The disclosure relates to a bunk, in particular for a vehicle cabin. The bunk comprises a base plate, an upper layer, a plurality of supporting members vertically compressible and spaced apart from one another substantially over the whole surface of the bunk, a plurality of pressure sensors which are part of the upper layer and in an adaptable area comprising at least one area of the bunk, a moving mechanism configured to move at least some of the supporting members in the adaptable area parallel to the base plate, and a control unit connected to the pressure sensors and the moving mechanism. The control unit is configured to cause the moving mechanism to move the supporting members in the adaptable area as a function of the current pressure data provided by the pressure sensors, to locally change the density of the supporting members to provide a locally variable bunk firmness.

A bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

The invention relates to a method for producing a cushion for an orthopedic device, the cushion having at least one fluid-filled volume, wherein the method includes compression molding of a three-dimensional first cushion component made of at least a first material, which is preferably elastic, in a mold that comprises an inner mold and an outer mold, and bonding the first cushion component to at least a second cushion component in such a way that the fluid-filled volume is created.

To provide a user with a new sensation through a tactile sensation, an auditory sensation, and a visual sensation, a human body support device has an overall shape that can easily be used as a chair or a couch. The human body support device includes a frame that is formed from, for example, metal or resin, and a plurality of modules that are arranged in a plurality of sites to support the user body on the frame. These modules include a sound emitting module that is provided with a speaker, and a vibrating and light-emitting module that is provided with an LED and a voice coil motor. These modules have an elastic part that is formed by an elastic material such as a sponge in a location that is in contact with the user body. The orientation and position of the modules are designed so as to be in proper contact with and support the user body, and accordingly, the user body can be comfortably supported.

A three dimensional mattress system is provided which may be configured to provide three dimensional body support to a user. In some embodiments, the system may include a rigid frame, and a frame cavity, in which the frame cavity is open at its highest elevation. A plurality of pillows may be contained within the frame cavity. At least a portion of the plurality of pillows may be coverless, and at least a portion of the pillows in the plurality of pillows are not physically attached to one another and are substantially independent of one another such that they can move freely within the frame cavity. The plurality of pillows may form a first body support area for supporting a first portion of the user, and a support unit may form a second body support area for supporting a second portion of the user.

A three dimensional mattress system with environment control is provided which may be configured to provide three dimensional body support to a user. In some embodiments, the system may include a rigid frame that may form a frame cavity. Optionally, the system may include one or more temperature regulators. A plurality of pillows may be positioned within the frame cavity, and a user may be supported by the plurality of pillows. Optionally, one or more air moving devices may be configured to move air external to the frame through the plurality of pillows, and one or more air filters may be configured to filter air moved by the air moving devices.

The invention relates to a supple member with adjustable stiffness for lying and/or sitting furniture. This member includes one or more adjustable helical springs and a rotary part. The rotary part includes a hub able to rotate about the central axis and one or more elastically flexible fingers. Each finger extends from a first end secured to the hub of the rotary part, over an arc of circle about the central axis, to a second end, and cooperates with a corresponding end of one or more of the adjustable helical springs.

The invention relates to a height-adjustable supple member for lying and/or sitting furniture, including one or more adjustable springs and a rotary part. Each adjustable spring is configured to change in height along a central axis under the effect of a radial stress relative to the central axis. The rotary part includes one or more rails each extending over an angular sector about the central axis, in a plane perpendicular to the central axis, from a first end to a second end more distant from the central axis than the first end. Each rail cooperates, in the radial direction relative to the central axis, with a corresponding adjustable spring among the one or more adjustable. The rotary part is able to rotate, about the central axis, so as to exert, through each rail, said radial stress on the corresponding adjustable spring.

The present disclosure provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the conical spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present disclosure further relates to a spring cushion having the spring module.

Variable stiffness apparatuses using an interconnected dual layer fluid-filled cell array. One example of the present apparatuses comprises: a substrate having a first side and a second side; and a plurality of structures coupled to the substrate, where each structure comprises: a flexible first portion having a first end, a second end, and a sidewall extending between the first end and the second end, the first portion defining a first chamber; and a second portion having a first end, a second end, and a sidewall extending between the first end and the second end, the second portion defining a second chamber in fluid communication with the first chamber; where each of the plurality of structures is coupled to the substrate such that the first portion is disposed on the first side of the substrate, and the second chamber is disposed on the first side or the second side of the substrate.
