Embodiments of a mattress ventilation foundation and sleep system are disclosed. Foundation embodiments typically may be configured to provide ventilation to a supported mattress, for example through an upper surface of the foundation allowing airflow therethrough. Sleep system embodiments typically have a mattress (which might be a ventilation mattress) atop such a ventilation foundation, with airflow therebetween.

Resilient cores preferably for inflatable bodies having resilient slabs that define a plurality of generally columnar holes or resilient arrays of generally columnar solids, methods for making such slabs and arrays, and articles incorporating the same wherein the cores further include thermal transmission mitigation means for improving a core's resistance to heat transfer beyond the core's innate insulative properties. Non-exclusive and non-exhaustive examples of such thermal transmission mitigation means in slab core embodiments include consideration to hole or bore geometric cross section, frequency, pattern and orientation, the introduction of a thermal barrier at or within at least some holes or bores, and/or slab material selection/treatment. Non-exclusive and non-exhaustive examples of such thermal transmission mitigation means in array core embodiments include consideration to the geometric cross section, frequency (density), pattern and orientation of the solids, the introduction of thermal barriers within inter-solid spaces and/or solid material selection treatment.

A cushion includes a cushioning element and a coating provided on a surface of the cushioning element. The cushioning element comprises an elastomeric material forming a plurality of intersecting buckling walls defining a plurality of hollow columns in an expanded form. The elastomeric material comprises an elastomeric polymer and a plasticizer. The coating comprising an olefin powder formulated to hinder adhesion of the elastomeric material when the cushioning element is in a compressed form such that the plurality of intersecting buckling walls is pressed together. The cushioning element is configured to be compressed by a roll-packing machine into the compressed form and subsequently released from the compressed form to transform to the expanded form. Methods of forming the cushion include forming the cushioning element comprising an elastomeric material, coating a surface of the cushioning element with olefin powder, and compressing the cushioning element into a compressed form.

A patient support system includes a patient support apparatus and a support surface mounted on the patient support apparatus. The patient support apparatus is reconfigurable among a plurality of different configurations for supporting a patient on the support surface in a plurality of positions. The support surface is mounted on the patient support apparatus to move in response to reconfiguration of the patient support apparatus.

A cellular cushioning system includes cells or support units arranged in one or more stacked arrays. The cells are hollow chambers that resist deflection due to compressive forces, similar to compression springs. The arrays are attached to one or more intermedial binding layers. The intermedial binding layer(s) links the cells together while allowing the cells to deform independently of one another. An external load compresses one of the void cells within an independent compression range without significantly compressing at least one void cell adjacent the compressed void cell. The independent compression range is the displacement range of the compressed void cell that does not significantly affect the compression of adjacent void cells. If the void cell is compressed beyond the independent compression range, the intermedial binding layers may be deflected and/or the void cells adjacent the compressed void cell may be compressed.

Embodiments of a ventilated sleep system are disclosed, and typically may be configured to provide ventilation to a mattress, for example through an upper surface of a foundation allowing airflow therethrough. Typically, sleep system embodiments may include mattresses with foam layers with pinholes and a bottom cover allowing airflow therethrough, and some embodiments also include foam pillars. Such sleep system embodiments typically may have such a ventilation mattress atop such a ventilation foundation, with airflow therebetween.

This invention is a mattress core that is manufactured as a single unit. It is made up of individual cones that have different configurations resulting in different densities at different portions of the mattress. There are three main ways to accomplishing this goal: columns of different sizes and shapes, columns with different hole diameters, and columns with different density foam used to create them. A key advantage of this invention is that it is a single mattress made from a single mold, and does not require multiple parts to be put together.

A patient support system includes a scale system, an air system, and a lift system. The patient support system also includes a control system configured to graphically communicate information about the scale system, the air system, and the lift system to a user.

It is disclosed a foam mattress or topper to control a whole body alignment, comprising: a first foam section defining an upper surface, a lower surface, a longitudinal direction allowing for longitudinally receiving a user's body, and a plurality of mattress areas comprising: an upper body receiving area for supporting user's upper body and shoulders; a lower body receiving area for supporting user's lower body; and a middle body receiving area for supporting a user's hip; and a first lateral channel within the upper body receiving area and extending in a lateral direction normal to the longitudinal direction of the mattress, the first lateral channel thereby allowing the upper body receiving area above the first lateral channel to displace downward to provide pressure reduction and alignment for the shoulder of the user's body. These mattresses and toppers have an ultra-low pressure capable of preventing sleep disturbance caused by pressure.

Mattress assemblies include at least one layer or a portion thereof including a preformed flexible and liquid impermeable capsulate completely encapsulating a bulk blend of phase change materials. The bulk blend of phase change materials include a low phase change transition temperature material configured to transition between a solid and a liquid during use, and high phase change transition temperature material configured to maintain crystallinity during use. Also disclosed are processes for forming the microencapsulated blend of phase change materials.
