A bed defining a negative space to accommodate side sleepers and stomach sleepers by providing a space into which the user's arms and shoulders can extend. Channel pillows can be placed inside the negative space to provide support for the user's head while allowing the user's hands and shoulders to slide in between the channel pillow and the wall that define the negative space. The negative space is formed into a foundation having an upper torso region, a lower torso region, and a transition region therebetween. The transition region can comprise an angled wall. A cushion layer with a slanted wall is configured to cover the transition region and lower torso region of the foundation. An upper, comfort layer can be provided with a cutout that aligns with the negative space when placed on top of the foundation and cushion layer.

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.

Provided is an air-cushion block structure, and a mattress including the air-cushion block structure installed therein. The mattress of the present invention is provided with an air-cushion block structure which includes: an upper cushion having a first core hole vertically formed therein; and a lower cushion which has a second core hole vertically formed therein, and is disposed at a lower portion of the upper cushion. Accordingly, it is possible to stably transfer a weight of a user applied from an upper portion of the air-cushion block structure to a lower portion thereof, as well as, achieve a structure that stably supports the weight of the user by minimizing an occurrence of torsional deflection caused by the weight.

Mattresses, cushions, and body-support mats or pads are disclosed. Polymer(s) at least partially define a length, width and depth, the depth extending from an upper surface proximate to where a user rests to a lower surface opposite the upper surface. Voids in the polymer traverse at least a portion of the width. The plurality of voids are located at the lower surface and/or the upper surface and are defined by polymer walls and wall(s) of polymer walls define each polymer foot of polymer feet. A first region of a plurality of lower surface regions includes at least one foot of the plurality of polymer feet that has a first size. A second region of the plurality of lower surface regions includes at least one other foot having a second size. The at least one other foot spans a greater distance along the length than the at least one foot.

A symmetrical zoned foam mattress includes an upper foam layer with a wavy lower side and a lower foam layer with a wavy upper side. The lower layer has top, middle and bottom lateral valleys. The wavy lower side of the upper layer is glued to the wavy upper side of the lower layer. The top lateral valley has a minimum located within eighteen inches of the top head end of the lower layer. The bottom lateral valley has a minimum located within eighteen inches of the bottom foot end of the lower layer. A center plane intersects the lower foam layer at a minimum of the middle lateral valley. The minimum of each of the top and bottom lateral valleys is about fifteen inches from the end of the mattress regardless of whether the consumer chooses to use the top or bottom end as the head of the mattress.

A method for packaging a cushion includes coating a cushioning element with a powder while the cushioning element is in an expanded state and then compressing the cushion to a compressed state. As the cushioning element is compressed, the powder prevents surfaces of the cushioning element (e.g., surfaces of intersecting walls that define hollow buckling columns of a cushioning element formed from an elastomeric polymer extended with a plasticizer, etc.) from adhering to each other. The powder may allow the cushioning element to substantially return to its expanded state substantially immediately following removal of a compressive force from the cushioning element.

The present disclosure discloses a combination mattress, including a first layer and a second layer which has a smaller rigidity than that of the first layer and is stacked on the first layer, the thickness of the first region in the first layer corresponding to the shoulder of a human body is smaller than that of a second region corresponding to the waist of a human body the overall rigidity of the region corresponding to the shoulders of the human body in the combination mattress is smaller than the overall rigidity of the region corresponding to the waist of the human body.

A mattress having variable height and hardness is disclosed. The mattress comprises a base layer held by a mattress cover using an extendable attachment system. The mattress further comprises one or more top layers made of resilient material which are stacked on top of the base layer. Only friction between the material of the top layers limit the lateral or longitudinal movements of a layer with regard to another layer.

A mattress comprising a first layer comprising at least one trench extending laterally from a first side of the layer to an opposite side of the layer; a plurality of support members disposed in each trench; and a second layer disposed over at least the at least one trench. Another mattress comprising a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer; a plurality of support members disposed in each channel; and a second layer encompassing the first layer. A mattress assembly comprising one of the mattresses and a mattress foundation.

A mattress comprising a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer, and a plurality of tubular foam springs disposed in each channel. A mattress assembly comprising the mattress and a mattress foundation.
