A structure includes a first body member including a first interfacing side edge and a first interconnecting component at the first interfacing side edge and a second body member identical to the first body member, the second body member including a second interfacing side edge and a second interconnecting component at the second interfacing side edge. The first interconnecting component engages with the second interconnecting component to secure the first body member and the second body member together.

A seat includes a frame defining an interior space bounded by an outer periphery. A fabric portion extends radially inward from the frame. A plurality of bands is engaged with the fabric portion and a plurality of support members is coupled to one or more bands of the plurality of bands. Each support member includes a connection member and a contact member secured to the connection member. The contact members cooperate to form a support surface spanning at least a portion of the interior space.

Chair, more especially an office chair, comprising a seat plate (34) which is arranged on an undercarriage (12) and a backrest (14) which in the manner of a so called synchronous mechanism permit a synchronous movement of seat plate (34) and backrest (14), characterized in that the seat plate (34) is mounted laterally tiltable and the backrest includes two backrest supports (22, 24) whose lower ends are mounted pivotally independently of each other on the undercarriage (12) and are coupled in movement to the seat plate (34) in such a manner that by rearward pivoting of the support (22, 24) one side of the seat plate (34) is pressed down on the same side and the opposite side thereof is raised.

Disclosed is a functional chair capable of adjusting a height of a seat according to a body type and posture of a user. The functional chair includes a first seat configured to support a left pelvis, a second seat which is provided at a right side of the first seat and is configured to support a left pelvis, a frame which is provided below the first seat and the second seat to support the first and second seats, a backrest which protrudes from one side of the first and second seats in an upward direction to support a user's back, a seat pressure measuring unit which is respectively provided on the first seat and the second seat to measure pressure of the first and second seats and send a first pressure value and a second pressure value, a controller which receives the first pressure value and the second pressure value from the seat pressure measuring unit to generate a height adjusting signal for adjusting a height of the first and second seats, a memory which stores in advance drive command information corresponding to a difference between the first pressure value and the second pressure value, a first height adjusting unit which is provided between the first seat and the frame to adjust the height of the first seat according to the height adjusting signal from the controller, and a second height adjusting unit which is provided between the second seat and the frame to adjust the height of the second seat according to the height adjusting signal from the controller.

The subject matter of the invention is a convertible bi-functional chair for sitting and kneeling, which allows to change positions and relieve the spine during long-lasting work involving sitting or long travels by plane, bus or train.

The bi-functional chair for sitting and kneeling comprises a movable rotating seat (1), back rest (3) and knee support (6). It is equipped with devices allowing to change the distance between the front edge of the seat and the back rest, the angle of inclination of the back rest with regard to the seat and the height of the back rest with regard to the seat, which enables converting the seat and back rest for classic sitting into a seat and back rest for kneeling and vice versa.

A sensory lounging chair system and method of use. The system generally includes a frame, a pump, air tubes connecting the pump to a pair of inflatable air tubes, pressure release valves, piping and hardware, a pressure sensor, and a fabric cover. In a preferred embodiment, the pump and pressure sensor are powered by a power supply connected to a terminal board, which in turn is connected to the pump and the pressure sensor. The fabric cover provides a comfortable barrier between the occupant and the air tubes, which initially are usually deflated or less than fully inflated. As the pressure in the air tubes increase, deep touch pressure is applied to the occupant's body in the places where the air tubes are in contact with the occupant. Deep touch pressure is thus applied to the occupant via contact with the tubes through the fabric cover.

A seat assembly for task-oriented seating comprises a seat support and a seat coupled to the seat support. The seat is movable under load, such as from the user's weight and movements, relative to the seat support. The seat has a cushion molded over a supporting armature with multiple bias elements. The seat and seat support are configured to deflect by predetermined amounts at defined locations over an extent of the seat assembly. In this way, the seat assembly provides for a range of comfortable and effective positions for users engaged in different active motions and having different preferences and sizes.

The invention relates to a recliner device for supporting a lying person, the recliner device having a foot and arranged thereon (i) a first movably mounted thigh support for supporting the first thigh of the person, (ii) a movably mounted second thigh support for supporting the second thigh of the person, the second thigh support being independent of the first thigh support and being combinable with the first thigh support to form a complete support, and (iii) a movably mounted back and head support that is independent of the first and second thigh supports.
