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).

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.

Systems, methods, and apparatus are provided for preventing and treating pressure ulcers in bedfast patients. The invention includes providing a non-powered mattress having a first zone adapted to conform to a first body part and a second zone adapted to provide support to a second body part, and off-loading interface pressure on the first body part to the second body part by dynamically increasing the support provided to the second body part by the second zone based on a weight of the first body part on the first zone. The off-loading of interface pressure from the first body part to the second body part equalizes blood oxygen saturation in tissue of the first and second body parts. Numerous additional aspects are disclosed.

A multi-zone mattress comprising a top layer, an intermediate layer and a bottom layer disposed in substantially parallel relationship relative to each other including a first plurality of zones each having a first firmness profile to support a person thereon separated by a second plurality of zones each having a second firmness profile less than the firmness of the first firmness profile of the first plurality of zones, the first plurality of zones and the second plurality of zones each cooperatively formed by corresponding sections of the top layer, intermediate layer and bottom layer disposed in substantially parallel alignment relative to each other.

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.

A mattress with two layers. The upper layer includes a flat top surface, and the lower layer has a flat bottom surface. A contoured surface defines the lower boundary of the upper layer and the upper boundary of the lower layer. The contour generally matches the curvature of an individual's body when recumbent. More specifically, the bottom surface of the upper layer is shaped to match the curvature of individual's body, while the top surface of the lower layer is complementary to the curvature of the individual's body. When so arranged, the bottom surface of the top layer and top surface of the bottom layer are complementary to one another, and the top layer may be nested upon the bottom layer.

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 ventilated adjustable firmness bed designed to allow a user to manually change the firmness of their bed. A ventilated adjustable firmness bed includes a multilayered mattress and a uniform mattress, wherein the multilayered mattress and uniform mattress each have a different firmness. A cover is designed to enclose both the multilayered mattress and the uniform mattress, with a fastener designed to secure the multilayered mattress and the uniform mattress within the cover. The multilayered mattress has a plurality of apertures designed to provide ventilation and has one or more layers, each of a different firmness and extending the full width and length of the multilayered mattress such that each layer is flush against one another. The uniform mattress has a plurality of slots along an upper surface. In this way, a user is able to manually adjust the firmness of the bed through vertical alignment of the mattresses.

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.

A cushioning device includes a machine-washable polyurethan viscoelastic foam and a cavity for receiving a filler.
