Restore firm, even support to a sagging sofa in seconds — no tools, no heavy lifting, no damage to fabric. Simply remove the cushions, lay the board across the frame, and replace the cushions. Done.

• Supports up to 400 lbs — thick multilayer composite solid wood construction; won't bend, warp, or crack under daily use
• Dimensions: 21.5 × 70 inches — foldable design fits most sofas, loveseats, sectionals, and chairs; fold down to fit smaller frames
• Anti-slip grip dots — keeps the board locked to the sofa frame without sliding or shifting
• Upholstery-safe — rounded edges prevent tears and scratches; soft 600D Oxford fabric top with moisture-proof non-woven backing
• No tools required — installs in seconds; stackable panels let you customize support level
• 3-year replacement coverage — if the board develops issues within 3 years, it will be replaced
