high density foam 5 inch
If your seat cushions go flat after one season, high density foam 5 inch thick is the upgrade that keeps them full, firm and comfortable for years. This thickness gives deep, even support for sofas, dining benches and window seats without feeling too tall.
Why Choose 5 Inch High Density Foam
High density upholstery foam has more material packed into every cubic foot, so it resists sagging and holds its shape under daily use. At five inches, it hits a sweet spot: plush enough for lounging, yet sturdy enough for a seat that sees heavy traffic.

What to Look For
Check the density rating for durability and the firmness rating for feel, since the two are separate. Firm foam padding suits upright seating, while a slightly softer option works for casual lounging. Measure your frame carefully, and consider wrapping a 5 inch foam cushion in batting before adding your fabric cover for smoother, rounder edges.
