20. The mattress cover according to claim 19, wherein the inner layer has a weight portion of cover fabric ranging from 25% to 30%.

21. The mattress cover according to claim 12, wherein the middle layer has a weight portion of cover fabric ranging from 10% to 20%.

22. The mattress cover according to claim 21, wherein the middle layer has a weight portion of cover fabric ranging from 15% to 20%.

23. The mattress cover according to claim 11, wherein the cover fabric has a weight ranging from 250 g/m.sup.2 to 300 g/m.sup.2.

24. The mattress cover according to claim 11, wherein the cover fabric is the same on all faces.

25. The mattress cover according to claim 11, wherein said cover comprises a fastener that is peripheral at least in part and that is openable in order to insert or remove a mattress core.

26. The mattress cover according to claim 25, wherein the fastener is a zip fastener.

Description

[0031] Further advantages and advantageous developments of the invention can be found in the claims and in the embodiment that is described schematically and with reference to the drawings.

[0032] In the drawings:

[0033] FIG. 1 is a schematic perspective view of a mattress cover that is designed according to the invention and has been put onto a mattress core;

[0034] FIG. 2 is a highly simplified plan view of a detail of an outer face of the mattress cover; and

[0035] FIG. 3 is a schematic cross-sectional view through a region of a cover fabric of the mattress cover.

[0036] With reference to FIG. 1, a mattress cover 1 can be seen in a state when stretched over a mattress core 2, the mattress cover 1 forming, for a user sleeping thereon, a first lying surface on an upper face 3 and a second lying surface on an opposing lower face 4.

[0037] The mattress cover 1 is formed by the same cover fabric 5 all the way around, lateral transverse surfaces 6 and longitudinal surfaces 7 also transitioning seamlessly, in the present case, into the upper face 6 and lower face 7.

[0038] Deviating therefrom, however, in other embodiments the surfaces of the cover fabric 5 may also be separated by stitched seams and a welting band may optionally also be provided.

[0039] In order to insert and remove the mattress core 2, a peripheral fastener 8 in the form of a zip fastener is sewn into the mattress cover 1 on the transverse surfaces 6 and longitudinal sides 7. In addition, a plurality of grips 9 for lifting the mattress core 2, encompassed by the mattress cover 1, are provided on the lateral longitudinal surfaces 7, just one of said grips or handles 9 being shown by way of example.

[0040] As can be seen in a detail X in FIG. 1, which detail represents the entire surface of the mattress cover 1, and in FIG. 2 and FIG. 3, the cover fabric 5 is formed having a weft-knitted 3D spacer fabric 10 as far as the outer face 11 thereof, the cover fabric 5 having a honeycombed mesh structure having a regular, delicate arrangement of outwardly open recesses 12. In this case, the recesses 12 preferably have an oval cross section towards the outside, which cross section can be approximately 2 mm to 4 mm wide and approximately 3 mm to 5 mm long when unstretched. The widths of the weft-knitted spacer fabric 10 material projections 13 located between the mutually offset and regular recesses 12 are at least approximately the same.

[0041] In the present case, the cover fabric 5 of the mattress cover 1 is designed as a three-layer weft-knitted 3D spacer fabric comprising an upper layer 14 that forms the outer face 11 and is formed of a textured, twisted polyester multifilament yarn; a middle layer 15 that is made of a coarse polyester multifilament yarn, is knitted to the upper layer 14, jointly forms the weft-knitted spacer fabric 10 and is used as a filling material; and a layer of smooth polyester yarn that is knitted to the upper layer 14 and the middle layer 15 and forms an inner layer 16.

[0042] In this case, the upper layer 14 has a finely knitted structure 17 on the outer face 11 thereof, which structure provides the surface with a soft feel.

[0043] With regard to the thickness, in the advantageous embodiment shown, the upper layer 14 is dimensioned so as to occupy at least 70% to 80% of the total thickness of the cover fabric 5, in order make use, as far as possible, of the microclimatic advantages of the weft-knitted spacer fabric 10.

[0044] In order to allow as much air circulation as possible and optimal moisture removal at the outer face, the honeycombed recesses 12 extend substantially over the thickness of the upper layer 14 and of the middle layer 15 until adjacent to the lower layer 16 such that, as a result of the recesses 12, the cover fabric is very flexible and stretchable in the width direction. The springiness in the height direction achieves a softness which can be defined, according to the desired degree of softness, by means of the filling material of the middle layer 14.

[0045] Of course, depending on the application, the cover fabric 5 can be produced using all known methods for weft-knitting spacer fabrics on circular knitting machines, and using all known finishing methods, such as a washing, bleaching and shrinking process following the knitting process.
