The present invention relates to a functional chair with massage balls that is capable of allowing the massage balls to protrude outwardly therefrom through the manipulation of armrests to massage a user's muscles around the back and spine, thereby permitting the user's fatigue due to long sitting hours to be relieved. The functional chair includes: a seat; a seat support adapted to support the seat; a backrest having a plurality of massage holes formed penetratedly thereon; a backrest support having an inside partition extended from edges of an open surface; a pair of massage parts having the massage balls protruding from the massage holes or inserted into the massage holes; a pair of armrests adapted to rotate the massage parts; a seat connector adapted to fix the seat and the backrest thereto; and a stopper adapted to control rotation of the massage parts.

A torso supporting chair having a chair and front support. The chair has a seat support and at least one leg. The seat support having a top side and a bottom side, with the at least one leg attached to the bottom side. A front support is in functional combination the chair and may be integrally mounted with the at least one leg such that the front support is configured for seating of a user such that when the user is seated the chest of the user is adjacent and facing the front support. The torso support chair is configured to support the front torso of a user when seated.

A height adjustable, resting position unipod yoga body support prop is provided with an adjustable length multi-section leg attached at opposing ends to an upper platform for contact with a body part of a yoga user and an arcuate shaped base surface for a degree of forward and backward positioning adjustment of the yoga user when positioned on the upper platform. The unipod leg is adjustable in height to assist in assuming various yoga positions with the yoga prop. The upper platform, leg and base of the yoga prop can be disassembled for transportation and storage.

A method for using a back lifting chair designed for treating and preventing back problems by monitoring posture, weight distribution, and sitting duration of an occupant of a seating device, and reducing pressure on a user's spinal disc by adjusting the user's posture. The method allows for an up-lifting motion on the user's torso, reducing the weight and pressure asserted on the lumbar disc, and preventing any further damage to it. The method allows for an upward and downward movement, hence partially or completely lifting the user from the seat, effectively reducing the pressure on the user's spine and back. The upward motion can be initialized by the user, or alternatively, it can be automatically activated by the weight sensor installed on the seat device which detects the prolonged period of sitting.

A sitting device that encourages the active engagement of the user to remain upright. A seat (14) supported by a central column (12) passes through a pivot joint (16) supported by a base (10). The pivot joint (16) is located substantially at the median of the central column (12) between the seat (14) and the bottom of the base (10). The central column (12) pivots angularly providing the user mobility in his or her hips and lumbar, thoracic, and cervical spine. The central column (12) and seat (14) are brought back to vertical when the sitting device is not in use by means of a counterweight (18) affixed to the bottom of the central column (12). The length of the central column (12) may be adjustable to allow the user to select the desired height of the seat (14). The pivot joint (16) may be a spherical plain bearing, spherical ball bearing, gimbal bearing, spherical thrust bearing, or other device that allows the central column (12) to pivot angularly. The base (10) supporting the pivot joint (16) and central column (12) may contain as few as one leg and as many legs as needed to support the user. The movement of the pivot joint (16) may be inhibited by affixing a collar lock (40). The frictional resistance of the pivot joint (16) may be adjusted with a set screw (50).

An activating platform is disclosed. The platform includes a base that has a lower surface that is curved in a direction transverse to a longitudinal axis. The curved shape of the base provokes a user rock around in a small angle around a middle position, thereby promoting active sitting.

A back lifting chair designed for treating and preventing back problems by reducing pressure on a user's spinal disc. The chair provides an up-lifting motion on the user's torso, reducing the weight and pressure asserted on the lumbar disc, and preventing any further damage to it. The chair can be modified from an existing chair. In one configuration, a torso lifting harness which can lift the user's upper torso is connected to the backrest of the chair. The back rest of the chair provides an upward and downward movement, hence partially or completely lifting the user from the seat, effectively reducing the pressure on the user's spine and back. The upward motion can be initialized by the user, or alternatively, it can be automatically activated by the weight sensor installed on the seat area which detects the prolonged period of sitting.

The present invention relates to a smart induction charging type foldable multipurpose office/fitness chair comprising a seat frame, a hand exercise mechanism, a leg exercise mechanism, a control mechanism and a charging assembly. The seat frame comprises a buttocks support portion, a torso support portion and a head support portion. The buttocks support portion is provided with a first support rod and a second rod member. The head support portion is hinged to an adjustment plate. The hand exercise mechanism comprises a T-shaped handrail and a damping mechanism. The leg exercise mechanism comprises an inner sleeve, an outer sleeve, a tread plate, a roller and a T-shaped guide shaft. The charging assembly comprises a first coil, a first magnet, a second coil, a third coil and a second magnet. The present invention relates to a smart induction charging type foldable multipurpose office/fitness chair with a reasonable structure, which has the advantages of being simply constructed, convenient to use, multifunctional, safe and reliable, comfortable to use, etc., effectively solving the problem of employees not having time to exercise.

The present invention relates to a seat base for a saddle seat, the seat base (100) comprising a first face (102), the first face forming a planar surface to allow the seat base to be arranged on a surface to be seated, and a second face (104), the second face forming a concave surface, the concave surface restricting the lateral movement of the saddle seat by guiding the round lower part of the saddle seat towards the lowest point of the concave surface.

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.
