20x24 Outdoor Cushions

A 20″ wide × 24″ deep cushion fits many patio lounge chairs, gliders and the seats of high-back chairs. It is narrower than it is deep, so check you have not swapped the two numbers before ordering. We cut every cushion to order, so it fits your seat exactly.

Measure

Check your size

Measure the seat frame inside the arms: that is the width.
Measure from the front edge to the back rail: that is the depth. On a 20x24 seat, the depth is the longer side.
If the frame is 24″ wide and 20″ deep, order 24″ × 20″ instead.
