Meliusly Heavy Duty Chair Cushion Support (17x22) — Reinforced Under-Seat Board for Sagging Cushions

Imagine your favorite chair returning to its former firmness. The Meliusly Heavy Duty Chair Cushion Support slides between the seat frame and cushion to create a stable, even surface that reduces the telltale dip you feel when you sit down. Designed for recliners, armchairs, accent chairs, and dining chairs with removable cushions, this board helps you maintain comfortable seating without the need for reupholstering.

What makes this under cushion support different is its construction. It uses an 8 mm reinforced plywood panel wrapped in durable fabric with an anti skid finish. The board grips the seat frame to prevent shifting, so cushions stay locked in place. Rounded corners protect upholstery from snags while keeping the look clean and unobtrusive under the cushion. At 17x22 inches, it matches common armchair and recliner dimensions.

Beyond a quick fix

• Restores a firmer, more level seating surface instead of sinking when you sit down
• Prevents cushions from sliding, preserving upholstery and setup
• Supports easier standing from low or sunken chairs

Versatility is part of the design. Customers use it on recliners, oversized armchairs, reading chairs, and patio chairs with removable cushions. One board can serve multiple chairs in your home, reducing clutter and cost over time.

Easy, lasting installation

Install in seconds and leave it in place. Lift the cushion, place the sagging chair support board on the seat frame, and replace the cushion. No tools, no trimming, and no adjustments. When in place, the board stays hidden beneath the cushion, maintaining the chair’s appearance and your comfort.

Quality and care from a small family business. Meliusly chair support boards have helped thousands of households address sagging seating. If it doesn’t solve your sagging chair, our support team is ready to help make it right.
