The Density Trap
Most DIYers make one fatal mistake: they confuse Density (Durability) with Firmness (Feel).
- Density (1.8lb, 2.5lb): How much the foam weighs. High density lasts longer. Always aim for 1.8lb+.
- Firmness (ILD): How hard it feels. 35 ILD is standard firm. 50 ILD is rock hard.
"Buying low-density foam (1.2lb) is why cheap sofas sag after 6 months. Spending $20 extra for 2.5lb High Resilience foam adds 10 years to your cushion life."
