A folding chair comprises two front tubular legs, two rear tubular legs and a seat cushion board, with the front tubular legs intersecting the rear tubular legs. Two washers are arranged at an intersection of the front and rear tubular legs, such that each washer is located between a front tubular leg and a rear tubular leg. A pin passes through the front tubular leg, the washer and the rear tubular leg successively. The washer includes a curved base and a bowl-shaped support which is located in a central area of the curved base, and a through hole is formed at the center of the bowl-shaped support. The curved base is fixedly connected to the front tubular legs.

According to at least one example, a walking assist system includes a walker having a pair of laterally opposed upright tubular structures connected by at least one laterally-extending tubular portion. The walking assist system also includes a seating device having a first tubular structure formed in an inverted Upivotably connected by a hinge mechanism to a second tubular structure formed in an inverted U-shape. The seating device also defines a stowed configuration and a deployed configuration. The walking assist system further includes a retention clip defining a first opposing end configured to removably clamp to at least one of an upright tubular structure and the laterally-extending tubular portion of the walker. The retention clip also defines a second opposing end configured to removably clamp to at least one tubular structure of the seating device.

A store, move, and/or use apparatus for storing, moving, and using items implements an extendable support mechanism so that various work surfaces can be manually positioned at various elevations relative to the ground. The extendable support mechanism utilizes a plurality of support legs configured as a scissor lift. A storage container may be mounted on top of the extendable support mechanism. Additionally, wheel assemblies may be implemented to enable a user to move the apparatus.
