A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

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.

Disclosed are patient positioning systems that support a patient in the prone position. A patient positioning system includes a chest bolster and one or more head supports selectively attachable to the chest bolster. The chest bolster elevates the patient's thorax and provides for gentle cervical flexion, while the one or more head supports can be attached to the chest bolster in different configurations to support the patient in a face down position or with the head turned laterally.

A hybrid seating cushion made up of a cushion base and a cushion insert. The cushion base has a seating surface in which a void in or extending through the cushion base is formed. A cushion insert such as an air bladder or fluid sack is positioned within the void. A lip or upper surface around an opening in the void overhangs at least a portion of the cushion insert, thereby minimizing the size and corresponding negative effects of a transition area where the base and the insert overlap.

A mattress combined with a sound vibration module and air fibers, and an operating method therefor. An air mattress to which air fibers are applied comprises a sound vibration module comprising a speaker, a tactile transducer, a controller, and an amplifier, the sound vibration module being manipulated to generate low-frequency vibration through the conversion of an input sound source into vibration or sound after being amplified, and at the same time emit same as sound. While sound vibration stimuli are applied to the skin through the sound vibration module, contact pressure is distributed on the air mattress to which air fibers are applied, and a static pressure state can be maintained as a fluctuating pressure state. Moreover, the effect of improving muscle strength by healing of muscle cells, blood flow improvement, and low-frequency vibration can be realized through vibration stimulation, to thereby stably prevent the occurrence of bedsore.

Modular mattress systems and methods are described. For example, a modular mattress can include a fabric cover configured to surround at least two foam layers. The fabric cover can include an opening to allow access to an interior region of the fabric cover. The mattress can include a first foam layer positioned within the interior region of the fabric cover, and an encasement layer positioned below the first foam layer. The encasement layer can include a recess configured to receive one or more modular support sections. The mattress can also include a plurality of modular support components received within the recess of the encasement.

A support cushion liner includes a liner body having a cavity disposed between an outer layer and an inner layer and a plurality of artificial muscles disposed in the cavity of the liner body. Each of the plurality of artificial muscles include a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair includes a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region thereby applying pressure to the outer layer of the liner body.

A device for elevating the legs and feet of a supine patient is formed by a unitary body having a top surface and a bottom surface, a front edge, a rear edge and two opposing side edges. Two open channels extending from the front edge to the rear edge are formed in the top surface and are configured to accommodate the lower legs or feet of the patient. The channels are separated by a divider. The channels are sloped upward from rear to front, so that the feet are elevated the most. In use, the patient places both of their lower legs into the channels, with the feet extending beyond the front edge of the device. The elevation of the device prevents the feet from touching the supporting surface.

A three-dimensional net-like structure is provided that has a soft cushioning property and less variations of hardness and is less expensive. The three-dimensional net-like structure is made from a thermoplastic resin including a mixture of a polypropylene copolymer (a) and a polypropylene copolymer (b) and has a spring structure formed by bonding continuous filaments partly in random in loops. The polypropylene copolymer (a) has a flexural modulus that is different from a flexural modulus of the polypropylene copolymer (b).

An array of linear foam strips designed to be vertically stacked with their linear axes parallel and vertically aligned under a region of a mattress that requires a raised contour on its top face to alleviate a medical condition or to repair a sag in the mattress. The foam strip arrays come in 24 or 32 inch lengths to correspond to the width of standard mattress. Each linear foam strip has a different width but none of the strips are within 25% of the width of any other foam strip. The widths of the four different foam strips in the array has been carefully sized to allow the best possible combinations to develop the proper height and side slope of the contour developed in the mattress's top face.
