A seat support with adjustment systems allowing a height and swivel adjustment functionality of the seat in a manner free of any wobble and shaking motion. The seat mechanism for height and swivel adjustments have screw adjustment applying a pre-load on a resilient component which gives a resilient force on a load bearing surface. The load bearing surface guides the seat part in motion during seat adjustment in a way to reduce friction and wear with use in time. The screw adjustment and the resilient component are configured such that play in guiding of the seat part in motion during seat adjustment is eliminated regardless of fabrication and component variations, and wear, with use in time. A screw adjustment locking device is configured to assure a stable adjustment with use in time.

A leg extension apparatus mounted to an existing chair leg to level the chair on an uneven ground is provided. The apparatus includes a bracket assembly having a leg bracket, a first shell bracket coupled to the leg bracket and having a first slot, and a second shell bracket pivotably mounted to the first shell bracket and having a first slot, the first and second shell brackets able to pivotably adjust to an open position to receive the leg of the chair and a closed position to permit the leg of the chair to be enclosed within the first slots of both the first and second shell brackets, and a leg slidably mounted to the leg bracket. The leg slidably adjusts to one of a plurality of locking positions to permit an end of the leg to contact the uneven ground, thereby supporting the chair in a leveled position.

A portable hunting seat includes a pole assembly having a first end and an opposing second end, the first end configured to engage a ground surface and the opposing second end spaced from the first end by a length of the pole assembly. The portable hunting seat includes a seat positioned along the length of the pole assembly, between the first end and the second end, and a gun rest extending from the second end of the pole assembly. The seat and the gun rest are movably coupled to the pole assembly such that the portable hunting seat is selectively reconfigurable between a deployed orientation and a transport orientation.

An occupational therapy assembly includes a sitting unit that has a first chair portion and a second chair portion. The first chair portion may have a first user sit thereon. The second chair portion may have a second user sit thereon. The second chair portion is positioned above and behind the first chair portion. Thus, the second chair portion facilitates the second user to view activities performed by the first user. The second chair additionally facilitates the second user to perform occupational therapy with the first user. A plurality of legs is provided and each of the legs is movably coupled to the sitting unit. Each of the legs may abut a support surface.

An adjustable seating solution that enables users to adjust several seating characteristics is disclosed. In a relatively low sitting position, the disclosed device provides some support if the user leans back, but predominately supports the user's weight and requires the user to engage core muscles to maintain good posture. The disclosed apparatus enables the user to adjust the seat upward to a leaning position. A platform extends forward under the user's feet to ensure that when the user leans against the seat, the apparatus remains stable. The apparatus enables the seat portion to be tilted, such that varying contours can be selected to engage the user's body in a desired way. At low heights, the user can tilt the seat portion forward to require the user to further engage core muscles while seated. At higher heights, the user can customize the contour of the seat that engages the user's body.

A hidden adjustable seat tube device for a bicycle has a lower tube assembly and an upper tube assembly. The lower tube assembly has a first rod and a driving element. The first rod has a mounting groove that is defined in an inner surface of the first rod. The driving element is mounted rotatably on the first rod. The upper tube assembly is mounted movably in the lower tube assembly. A manipulator is connected to the driving element. A transmission cable is mounted through the mounting groove and mounted in the manipulator and the driving element respectively. A retractable element is mounted inside the upper tube assembly, and abuts the driving element. The transmission cable is hid inside the lower tube assembly to organize the transmission cable easily and to mount the transmission cable in the bicycle neatly.
