Square Outdoor Cushions, Made to Your Size

Most patio chairs and sofa sections take a square seat cushion, but “square” can mean anything from an 18″ dining pad to a 30″ deep seat. We make square outdoor cushions to your exact size, cut within ±0.5″, in Sunbrella fabric that resists fading and mildew.

Measure

Measure before you order

Measure the frame or seat inside the arms, side to side and front to back.
Use the old cushion as a cross-check only: it flattens and shrinks with use.
Round to the nearest ¼″ and note rounded corners or notches for posts.
