A seat for hip shaking is set on a surface of a chair while in use. The seat for hip shaking includes a seat member and a base member arranged under the seat member. A top surface of the seat member is disposed with a saddle-shaped seat surface for users to sit thereon while a spherical surface is projecting downward from a bottom surface of the seat member. The base member has at least one support part on a top surface thereof. The spherical surface of the seat member is moveably supported by the support part of the base member and is rotated at an arbitrary angle. When a user sits on the saddle-shaped seat surface, he/she shakes the hip or maintains the balance to get the benefits of exercise like horse riding.

The cushion for protecting spinal posture is for placing on a flat chair surface and includes a base member, a sacrum support member on the base member perpendicular to the flat chair surface, and a back support element at 90 or 135 degrees from the flat chair surface. The sacrum support member presses against the user's sacrum and forces the user's vertebral column to be perpendicular to the flat chair surface, thereby maintaining the straightness of the user's vertebral column.

A functional chair is disclosed. The functional chair includes a first plate that accommodates a hip and a thigh when a user is seated on the functional chair, a second plate that accommodates a waist and a back when the user is seated on the functional chair, and a connecting portion that connects the first plate and the second plate. The second plate may have an acupressure portion that adheres to the waist when the user is seated on the functional chair.

A seat, particularly for playing video games, includes a tubular frame, a seat surface and a backrest. The seat surface and the backrest are formed by a piece of cloth tensioned in the frame, and the frame includes two lower frame parts extending forward from the backrest and each having a curved progression which is convex in downward direction. Each lower frame part can have a front outer end and a rear outer end, and the two lower frame parts can be connected to each other close to their front outer ends and close to their rear outer ends by front and rear transverse frame parts, which can each have a curved progression which is convex in upward direction. A tubular frame and a cloth are configured for application in such a seat.

A pelvic tilt detecting chair is provided to a user to sit and configured to detect a pelvic angle of the pelvis of the user in sitting position. The pelvic tilt detecting chair comprises a base, a supporting component, a carrying component and a detector. The base has a horizontal surface. The supporting component comprises a first end connected to the base and a second end. The carrying component is moveably configured and comprises an installing surface coupled to the second end and a chair surface configured to contact the pelvis of the user. The chair surface and the horizontal surface form a tilt angle when the user sits on the carrying component. The detector stores a tilt angle threshold value and is configured to the carrying component to detect the tilt angle. The detector generates a warning signal when the tilt angle is not matched up with the tilt angle threshold value.

A lightweight seat for vehicles, in particular for rear seats of motor vehicles, has a carrier part, wherein the carrier part is produced from a dimensionally stable material and integrally includes at least one seat shell for a seat user.

A method for fabricating a custom anatomical cushion and a device to capture pressure controlled shape is provided. The device comprises, generally, a flexible membrane enclosing floating beads adapted to be completely immersed and freely moving inside a fluid. The device further comprises a mesh adapted to stop the floating beads from going outside of the flexible membrane as a result of a pressure increase or decrease inside the flexible membrane. The device is being fluidly connected to a pressure control system adapted to increase and/or decrease the internal pressure of the flexible membrane and comprises a vibration/leveling system adapted to adjust the fluid level inside the flexible membrane.

A cushion for supporting a user relative to a support surface is provided. The cushion has material with sufficient flexibility to deform under a weight of the user and sufficient resilience to return to its original state when the weight is removed. A supporting face contacts the support surface and is characterized by a plurality of points. The supporting face is contoured such that, when the cushion is in an unloaded configuration, a first subset of the plurality of points contact the support surface and a second subset of the plurality of points do not contact the support surface. When a user then sits on the cushion so that it is in a loaded configuration, at least some of the points in the second subset are displaced under the user's weight and contact the support surface. The cushion thus both bends and compresses to distribute the weight of the user.

The present disclosure relates to a breathable cushion. The cushion includes a thigh support portion, a hip support portion, and a waist and back support portion. The thigh support portion includes a plurality of thigh support structures each having an opening structure; the hip support portion includes a plurality of hip support structures each having an opening structure; and the waist and back support portion includes a plurality of waist and back support structures each having an opening structure. The area of the opening structures of the thigh support structures and/or the area of the opening structures of the waist and back support structures is greater than the area of the opening structures of the hip support structures. The cushion has the following advantages. The cushion has an ergonomic design and structure, and provides reasonable and reliable supports. In addition, the light-weight and highly comfortable cushion has good air permeability.

An orthopedic device; the orthopedic device includes a cushion having a left side and a right side having different heights to level and correct a lateral pelvic tilt in a seated user. In one embodiment, the left side and the right side may each include pads for supporting respective buttocks of the seated user seated with lateral pelvic tilt. In another embodiment, the cushion may be used for supporting just one buttock of the seated user seated with lateral pelvic tilt. A method for diagnosing lateral pelvic tilt and for using the orthopedic device to correct the lateral pelvic tilt is also disclosed herein. The orthopedic device is useful for relieving, or at least substantially relieving, back pain and pressure associated with lateral pelvic tilt.
