BEN'SHOME Back Support Seat Cushion 23''x67'' Couch Cushion Support

✔ INSTANTLY FIX YOUR SAGGING SOFA - BEN'SHOME's heavy-duty solid 0.5" wood couch cushion support board slides under your cushions in seconds. Stops sinking, restores firm support, extends sofa life - no tools, no assembly, no damage to your sofa's fabric or cushions. Feel the difference from your very first sit. ✔ PERFECT FIT - MEASURE BEFORE ORDERING - Designed for deep-seat sofas 58"-67" wide with a 23" seat depth. Measure inner width (between armrests) and seat depth before ordering. Available in 28 sizes for armchairs, loveseats, standard sofas, large sofas, sectionals, and deep-seat sofas up to 30" deep. ✔ 0.5" SOLID WOOD, RATED 400 LBS - Built from genuine 0.5" solid wood - not the thin 0.43" plywood used by other brands that bends under pressure. Supports up to 400 LBS without warping, bowing, or cracking. No other couch cushion support board on Amazon matches this construction and weight rating. ✔ STAYS IN PLACE, ZERO DAMAGE - Double-sided anti-slip Oxford fabric grips cushions from above and sofa base from below - no sliding, no shifting. Safety-rounded corners prevent tearing or snagging your sofa's interior fabric. Stays completely hidden under your cushions - invisible in use, effective every sit. ✔ LIFETIME REPLACEMENT GUARANTEE - If your board warps, cracks, or breaks, we replace it for life - no questions asked. BEN'SHOME is a small family-owned U.S. business that created the original couch cushion support board - America's most reviewed, trusted by 8,600+ verified reviews from customers who finally fixed their sagging sofas.
