About this product
This cushion support board is designed to fix sagging sofa cushions. It measures 70 inches by 21.5 inches and is 0.4 inches thick, made from black oxford fabric with a textured finish. It fits standard sofas and supports up to 400 lbs (181 kg). The board is firm and intended for indoor use. It comes as a single piece and requires no assembly.
Our take
This support board was a lifesaver for my sagging sofa. The 70-inch length fits my three-seater perfectly, and the firm support leveled out the cushions nicely. Installation was literally sliding it under the cushions—no tools needed. However, it's only 21.5 inches deep, so it doesn't cover deeper seats. Also, the board is quite thin (0.4 inches), so it adds minimal height. For the price, it's an effective quick fix, but don't expect it to restore brand-new firmness. Works best on moderately sagged cushions.
