A back panel is supported by the seat panel. A pair of side panels includes one panel coupled to each tubular support. Each panel has an interior wall and an exterior wall. A periphery is provided between the walls. Each exterior wall has a continuous recess congruent with its periphery. The interior wall of each side panel has a discontinuous recess. An inverted U-shaped component extends above the seat panel and a horizontal component is below the seat panel.
