Eggcrate Convoluted Foam Mattress Overlays

For anyone confined to bed for long stretches — recovering after surgery, managing limited mobility, or spending extended hours resting — the constant pressure against the same points of skin is the real threat. Eggcrate convoluted overlays address that directly. The peaks and valleys of the convoluted foam distribute body weight across a shifting surface, improve air circulation against the skin, and cushion bony prominences like the heels, hips, and tailbone where pressure injuries most often begin.

The foam's soft, contoured profile lets it flex with the body rather than press back uniformly the way a flat mattress does. That ventilation and give is what makes eggcrate a long-standing, low-cost first step in pressure redistribution for both home caregivers and facilities.

Choosing between our overlays comes down mainly to thickness. Our 1-3/4 inch overlay (11740-CC) fits a standard twin surface and adds a gentle layer of comfort for shorter-term use. The 3 inch overlay (13050-CC) offers deeper cushioning for higher-risk or longer-duration bed rest, while the 4 inch overlay (SP42S-300) provides the most substantial support. For a smoother sleeping surface, the 2 inch convoluted pad (SP22S-000) balances comfort with a lower profile. All measure roughly 72" long by 33–34" wide to lay over a standard bed.

A few practical notes buyers ask about: these overlays ship without a cover, so pair them with a fitted or waterproof cover to keep the foam clean and protected. Place the convoluted (bumpy) side up, directly beneath a fitted sheet, and the foam does the rest.
