A 28″ × 28″ seat cushion fits generously sized deep-seat 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.

FAQQuestions
Is 28x28 a standard outdoor cushion size?
It is a common size for 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 28x28 cover?
Yes. Order cover only to fit foam you already have.
What if my cushion arrives the wrong size?
We cut to within ±0.5″ of the size you order. If it is outside that, we remake it free under our fit guarantee.
Should a 28x28 cushion be thicker?
Usually 5″ to 6″. A larger seat with a thin cushion tends to feel hard and bottoms out sooner.
