medium density foam 1.8
Choosing medium density foam 1.8 is one of the simplest ways to give a cushion, bench or chair seat the right balance of comfort and support. The "1.8" refers to a density of about 1.8 pounds per cubic foot, a popular middle ground that feels supportive without the higher cost of premium high-density grades.
Why Choose 1.8 lb Density Foam?
This grade of polyurethane foam works well for everyday upholstery projects that see moderate use. It holds its shape better than lightweight craft foam and gives sewists and DIYers a reliable base for a polished finish.
Popular Uses
- Dining chair and kitchen seat cushions
- Window seats and bench pads
- Headboards and padded wall panels
- Throw pillow inserts and back cushions
- Occasional-use furniture and guest seating
What to Look For
Think about thickness first: thinner sheets suit chair pads and headboards, while thicker pieces suit seat cushions. Consider how firm you want the seat to feel, and plan to wrap your cushion foam in batting for smoother, fuller edges under your fabric.
