Square Mattress Gap Filler

Revive tired furniture with this versatile High-Density Foam Cushion Pad! Measuring 72x72 inches with 5 thickness options (2-6 inches), this ultra-soft yet supportive foam can be easily trimmed into custom shapes (rectangle, triangle, T-shape, trapezoid) to fit sofa cushions, dining chair seats, boat cushions, or bay window benches. Shipped compressed in a box, it fully recovers in 48-72 hours for long-lasting daily use—no need to replace old furniture, just refresh it!

This was perfect! We've got an old but high-quality, solid wood sleeper sofa. It can't take a very thick mattress, so the cushions have always felt a little low, and you can feel the metal bar of the bed frame. Ordered this pad, trimmed it to length and inserted it under the sofa cushions. The pad tucks in and is invisible, and the sofa is at least twice as comfortable as before. It's now appropriate for napping without opening it up. :). Kathleen. Brooklyn, NY. Mon Oct 12 2026

I should have bought this when I bought my Purple mattress 5 years ago! Using a regular box spring under a Purple mattress will cause the grid to lose its shape and creates valleys in the mattress. Placing the Bunkie Board on top of the box spring restored the grid to its natural shape, and NOW I sleep on the mattress just like I did when I got it home! I'll be buying these for EVERY SINGLE Purple mattress I own!!!. Yokasta. NM. Mon Oct 19 2026
