Foam Density and Selection Guide
Choosing the right foam ensures lasting comfort and client satisfaction. This guide covers the key factors.
Foam density basics:
1.5 lb density: Economy, light-use furniture, back cushions1.8 lb density: Standard residential, everyday chairs and sofas2.5 lb density: High-quality residential, heavy daily use2.8+ lb density: Commercial and institutional seatingDensity vs firmness:
Density (weight per cubic foot) determines durability. Firmness (ILD rating) determines how the foam feels. High-density foam can be soft or firm — they are independent properties.
When to use HR (High-Resilience) foam:
Family room sofas with daily heavy useCommercial seating (restaurants, hotels, waiting rooms)Any piece where the client expects 10+ years of lifeDacron wrap:
Wrapping foam in 1-inch Dacron batting softens the feel, rounds cushion edges, and helps fabric slide on during installation. Recommended for all visible cushions.
Thickness guidelines:
Seat cushions: 4-5 inches standard, 5-6 inches for deep seatsBack cushions: 3-4 inchesArm padding: 1-2 inchesRemember that foam compresses 10-20% under body weight over timeStill need help? Ask StitchDesk AI — click the chat bubble or press Cmd+J
