It is disclosed a foam mattress having an adjustable mattress core for adjusting and customizing its firmness. The foam mattress has a foam base having an upper surface defining a top recess; and a plurality of foam inserts each configured to be disposed and assembled into the top recess to fill the top recess and form the mattress core with a continued upper surface of the mattress. The inserts are provided with at least two different firmness of the foam, preferably with three different firmness of the foam selected from firm, medium and soft, producing as such an inexpensive, novel consumer-adjustable mattress in which the consumer can change the firmness of the entire mattress and/or the firmness on either side of the bed to accommodate each sleeper and/or the firmness under certain “body zones” within the mattress for their own personalized comfort preference and to reduce tossing and turning.

A support element, for example a plate, a mattress, a pillow, a seating plane of a chair, of an armchair, a saddle for vehicles and the like, equipped with a resting surface for a user, includes at least one first layer in gel associated with at least one second layer of different material; such a first layer in gel and such a second layer, that are associated, are crossed by through openings that are suitable for the proper circulation of air from one side to the other of the support element, so as to allow the optimal transpiration and thermal regulation of the parts of the body of the user positioned resting on the support element itself.

A foam core for a mattress including a supporting layer for supporting the vertebral column, the supporting layer including an upper part and a lower part. Different body support regions are provided in the upper part along the longitudinal direction of the foam core, a plurality of the body support regions having at least one recess in the material of the foam core. At least one reserve region is provided in the lower part and has at least one recess in the material of the foam core. The foam core is formed such that the reserve region is not substantially deformed in case of a load on the upper part above the reserve region if the load is below a predetermined limit pressure, and that in case of a load above the predetermined limit pressure, the reserve region is deformed. A mattress having such a foam core is furthermore shown.

It is disclosed foam mattresses or toppers, and methods of using them, comprising a top surface defining lateral deflective areas thanks to structural modifications of the foam comprising a plurality of slots, grooves, voids or channels. The invention (mattresses, toppers or methods) allows controlling postural alignment while providing ultra-low mattress-body interface pressures for all body areas regardless of recumbent position. The method comprises the step of providing into a core section of the mattress a plurality of structural modifications comprising slots, and/or voids, to form transversal deflective areas into the mattress. The invention is preferably achieved by CNC (Computer Numerical Control) cutting the structural modifications (channels, slots and voids) into the mattress foam which support each area of the body. It is also disclosed mattresses or toppers in which foam inserts are kept or removed from the channels to modulate the deflections on one or both sides of the mattress.

A mattress made of natural latex foam has at least four layers. Each of the layers having a density that is different than the density of the adjacent layers. The mattress may also have on the first layer a plurality of magnets and infrared elements. The mattress may also have massage elements and/or a low frequency energy element between the second and third layers.

A mattress having of a center and a perimeter edge, including threads endowed with longitudinal cavities which, when glued or welded to each other, form a mattress capable of reducing costs and bringing significant improvements to the technological sector of mattresses, as well as making the mattress recyclable to form a new mattress, whose field of application pertains to the technological sector of mattresses.

A mattress assembly includes a base layer, a coil layer disposed over the base layer, an upper layer disposed over the coil layer, and an elastomeric cushioning element disposed over the upper layer. The coil layer may include a plurality of pocketed coils. Furthermore, the elastomeric cushioning element may have a thickness within a range of about 2.0 inches to about 4.5 inches. Furthermore, the elastomeric cushioning element may form between about 15.0% and about 32.0% of an overall thickness of the mattress assembly. A method of forming a mattress assembly includes disposing a coil layer over a base layer, disposing an upper layer over the coil layer, disposing an elastomeric cushioning element over the upper layer, and disposing an outer covering over at least the upper layer.

The subject invention is a device intended for use where support or restriction of motion of a body part is desired. The subject of the present invention is the formation of a network of lattice intrusions into the matrix of the device so that elements of the lattice can be removed to form a depression in the matrix of the device that conforms to the anatomy of the region that is being supported and positioned while offloading pressure.

A mattress assembly generally includes an orthotic layer generated from a deformation map associated with a particular end user and process of manufacturing he mattress assembly. The orthotic layer is rigid and flexible and minimizes pressure points relative the mattress assembly without the orthotic layer.

The invention relates to a mattress comprising at least one layer (31) having a multiplicity of elastic elevations. Said elastic elevations together form at least one supporting surface for the user of the mattress.

According to the invention, the elastic elevations are designed, or arranged, such that an uneven supporting surface is formed.

At least two types of elastic elevations with different elasticity are preferably provided. The elastic elevations are formed in particular on elastic bodies (21, 22, 23, 24), wherein each elastic elevation can be formed on a respective elastic body.
