This standard comfort glider cushion is available up to 8 inches thick. A boxed edge creates crisp corners and edges on the finished cushion. The addition of welting will accentuate this feature. Select indoor or outdoor fill and fabric for your glider cushion, as well as optional double welting and your choice of tie placements. We offer hundreds of name-brand fabrics from Sunbrella, Robert Allen, Outdura and more. Your finished product will be within ½" of your provided dimensions. Measurements do not include thickness of welting.
