Buying Guide
Sagging couches feel awful. The right inserts bring them back. Feel the difference in comfort and support.
- Foam Type and Density: High-density foam holds shape. Memory foam molds to your body. Choose based on firmness needs.
- Thickness and Support Level: Thicker cushions (4-6 inches) suit deep seats. Thin inserts (1-2 inches) fix minor sagging. Match to your couch’s design.
- Customization and Fit: Many inserts cut to size. Check dimensions before buying. Curved or foldable boards adapt to odd shapes.
- Durability and Longevity: Certipur-certified foams resist wear. Solid wood or plywood boards last decades. Avoid low-density options that flatten fast.
- Installation and Ease of Use: No tools? No problem. Sliding boards under cushions or unboxing foam pads takes minutes. Look for vacuum-packed foams that expand overnight.
- Additional Features: Anti-slip covers keep inserts in place. Ventilated layers prevent heat buildup. Removable covers simplify cleaning.
- Use Case and Placement: Seat cushions need firm support. Back pillows favor shredded or memory foam. Boards work for whole sofas. Match inserts to their role.
