A foldable chair includes a seat panel having a first end portion and a second end portion, a pivotable support having a first end portion and a second end portion, the first end portion of the pivotable support pivotally connected to the first end portion of the seat panel, and a variable resistance support assembly pivotally coupled to the second end portion of the seat panel for selectively raising and lowering the seat panel. The variable resistance support assembly can include a housing, with a first spring and a second spring stored therein. The first spring can have a first pressure load and the second spring can have a second pressure load that is less than the first pressure load.

This invention provides a chair leg including a connecting column, a sliding base, and a swinging block; the swinging block includes a positioned swinging block, a ring spring, and a fixed block; the sliding base includes a sliding leg and a connecting block; and the connecting column is fixed to the sliding base via the swinging block. This chair leg is provided with a simple structure, easy production, lower manufacturing cost, and is capable of swinging in a certain angle of 360 degrees and giving users more comfortable seat experience.

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.

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.

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.
