upholstery foam high density 1.8
If your cushions sag after a few months, the foam is usually to blame. Upholstery foam high density 1.8 is a go-to choice for seating that needs to hold its shape, whether you are rebuilding a sofa, padding a dining bench, or refreshing patio chair cushions.
What 1.8 Density Foam Means
The 1.8 figure refers to density, typically measured in pounds per cubic foot. Higher density generally means more foam material in every inch, which helps cushions resist flattening and keep their support over time. Density is not the same as firmness, so a 1.8 density foam can feel soft, medium, or firm depending on how it is made.
Where High Density Cushion Foam Works Best
- Seat cushions on sofas, chairs, and window seats that get daily use
- Benches and headboards that need clean, structured edges
- Replacement couch cushion foam for tired furniture
Tips Before You Buy
Measure your cushion covers carefully, consider the thickness you need, and think about wrapping the foam in batting for a smoother, fuller look under fabric.
