A balance chair, comprising a seat, an in substance vertical height element supporting the seat, and a base supporting the height element and seat, distinctive in that the balance chair comprises a rotation and tilt element, arranged in a position in substance midway between the seat and a lower end of the base.

A seat for safety harness comprises a load-bearing framework formed by a one-way bending chain including multiple sequentially connected links, which form a support surface of the seat. A method of use of the seat for safety harness comprises, before the use, turning over the load-bearing framework so as to transit the load-bearing framework into its operational position. A method of manufacturing a seat for safety harness, the method comprising formation of a load-bearing framework by a one-way bending chain that includes multiple sequentially connected links forming a support surface of the seat. The use of the one-way bending chain for forming a load-bearing framework provides physiology-friendly abutment on ischial tuberosity so a risk of orthostatic collapse occurrence in the user is dramatically reduced. The seat does not impede walking when in the non-operational position, and its small weight and dimensions allow its use in sports and expeditions.

Detachable seats for shopping carts are disclosed. In one example, the detachable seat may include an inverted T shaped an inverted T shaped structure having a vertical hollow portion with an upper end and a horizontal portion. The detachable seat may further include a set of wheels connected to the two ends of the horizontal portion of the inverted T shaped structure. Further, the seat includes a pillar with a seat connected to its upper end, the lower end of the pillar may be inserted to the inverted T shaped structure through the upper end of the vertical hollow portion. Furthermore, lever may be pivotably connected to the pillar just below the seat, wherein the lever may be connected to a shopping cart.

The present invention relates to a single-legged portable working chair using a compression repulsive force of a spring body, wherein: when used, the telescopic single-legged portable working chair is worn on a user's body such that, when the user sits down, the spring body is compressed by the weight of the user's body to store power, and when the user stands up, the spring body pushes up the user's body using the compressed power, so that the power consumption required for the sitting and standing actions of the body can be reduced; when the user repeatedly lifts a weight, the load applied to the user's joints and muscles is alleviated by the magnitude of a repulsive force of the spring body.

A seating arrangement includes a rigid back frame, a flexible back shell coupled to the back frame and including a pair of vertical side portions and at least two strap portions extending laterally between the side portions and including a forwardly-facing surface configured to support a back of a seated user, the at least two strap portions including a lowermost strap portion, the lowermost strap portion configured to deflect a first distance when a rearwardly-directed force is exerted on the lowermost strap portion by a seated user, and a lumbar assembly supported from the back frame and configured to support the lumbar region of a back of a seated user, the lumbar assembly configured to deflect a second distance when the rearwardly-directed force is exerted on the lumbar assembly by a seated user, wherein the first distance and the second distance are substantially similar.

A sensory chair includes a seat support with a seat cushion having at least one compartment containing a bead-like media, a back support including a back cushion formed at least in party from a viscoelastic foam, and at least one weight attached to the chair, the weight being movable between a non-use position and a use position, wherein the weight in the use position is capable of overlying a portion of the body of a user seated in the chair. Thigh guides may be included to provide additional compression at the user's thighs.
