Meliusly Heavy Duty Couch Cushion Support for Sagging Cushions (21x72) – Reinforced Plywood Sofa Board

Restore Comfort in Minutes

When cushions sag, seating can feel uneven and soft. The Meliusly Heavy Duty Couch Cushion Support slides between the sofa frame and seat cushions to restore a firm, level surface. No tools, no flipping, and no towels required — yet the difference can be noticeable as you settle in. This is a practical solution built for real living rooms, designed to deliver a solid, supportive feel without replacing your furniture.

Solid, long-lasting construction

Crafted with 8 mm reinforced plywood panels wrapped in industrial-grade fabric, this board is engineered to stay flat and firm under daily use. The anti-skid finish helps grip the frame and minimize shifting, while rounded corners guard upholstery from snags and wear.

Flexible fit for many sofas

Choose from 8 sizes to match your space: widths from 21 to 28 inches and lengths from 48 to 79 inches. It works with couches, loveseats, sectional pieces, and removable cushions—never with attached or non-removable cushions. Measure inside your sofa frame (length and depth) before ordering to find the right fit.

Simple, discreet installation

Slide the board under the cushions and it stays in place, hidden from view. The hinged slat design lies flat and invisible while keeping the seating surface firm. A fraction of the cost of new furniture, and installation takes less than a minute.

Built with care by a small family business

From a team that understands daily living, Meliusly offers support and reassurance. If the cushion support doesn’t meet your needs, our friendly team will work with you to address concerns.
