• STOP YOUR CHAIR FROM SINKING — This chair cushion support for sagging cushions slides between the seat frame and cushion to instantly restore firm, level seating. Works on recliners, armchairs, accent chairs, and dining chairs with removable cushions. If your favorite chair sags when you sit down, this chair support board eliminates the dip so you’re sitting on a firm, even surface again.
• REINFORCED PLYWOOD, NOT FOAM OR CARDBOARD — Built with heavy duty 8mm reinforced plywood panels wrapped in industrial fabric with an anti-skid finish. The chair seat support grips the frame to prevent shifting and keeps your cushion locked in place. Rounded corners protect upholstery from snags. Measures 17x22 inches — designed specifically for armchair and recliner seat dimensions.
• MORE THAN A SAG FIX — This under cushion chair support also firms up chairs that feel too soft, keeps cushions from sliding around, and makes it easier to stand up from low or sunken seats. Customers use it on recliners, oversized armchairs, reading chairs, and patio chairs with removable cushions. One board, multiple chairs in your home.
• INSTALLS IN 30 SECONDS, STAYS FOREVER — Lift your chair cushion, place the sagging chair support board on the seat frame, replace the cushion. That’s it. No tools, no trimming, no adjustments. Once installed, the board stays hidden under the cushion permanently — you won’t see it or feel it, just the firmness it restores. A fraction of the cost of reupholstering or replacing your favorite recliner.
