Designed for indoor use, the included white vinyl cushion provides guests with a comfortable place to sit during their visit. The cushion simply screws into the drain hole on the seat without the need for tools, which is practical for indoor usage, but can still be removed to retain the outdoor versatility of the metal chair. Adding a layer of foam between your guests and their seats will amplify their comfort, enticing them to stay longer and enjoy more. Aside from the comfort, this 1 1/2" thick cushion is made with CAL117 fire-retardant foam for added safety.
