A 29″ × 29″ seat cushion fits extra-deep sofas, sectionals and lounge chairs. At this size a thicker cushion keeps the seat from feeling flat, and Dry Fast foam keeps it usable after rain. We cut every cushion to order, so you get the exact size your frame needs, not the nearest stock size.

Questions
Is 29x29 a standard outdoor cushion size?
It is a common size for extra-deep seating, but frames vary by brand. Measure your frame and enter the exact size; we cut in ¼″ steps.
Can I get just a 29x29 cover?
Yes. Order cover only to fit foam you already have.
What if my cushion arrives the wrong size?
We usually cut within 6 mm of the size you order. Our maximum tolerance is ±25 mm on length and width (±38 mm for cushions of 0.55 m² or more) and ±13 mm on thickness; if a cushion is outside that, we remake it free under our fit guarantee.
Should a 29x29 cushion be thicker?
Usually 5″ to 6″. A large seat with a thin cushion tends to feel hard and bottoms out sooner.
