The furniture leg attachment is an apparatus that is used to stabilize an uneven chair, table, or other piece of furniture. The apparatus is also configured to prevent sliding on rough or uneven surfaces, such as may be encountered during outdoor furniture use. The apparatus comprises a leg-receiving tube, a foot, a ball-and-socket joint, an incremental height-adjustment mechanism, and a plurality of ground-gripping protrusions. The leg-receiving tube connects to the foot by the ball-and-socket joint, which allows the foot to rotate and adjust relative to the surface that the table or chair is positioned upon. The incremental height-adjustment mechanism is part of the leg-receiving tube that allows the user to modify the height of the foot and the table or chair leg above the ground. The plurality of ground-gripping protrusions extends from the foot to grasp the surface that the present invention is upon.

A rotatable chair comprising a backrest unit, a seat plate unit, a supporting unit and a rotating unit; the rotating unit comprises an upper plate, a lower plate, a rotating disc, a connecting shaft, a first elastic ball and a handle; the backrest unit and the seat plate unit are fixed to the upper plate; the upper plate is provided with an upper locating hole; the supporting unit is fixed to the lower plate; the lower plate is provided with a plurality of lower locating holes; the rotating disc is disposed between the upper plate and the lower plate; the connecting shaft penetrates through the central position of the upper plate, the rotating disc and the lower plate at the same time; the first elastic ball comprises an elastic piece and a locating ball.

A foldable chair includes a seat member having a front side for supporting a user and a back side, a backrest member having a front surface for supporting the user and a back surface, and a plurality of legs. Each of the legs is pivotably connected to the back side of the seat member and each leg is adapted to pivot from a folded configuration where each leg is generally parallel to the back side of the seat member to an unfolded configuration where each leg is generally transverse to the back side of the seat member. The backrest member is configured to hingedly engage the seat member and to selectively enclose at least the back side of the seat member to form a portable case.

A seat surface part is switchable by a switching mechanism between a forward-unfolded posture in which the seat surface part is forwardly unfolded down so that a first support surface comes into a state at a low position where the seated person lowers his or her body to sit, and a second support surface comes into a state of forming a backwardly inclined surface that is inclined backwardly downward, and a folded-up posture in which the seat surface part is folded up backward from the forward-unfolded posture so that the second support surface is lifted up at a higher position than a position of the first support surface in the forward-unfolded posture, and an upper surface inclined forwardly downward is formed by the backwardly inclined surface so that the second support surface comes into a state at a high position where the seated person perches in a standing posture.

A staircase mountable chair assembly for usage while working on a staircase includes a pair of supports. The supports are attached together and have a shape to retain the supports in an upright position. A base is attached to and extending outwardly from the supports. The base lies in a horizontal plane when the supports are positioned in the upright position. The base is positioned on an upper step when the supports are on a next adjacent lower step. A post is attached to and extending upwardly from the base. The post has an upper end with a seat attached thereto.

Provided are systems and methods for a telescope observation chair assembly. The assembly includes a seat having a pad, a telescoping portion extending from the pad, and an adjustment assembly at least partially disposed interior to the telescoping portion. The assembly also includes a housing comprising one or more walls having one or more slots and one or more grooves cutout therefrom, the one or more walls receiving the telescoping portion of the seat. The assembly further includes a footrest.
