adjustment device 300 is at least partially received in the compartment 102.

[0170] The cover layer 101b of the base element is arranged on the frame element 101a. The frame element 101a may be formed partially or entirely of foam. Similarly, the cover layer 101b may be formed partially or entirely of foam. However, other materials are conceivable.

[0171] The cover layer 101b may optionally include a cutout 114, which may be formed to provide space for mounting/dismounting one or more components of the adjustment device 300.

[0172] The adjustment device 300, which is configured for deforming or adjusting the base element 100 and/or a mattress 202 placed thereon, comprises one or more drives 108, 108, for example two electric motors, and at least two rails 104, 104, which are arranged substantially parallel to each other and are connected to each other via at least one cross strut 103. Each of the rails 104, 104 thereby extends substantially parallel to a longitudinal axis 107 of the base element 100 and the at least one cross strut 103 extends substantially parallel to a transverse axis 109 of the base element 100.

[0173] Each of the rails 104, 104 comprises, by way of example, three rail elements 105a, 106b, 105c, which are arranged one behind the other in the longitudinal direction of each rail 104, 104 and/or parallel to the longitudinal direction 107. The rail elements 105a, 105b and 105b and 105c are each movably coupled to one another at their ends via a joint 106, so that the rail elements 105a, 105b and 105b and 105c can be pivoted about an axis parallel to the transverse axis 109 via the joints 106.

[0174] In the example of FIGS. 1a, 1b, and 2, the base element 100 or adjustment device comprises two drives 108, 108 and two drive mechanisms 115, 115. Each drive mechanism may comprise one or more pulley mechanisms and/or gear mechanisms, which may be at least partially arranged and/or integrated in one or more rail elements 105a-105c. Further, the adjustment device comprises two crossbars 103, 103, each of which may be associated with a drive mechanism 115, 115.

[0175] A shaft 135 may be arranged in each of the cross struts 103, 103 and coupled to one of the drives 108, 108. Alternatively, the cross struts 103, 103 can each form a shaft 135.

[0176] The drives 108, 108 are thereby arranged on one of the two rails 104 and can actuate the drive mechanism located in the rail elements of this rail, for example a cable pull mechanism and/or a gear mechanism. The rotation of the respective drive 108, 108 can be transmitted to and actuate the oppositely arranged rail 104 and the drive mechanism located in the rail elements of this rail, such as a cable pull mechanism and/or a gear mechanism, via the associated shaft 135 or cross strut 103, 103. In this way, portions 117a, 117b, 117c arranged between the rail elements 105a-105c opposing each other in pairs in the transverse direction 109 can be displaced, pivoted and/or tilted relative to each other.

[0177] To extend the rails 104, 104 in the longitudinal direction 107, a longitudinal support strut 302 is arranged at each end of each rail element 105a, 105c, such as at each head end and/or foot end of each rail 104, 104, of the base element 100, which are spaced apart and coupled to each other via one or more transverse support struts 110 in the transverse direction 109. On the one hand, the areas 117a and 117c can thus be enlarged, a stability of the adjustment device 300 can be increased and the adjustment device 300 can withstand increased loads. In addition to the areas 117a-117c, areas extending beyond the front ends, head ends, and/or foot ends of the adjustment device 300 can also be individually displaced. Thus, in the example of FIGS. 1a, 1b, and 2, at least three, four, or five differently and individually adjustable regions may be created. More or fewer areas may also be provided.

[0178] The adjustment device 300 further comprises a control circuitry 310 configured to control the adjustment device 300 and/or one or more drives 108, 108. For example, the control circuitry 310 can be used to control a direction of rotation, a speed of rotation, or the like. This can be done via a suitable control signal.

[0179] The control circuitry 310 further comprises an interface 112 coupled to a user interface 122 via a wired connection. The control unit 122 may comprise a user interface, such as a display, buttons, or the like, for controlling the control circuitry and/or the adjustment device 300. Alternatively or additionally, the control circuitry 300 has a wireless interface 312 for communicating with a receiver 120, such as a smartphone, tablet, PC, notebook, server, or the like, as shown in FIG. 2.

[0180] Further, the base element 100 includes an energy storage device 315, such as a battery or accumulator, for supplying electrical energy to the adjustment device 300. The energy storage device 315 can be charged, for example, via a cable that can optionally be routed through the frame element 101a and/or the cover layer 101b. Inductive charging or other techniques are also conceivable.

[0181] Further, components of the adjustment device 300 may be configured to be at least partially waterproof.

[0182] FIG. 3 shows a base element 100 according to an exemplary embodiment. Unless otherwise described, the base element 100 of FIG. 3 comprises the same elements and features as the base element 100 of FIGS. 1a to 2.

[0183] The base element 100 of FIG. 3 further has a base cover 301 in which the frame element 101a, the cover layer 101b and/or the adjustment device 300 are at least partially, in particular completely, accommodated. The base cover 301 is configured in particular to prevent a mattress 202 placed on the base element 100 from slipping. In this regard, the base cover 301 may be made of any material and/or fabric, in particular natural fiber, synthetic fiber or a mixture thereof. Also, the base cover 301 may serve to protect the base element 100.

[0184] Optionally, the base cover may also be at least partially waterproof, for example on its bottom, sides, and/or top. In particular, the base cover 301 may be at least partially rubberized, coated, and/or provided with latex, for example, on its outer side, inner side, top side, and/or bottom side.

[0185] The base cover 301 may be at least partially formed from a rubber-like material. Alternatively or supplementally, the base cover 301 is at least partially rubberized. Alternatively or complementarily, the base cover 301 is at least partially formed of latex. In particular, an upper surface on which a mattress 202 may be placed and/or an outer surface of the base cover 301 may be at least partially rubberized, coated, and/or provided with latex to prevent slippage of a mattress 202.

[0186] The base cover 301 comprises an at least partially circumferential closure 303, in particular a zipper 303, to be opened and/or closed for inserting and/or removing the base element 100. Optionally, the (zipper) closure 303 may be at least partially waterproof.

[0187] The base cover 301 may further comprise one or more cable grommets 350, such as for passing a cable of the control circuitry 112 and/or the user interface 120. Optionally, the cable feedthrough 350 may be mechanically reinforced, such as with an eyelet. Further optionally, the cable feedthrough 350 may be configured to be sealed, may at least partially enclose the cable in a sealed manner, and/or may comprise a sealing element.

[0188] FIGS. 4 and 5 each show a reclining furniture 200 according to an exemplary embodiment.

[0189] The reclining furniture 200 comprises a base element 100 on which a mattress 202 having a first side 203 is arranged and/or laid. Opposite the first side 203, the mattress 202 forms a lying surface 205 for a user. The lying surface thereby faces a bottom surface 101 of the base element 100. The base element 100 of FIGS. 4 and 5 may be formed like the base element 100 of the figures described above.

[0190] The reclining furniture 200 further comprises at least one reclining furniture cover 204, which encloses the base element 100 and the mattress 202 at least partially, in particular completely. The reclining furniture cover 204 may thereby be formed as a mattress cover 204 as described with respect to FIGS. 6 to 8. Optionally, the reclining furniture cover 204 and/or mattress cover 294 may be at least partially coated, rubberized and/or provided with latex to prevent water from penetrating.

[0191] Alternatively or in addition to the mattress cover 204, a further reclining furniture cover 204 may also be provided in the form of an at least partially waterproof outer cover 204 which may at least partially, in particular completely, enclose the base element, the mattress and optionally the mattress cover.

[0192] Optionally, a further outer cover may also be provided which at least partially, in particular completely, encloses the outer cover 204. The further outer cover can be configured analogously to the mattress cover as described above and below. Optionally, the further outer cover can also be at least partially coated, rubberized and/or provided with latex in order to prevent the penetration of water.

[0193] One or more of the reclining furniture covers 204 may comprise an at least partially, in particular fully circumferential closure 206, such as a zipper, which may optionally be at least partially waterproof.

[0194] For transport, two or more transport handles 210, 210 may also be provided on each flank of the reclining furniture 200. These may be at least 2 to 10 cm wide or wider and/or at least 5 to 20 cm long or longer, for example to ensure high stability and high carrying comfort.

[0195] In FIG. 4, the reclining furniture 200 is shown in a horizontal position. In FIG. 5, on the other hand, the individual areas 117a-117c are adjusted and/or displaced by the adjustment device 300, so that a total of at least four lying areas 401, 402, 403, 404 on the reclining furniture 200 or the lying surface 205 are arranged and/or positioned differently relative to one another. The user can individually change, adjust and/or adapt the individual areas or reclining areas via one of the operating devices 120, 122.

[0196] FIG. 6 shows a perspective view of a mattress cover 204 of a reclining furniture 200 according to an exemplary embodiment. FIG. 7 shows a highly simplified sectional top view of an outer side of the mattress cover 204 of FIG. 6. FIG. 8 shows a sectional schematic cross-sectional view through a cover fabric of the mattress cover 204 of FIGS. 6 and 7.

[0197] Referring to FIG. 6, an exemplary mattress cover 204 or mattress cover 204 is shown in a state stretched over a mattress 202 and a base element 100, wherein the cover 204 forms a first reclining surface on an upper surface 205 and optionally forms a second reclining surface for a user on an opposite lower surface 101.

[0198] The mattress cover 204 is formed circumferentially from the same cover fabric 5, whereby lateral transverse surfaces 6 and longitudinal surfaces 7 also merge, optionally seamlessly, into the upper side 6 and lower side 7. Deviating from this, however, in other embodiments, a separation of the surfaces of the cover fabric 5 can also be provided by seams and, optionally, a welting tape.

[0199] A circumferential closure 206 in the form of a zipper is sewn into the mattress cover 204 (or mattress cover 204) at the transverse surfaces 6 and longitudinal sides 7 for inserting and removing the mattress cover 202 and/or the base element 100. In addition, a plurality of handles 210 are provided on the lateral longitudinal surfaces 7 for lifting the base element 100 and/or the mattress 2020 encircled by the mattress cover 202 (or mattress cover 2), of which only one handle 210 is shown by way of example.

[0200] As can be seen in a section X in FIG. 6, which is representative of the entire surface of the mattress cover 204 (or mattress cover 204), and in FIGS. 7 and 8, the cover fabric 5 is formed with a weft-knitted fabric 10, such as a 3D weft-knitted fabric, to its outer surface 11.

[0201] The cover fabric 5 comprises a honeycomb-like mesh structure with outwardly open recesses 12 in a regular, fine arrangement. In this respect, the recesses 12 preferably have a round, rounded, elliptical and/or oval cross-section towards the outside, which in the untensioned state may be dimensioned, for example, 2 mm to 4 mm in width and about 3 mm to 5 mm in length.

[0202] The material webs 13 of weft-knitted fabrics 10 located between the recesses 12, which are arranged offset and regular to each other, can be at least approximately equal in width.

[0203] The cover fabric 5 of the cover 1 is present as a two- or three-ply (or layer) weft-knitted fabrics with an upper ply 14 forming the outer side 11, an optional middle ply 15 forming the weft-knitted fabric 10 and knitted with the upper ply 14, and an inner or lower ply 16 knitted with the upper ply 14 and/or the optional middle ply 15.

[0204] The upper layer 14 may comprise a monofilament yarn, such as smooth monofilament yarn, or a multifilament yarn, such as textured twisted multifilament yarn. Similarly, the bottom layer 16 may also comprise a monofilament yarn, such as smooth monofilament yarn, or a multifilament yarn, such as textured twisted multifilament yarn. Similarly, the middle layer 15 may be formed at least in part of monofilament yarn or multifilament yarn.

[0205] One or more of the top layer 14, the middle layer 15, and the bottom layer 16 may further include natural fibers and/or be at least partially formed from natural fibers, as described above. The natural fibers may be, for example, animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, linen fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or a combination thereof. Such natural fibers may be characterized, for example, by increased sustainability, odor neutrality, skin compatibility, durability and/or robustness compared to synthetic fibers.

[0206] The upper layer 14 further comprises a fine knit structure 17 on the outer side 11, which gives the surface a soft feel.

[0207] With regard to thickness, the upper layer 14 in the advantageous embodiment shown is dimensioned in such a way that it occupies at least 70% to 80% of the total thickness of the cover fabric 5, in order to utilize the microclimatic advantages of the weft-knitted fabrics 10 to the greatest possible extent.

[0208] In order to allow the greatest possible air circulation and optimum moisture removal to the outer side 11, the honeycomb-like recesses 12 extend essentially through the thickness of the upper layer 14 and the middle layer 15 to adjacent to the lower layer 16, so that the cover fabric simultaneously exhibits a high degree of flexibility and stretchability in width due to the recesses 12. The elasticity in height results in softness, which can be defined by the filler of the middle layer 14 depending on the desired degree of softness.

[0209] It is understood that, depending on the application, the cover fabric 5 may be produced using any known spacer knitting process as well as any known finishing process, such as a washing, bleaching and shrinking process following the knitting process. Optionally, the mattress cover 204 may be at least partially coated, rubberized, and/or provided with latex to prevent water penetration.

[0210] FIGS. 9a to 9f each show parts of a mattress 202 of a reclining furniture 200 according to exemplary embodiments. FIG. 9a shows a top view of a first mattress element 2 of a mattress 202 of a reclining furniture 200. The mattress 202 of FIGS. 9a to 9f may be combined with any of the preceding aspects of the reclining furniture 200, or individual aspects may be interchanged. FIG. 9b schematically shows a cross-sectional view of the first mattress element 2 of FIG. 9a, wherein the first mattress element 2 is shown without transverse grooves in FIGS. 9a and 9b. FIG. 9c shows a side view of the first mattress element 2 of FIGS. 9a and 9b with multiple transverse grooves. FIG. 9d shows a top view of a second mattress element 3 according to an embodiment of the disclosure. FIG. 9e shows a cross-section of the second mattress element 3 of FIG. 9d without transverse grooves. FIG. 9f shows a mattress 202 or a combination mattress 202 of the reclining furniture 200 according to an embodiment of the disclosure. The mattress 202 of FIG. 9f thereby comprises the first mattress element 2 described with reference to FIGS. 9a to 9c and the second mattress element 3 described with reference to FIGS. 9d and 9e.

[0211] The first mattress element 2 comprises a first outer surface 21 and an oppositely arranged first contact surface 32. The first outer surface 21 is thereby formed as a first lying surface 21 for the user. The second mattress element 3 comprises a second outer surface 31 and an oppositely arranged second contact surface 32. The second outer surface 31 is thereby optionally formed as a second lying surface 31 for the user. The first and second mattress elements 2, 3 are stacked on top of each other such that the first and second contact surfaces 22, 32 are at least partially in contact with each other.

[0212] For ergonomic and comfortable accommodation of the user, the two mattress elements 2, 3 and/or the mattress 202 and/or the reclining furniture 200 each comprise a plurality of support regions 41, 42, 43, 44, 45. The support areas 41, 42, 43, 44, 45 may thereby comprise a head support area 41, a neck support area 42, a shoulder support area 43, a lordosis support area 44 and a pelvis support area 45.

[0213] The mattress 202 comprises a longitudinal direction x (107 in FIGS. 1a to 3) or longitudinal axis x that is parallel to a longitudinal side of the mattress 202, a transverse direction z (109 in FIGS. 1a to 3) or transverse axis z that is parallel to a transverse side of the mattress z, and a vertical axis y that is transverse and/or orthogonal to the longitudinal direction x and the transverse direction z. A length of the mattress 202 of the reclining furniture 200 is dimensioned in the longitudinal direction, a width of the mattress 202 is dimensioned in the transverse direction z, and a thickness or height of the mattress is dimensioned along the vertical axis y. The length of the mattress 202 may be greater than or equal to the width of the mattress 202. The first mattress element 2 and the second mattress element 3 may comprise identical or different heights and/or thicknesses. The x-direction may thereby run parallel to the longitudinal axis 107 of the base element 100 and/or the reclining furniture 200. Alternatively or additionally, the z-direction can run parallel to the transverse axis 109 of the base element 100 and/or the reclining furniture 200.

[0214] Furthermore, the mattress 202 of the reclining furniture 200 comprises a central transverse axis 5 and/or a central transverse plane 5, which runs parallel to the transverse direction z and is arranged centrally between two ends of the mattress 202 that are opposite one another in the longitudinal direction x. The central transverse axis 5 and/or the central transverse plane 5 separate the first mattress element 2 into a first half 2a and a second half 2b. The central transverse axis 5 and/or the central transverse plane 5 thereby separates the first mattress element 2 into a first half 2a and a second half 2b. Similarly, the central transverse plane 5 and/or the central transverse axis 5 separates the second mattress element 3 into a first half 3a and a second half 3b.

[0215] Each of the halves 2a, 2b, 3a, 3b of the first and second mattress elements 2, 3 thereby comprises the support areas 41, 42, 43, 44, 45. The support areas 41, 42, 43, 44, 45 are thereby arranged mirror-symmetrically to the central transverse axis 5. The individual support regions 41, 42, 43, 44, 45 can thereby differ from one another at least in part with regard to a degree of hardness, a hardness, a compression hardness and/or an elasticity. For example, the supporting regions 41, 42, 43, 44, 45 can at least partially comprise a profile, profiling and/or structuring that differs from one another, for example in the form of transverse grooves 51, 52, 53, 54 formed in the respective supporting regions 41, 42, 43, 44, 45. The transverse grooves 51, 52, 53, 54 can thereby be formed in the first and/or second outer surface 21, 31 and extend over the entire width of the mattress 200 in the transverse direction z. In order to adapt the hardness of the individual support areas 41, 42, 43, 44, 45, profiles and/or the transverse grooves 51, 52, 53, 54 in the respective support areas 41, 42, 43, 44, 45 may differ from one another in terms of their cross-section, their geometry, their shape, their number, their depth dimensioned along the vertical axis y and/or their thickness or size dimensioned along the longitudinal direction x.

[0216] As can be seen in FIG. 9c, the first mattress element 2 comprises a single first transverse groove 51 in each of the two halves 2a, 2b, which separates the head support area 41 from the neck support area 42. The first transverse groove 51 has a T-shaped cross-section.

[0217] Furthermore, the first mattress element 2 comprises in each of the two halves 2a, 2b in the shoulder support region 43 a total of five second transverse grooves 52, which each have a round, oval, elliptical and/or drop-shaped cross-section. A geometry, width, dimension, size, thickness and/or a diameter of the five second transverse grooves 52 in the shoulder support regions 43 of the two halves 2a, 2b of the first mattress element 2 are identical. The neck support regions 42 of the first mattress element 2 are separated by one of the second transverse grooves 52 from the shoulder support regions 43 respectively adjacent to the neck support regions 42. Likewise, the lordosis support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support region 43 by one of the second transverse grooves 52. Furthermore, the lordosis support areas 44 are each separated from the adjacent pelvic support areas 45 by a third transverse groove 53. A total of three third transverse grooves 53 are formed in the two pelvic support regions 45 adjacent to each other at the central transverse axis 5, each of which has a T-shaped and/or triangular cross-section. The three third transverse grooves 53 thereby comprise identical geometries, widths, dimensions, sizes, thicknesses and/or diameters. The middle one of the three third transverse grooves 53 can thereby run in the center transverse plane 5 and define a boundary between the first half 2a and the second half 2b.

[0218] As shown in FIG. 9f, at least one additional transverse groove 54 may be formed in each of the lordosis support regions 44, which may have a circular and/or oval cross-section, for example.

[0219] As can be seen in FIG. 9f, the first mattress element 2 has no profile, profiling and/or structuring on its first contact surface 22. In other words, the first contact surface 22 is configured to be completely flat. Optionally, however, a profile can also be formed on the first contact surface 22 at least in a partial area. Conceivable here are any cross-sectional profiles for transverse grooves, such as round, oval, elliptical, triangular, square, polygonal, trapezoidal or the like, as explained above and below.

[0220] As can be seen in FIG. 9f, the second mattress element 3 comprises a single first transverse groove 61 in each of the two halves 3a, 3b, which separates the head support area 41 from the neck support area 42. The first transverse groove 61 is thereby configured analogously to the first transverse groove 51 of the first mattress element 2 and has a T-shaped cross-section. Furthermore, the second mattress element 3 comprises a total of five second transverse grooves 62 in each of the two halves 3a, 3b in the shoulder support region 43, which each have a round, oval, elliptical and/or drop-shaped cross-section. The second transverse grooves 62 of the second mattress element 3 are thereby configured analogously to the second transverse grooves 52 of the first mattress element, but a width, dimension, size, thickness and/or diameter of the five second transverse grooves 62 in the shoulder support regions 43 of the two halves 3a, 3b of the second mattress element 3 continuously decrease in the direction of the central transverse axis 5. The neck support regions 42 of the second mattress element 3 are separated from the shoulder support regions 43 respectively adjacent to the neck support regions 42 by one of the second transverse grooves 62. Similarly, the lordosis support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support region 43 by one of the second transverse grooves 62. Furthermore, the lordosis support regions 44 are each separated from the adjacent pelvic support regions 45 by a third transverse groove 63. A total of three third transverse grooves 63 are formed in the two pelvic support regions 45 adjacent to one another at the central transverse axis 5, which are configured analogously to the transverse grooves 53 of the first mattress element 2 and which each have a T-shaped and/or triangular cross section. The three third transverse grooves 63 thereby comprise identical geometries, widths, dimensions, sizes, thicknesses and/or diameters. The middle one of the three third transverse grooves 63 can thereby run in the center transverse plane 5 and define a boundary between the first half 3a and the second half 3b. Furthermore, analogous to the further transverse groove 54 of the first mattress element, at least one further transverse groove 64 may be formed in each of the lordosis support regions 44 of the second mattress element 3, which may, for example, have a round and/or oval cross-section.

[0221] The transverse grooves 61, 62, 63, 64 of the second mattress element 3 are arranged opposite the transverse grooves 51, 52, 53, 54 of the first mattress element 2 and formed on the second outer surface 32 of the second mattress element 3. Furthermore, the two halves 2a, 2b of the first mattress element 2 and the two halves 3a, 3b of the second mattress element 3 are configured to be completely mirror-symmetrical with respect to the central transverse axis 5 or central transverse plane 5.

[0222] As shown in FIG. 9f, the second mattress element 3 comprises a profile 33 at its second contact surface 32, which profile comprises a plurality of transverse grooves 34. The transverse grooves 34 are exemplarily shown with a rectangular cross-section. Any other cross-sections are conceivable.

[0223] Also, the profile 33 may be wave-shaped with multiple wave crests and wave troughs. Alternatively or additionally, the profile 33 or another profile may be introduced in the contact surface 22 of the first mattress element 2. Also, profiles and/or transverse grooves may be introduced into both contact surfaces, which may at least partially interlock.

[0224] Exemplary transverse grooves for the first outer surface, the second outer surface, the first contact surface and/or the second contact surface are shown in the following figures.

[0225] FIGS. 10 to 13 each show exemplary transverse grooves of a mattress 202 of a reclining furniture according to an exemplary embodiment. In particular, longitudinal sections through the respective mattress 202 are shown.

[0226] The mattress 202 of FIG. 10 has a total of three parts, comprising three mattress elements 2, 3, 3. In contrast, the mattresses 202 of FIGS. 11 to 13 comprise only two mattress elements 2, 3. However, more or fewer mattress elements can be provided as desired.

[0227] The transverse grooves and/or profiles shown in FIGS. 10 to 13 are arranged only schematically and exemplarily on the contact or outer surfaces of the mattress elements 2, 3, 3 shown there. However, the transverse grooves and/or profiles may also be arranged on any other surfaces of the mattress 202.

[0228] In the example in FIG. 10, the first mattress element 2 does not comprise a profile or transverse grooves. The second mattress element 3 comprises trapezoidal transverse grooves 500 on the contact surface 33 and rectangular transverse grooves 600 on a side or surface opposite this contact surface 33, which are recessed and/or introduced into the second mattress element 3 at a distance from this surface. A further mattress element 3 without profile forms the further outer surface of the mattress 202.

[0229] In the example of FIG. 11, the first mattress element 2 comprises transverse grooves 500 with a round cross-section on the outer surface 21 and transverse grooves 550 with a rectangular, trapezoidal or triangular cross-section on the contact surface 22. The second mattress element 3 has transverse grooves 600 with a round cross-section only on the outer surface 31 and the contact surface 32 has no profile.

[0230] In FIG. 12, the first mattress element 2 comprises bean-shaped transverse grooves 500 which are introduced into the first mattress element via incisions 501 from the first contact surface 21 such that the transverse grooves 500 are arranged closer to the first outer surface 21 of the first mattress element 2 than to the first contact surface 22 of the first mattress element 2. Similar transverse grooves 600 with incisions 601 are introduced into the second mattress element 3 via the second contact surface 32. In this regard, the transverse grooves 600 are shaped in a boomerang shape, a coat hanger shape, and/or a triangular shape. Further, additional transverse grooves 603 having a circular cross-section are introduced in the second mattress element 3. The second outer surface 31 of the second mattress element 3 has no profile.

[0231] In the example shown in FIG. 13, the first mattress element 2 and the second mattress element 3 have profiles and/or transverse grooves 500, 600 corresponding to one another on their contact surfaces 22, 32, which at least partially interlock in a tooth-like manner. The outer surfaces 21, 31 of the two mattress elements 2, 3 have no profiles.

It should further be noted that features described with reference to any of the above exemplary embodiments may also be used in combination with other features of other exemplary embodiments described above.
