upholstery foam 1.8 lb
When you're rebuilding a sofa cushion or padding a dining chair, upholstery foam 1.8 lb density is one of the most dependable places to start. The "1.8 lb" refers to the foam's weight per cubic foot, a medium density that balances comfort, support, and value for everyday furniture projects.
Why Choose 1.8 Density Foam
Density describes how much material is packed into the foam, which relates to how well it holds its shape over time. 1.8 density foam is a popular middle ground: sturdier than lightweight craft foam, yet more budget-friendly than premium high density upholstery foam.
Common Uses
- Replacement cushion foam for sofas, loveseats, and armchairs
- Seat cushion foam for dining chairs, benches, and window seats
- Padding for headboards, ottomans, and RV dinettes
What to Look For
Density is only part of the picture. Check the firmness rating to match how soft or supportive you want the seat to feel, measure your existing cushion's thickness before ordering, and consider wrapping the foam in batting for a smoother, fuller look under your fabric.
