A custom mattress having an upper layer and a lower layer. The upper layer has two or more segments arranged such that a first segment is positioned at a head of the mattress and a second segment is positioned adjacent the first segment at a first transition point. The lower layer has two or more segments arranged such that a third segment is positioned at the head of the mattress and a fourth segment is positioned adjacent the third segment at a second transition point that is offset a distance from the first transition point, the distance being measured along a longitudinal axis of the mattress. Each of the segments have different densities.

Detachable and reversible mattress ticking assembly may be constructed so as to provide consumers the ability self-modify the orientation of the reversible mattress ticking so as to enjoy dissimilar performance attributes that the reversible ticking assembly or to merely extend the useful service life of the mattress ticking assembly when one side or the other becomes worn or aesthetically diminished.

The present disclosure relates to a breathable cushion. The cushion includes a thigh support portion, a hip support portion, and a waist and back support portion. The thigh support portion includes a plurality of thigh support structures each having an opening structure; the hip support portion includes a plurality of hip support structures each having an opening structure; and the waist and back support portion includes a plurality of waist and back support structures each having an opening structure. The area of the opening structures of the thigh support structures and/or the area of the opening structures of the waist and back support structures is greater than the area of the opening structures of the hip support structures. The cushion has the following advantages. The cushion has an ergonomic design and structure, and provides reasonable and reliable supports. In addition, the light-weight and highly comfortable cushion has good air permeability.

A cushioning module used to make various furniture such as mattresses, made of a matrix of cells, each cell made of typically a cuboid base supporting a typically cuboid top, made of a compressible and retractable material such as foam, which top has a smaller diameter than the base so that when said cells are tightly arranged, each top is apart from adjacent tops, enabling it to contract and retract spring like. Said matrix inside a bag which tightly embraces it from all sides and has an opening via which each cell can be removed and replaced. Pods can have a smoothing layer spread over said tops, means for fastening them together, carrying handle, stiffening pads along their lateral sides and a cover around their assembly. Cells can also be sacks filled with cotton, wool, dawn, foam bits or air which can be let out and re-filled.

Processes for personalizing a mattress or pillow for a consumer generally includes analyzing data identifying one or more target areas based on surface temperature and/or pressure on a consumer's existing mattress and additively manufacturing a lattice structure to address the one or more target areas so to provide support, pressure point relief, and/or a desired temperature modulation.

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.

A mattress includes a first, phase changeable component and a thermal management system adapted to control the temperature of the phase changeable component in order to change the firmness of the mattress. In one embodiment the phase changeable component includes two dimensional lattices separated from each other and a spring element extending between the lattices. Some embodiments of the mattress include an optional single phase component. The firmness can be made spatially and/or temporally uniform or nonuniform, and can be controlled based on one or more sensed parameters.

According to the present invention, in a plan view of a seat surface (10a), a plane area of a part surrounded by an inner edge (17a) of a rear part (17) in a left-right direction (X) and a contour (L) is larger than a plane area of a part sandwiched by an inner edge (18a) of a front part (18) in the left-right direction (X) and the contour (L) in the left-right direction (X). In addition, a part of a pair of left and right second synthetic resin materials forming a lower part having a maximum gap therebetween in the left-right direction (X) is positioned in a thigh rest part (14) and a part having a minimum gap is positioned in a hip rest part (15), and a maximum value (W1) of the gap between the pair of left and right second synthetic resin materials forming the lower part in the left-right direction (X) is two times or more a minimum value (W2) of the gap in the left-right direction (X).

Systems and apparatuses include a mattress assembly including a tub including vertically extending rails and a base that defines a base height that is two inches or less, the tub defining an interior cavity bound by the rails and the base, a plurality of non-laminated and rearrangeable foam layers positioned within the interior cavity to provide both support and comfort levels within the mattress assembly, and a cover system that includes a removable cover allowing selective access to the plurality of layers and the interior cavity and selectively compressing the plurality of layers within the tub.

A patient support apparatus is provided with selective stiffening features. The patient support apparatus may include a support substrate defining a patient support surface. The support substrate may include a magnetorheological material providing selective reinforcement support of at least a portion of the patient support surface to redistribute pressure about a surface of a patient. The magnetorheological material may include a distribution of ferromagnetic particles disposed within a polymeric material and exhibits a shape conforming, variable stiffness in response to exposure to a magnetic field. A controller may be provided and configured to create a correlation of patient specific data with an optimal stiffness or inflection force deflection (IFD) of the patient support surface, and generate a strength of the magnetic field based on the correlation.
