A pair of 21-in square seat pads, 4 in thick, sized to drop onto a patio chair or a kitchen chair and stay put. The cover is a durable polyester fabric chosen for wear resistance, which is what gives a cushion that lives outdoors a long lifespan rather than fraying at the corners after one summer. It is also both waterproof and oil-proof: rain beads rather than soaks in, and a spill wipes off instead of setting into a stain, so maintenance amounts to a cloth rather than a wash cycle. The fabric carries a sun protection function as well, which matters on a chair that sits in daylight for months at a time. The cushions themselves are soft enough to make a hard seat comfortable for a long sitting, and the workmanship holds the shape without deformation, so they do not settle into a permanent dip where someone always sits. A lightweight build means moving them off a chair before rain, or bringing them in for winter, takes no effort at all. Buying them as a pair rather than singly keeps a matched set of chairs consistent, with no risk of a second cushion arriving in a slightly different dye lot later. Both pads measure 21 in by 21 in by 4 in and arrive in orange, ready to use indoors or outdoors.
