upholstery foam 8x24x80
Looking for upholstery foam 8x24x80? This generous slab measures 8 inches thick, 24 inches wide and 80 inches long. It gives you enough material to build a plush daybed mattress or a long window seat. You can also cut it down into several deep seat cushions from one piece.
Why Choose an 8-Inch Foam Slab
Thicker foam delivers noticeably more comfort and support than thin pads. An 8 inch upholstery foam slab works well for:
- Daybed and trundle mattresses
- Window seats and long bench cushions
- Replacement seat foam for sofas and lounge chairs
- Floor cushions and reading nooks
What to Look For
Density and Firmness
Density affects durability, and firmness affects how the cushion feels. Choose high density cushion foam for seats that get daily use. Softer options suit backrests and occasional lounging.
Cutting and Wrapping
A 24 x 80 foam slab trims easily with an electric carving knife. Wrap it in polyester batting before covering it with fabric. Batting softens the edges and helps your upholstery fabric fit smoothly.
