Meliusly Heavy Duty Couch Cushion Support — 24x79 Reinforced Plywood Sofa Board

Restore a firm seating surface in minutes

Meet the Meliusly Heavy Duty Couch Cushion Support. This discreet board slides between your sofa frame and seat cushions to restore a level, comfortable seating surface—no tools, no flipping cushions, and no towel tricks required. If your couch sinks when you sit, you may notice a more balanced feel and a return toward how it performed when it was new.

Why choose Meliusly for sagging cushions

• Durable reinforced plywood: 8mm panels wrapped in industrial fabric resist daily wear and help maintain a flat, even surface.
• Anti-skid grip and rounded corners: The finish helps the board stay in place while protecting upholstery from snags.
• Long-lasting stability: Engineered to stay flat and firm under regular use, avoiding bowing or compression common with foam or cardboard inserts.

Size options and fit

The board is available in multiple widths from 21 to 28 inches and lengths from 48 to 79 inches, spanning standard couches to oversized sofas. Measure the inside of your sofa frame from arm to arm (length) and front rail to back rail (depth) before ordering. Not compatible with attached or non-removable seat cushions.

How it works and installation

Slide the board between cushions and the sofa frame. The hinged design lays flat and remains invisible under your cushions, providing a firmer seating surface without removal, maintenance, or frequent adjustments.

• No tools required; installation can take under a minute when you know your size.
• Once in place, it stays put, offering a refreshed feel for everyday lounging.
