Abstract: A back adjustment system for a chair having a frame that includes a top end and bottom end. The back adjustment system may further, include a chair back having a first end and a second end. The first end of the chair back may be mounted solely to the top end of the frame of the chair and also includes an adjusting means, which may be mounted at the bottom end of the frame. The adjusting means may allow for engagement between the bottom end of the frame and the second end of the chair back. The adjusting means may be adapted to telescopically engage between the bottom end of the frame and the second end of the chair back thereby solely moving the second end of the chair back from a retracted position to an extended position.

Abstract: Implementations of the present invention relate to a floor-mounted container that includes a rigid lower container portion defining an upper opening and a rim of the container, a flange extending from the rim and configured to support the container on edges surrounding a hole in the floor, when the container is mounted in the floor, and a lid with one or more trap-doors, the lid pivotally mounted to the rigid lower container portion and configured to pivot approximately 180 degrees from a covering position to an open position.

Abstract: A floor-mounting container and lid includes a rigid lower container portion having sidewalls defining a rim extending around as upper opening into the container, a flange extending substantially perpendicularly from around so as to rest the flange on an edge of the floor surrounding the container when mounted in a hole in the floor, and a lid having a 180 degree hinge and at least one trap-door in the lid.
