GORILLA GRIP Heavy Duty Couch Cushion Support Board – 96 x 21.5 in, Stay-In-Place Under Sofa

Solid, long-lasting support for sagging sofas

Upgrade your living space with a rugged couch cushion support board designed to add surface area and stability. The Gorilla Grip board covers a wide seating area and is sized at 96 inches long by 21.5 inches wide, making it a practical upgrade for oversized sofas that show signs of sagging cushions or worn-out cushions.

Durable, purpose-built construction

Built from premium .43 inch thick plywood, this board resists bending and wear, delivering a sturdy base under cushions. When evenly loaded, it can support up to 400 pounds, giving you a reliable foundation without changing the sofa’s look or feel.

• Premium materials provide strong, long-lasting reinforcement for seating surfaces
• Thick plywood maintains shape and resists compression during daily use

Stay-in-place design for everyday life

The underside features hundreds of slip-resistant grip dots that help anchor the board to the sofa frame, reducing shifting as you sit, shift, or lean. Rounded corners protect upholstery from snagging and tears during routine movement.

• Grip dots keep the board securely positioned on the frame
• Rounded corners minimize fabric snag and wear

Simple, flexible installation

Setup is quick and tool-free: remove cushions, unfold the panels, lay them across the sofa frame with the grip dots facing down, then replace cushions. The boards are designed to fold or stack to accommodate different sofa shapes, including loveseats.

• Typical installation takes just a few minutes
• Foldable and stackable design enables versatile, universal fit

Real-life use cases and expectations

Imagine a family room where the main sofa stays comfortable longer, with an even seating surface across the entire width. The extra surface area and solid base help maintain a tidy, consistent appearance as cushions settle over time. Results can vary depending on frame condition and cushion configuration, but the board offers a solid baseline for enhanced seating performance.

When measuring for a perfect fit, start by taking the seat width from inside arm to inside arm. This 96-inch board is designed for oversized sofas, and smaller boards can be used in combination if needed. This description keeps expectations realistic while outlining the practical benefits of a sturdy under-cushion support option.
