The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engageable with and disengageable from each other. The cushion includes a side wall insertable into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with each other. The first and second interlocking surfaces interlock with each other to removably attach the cushion to the frame.SELECTED DRAWING: Figure 5a |
