Flexible foam is a general term for foam materials that can bend, compress, and return to their original shape without breaking or permanently deforming. It’s not one single material — instead, it refers to a category of foams made from different polymers (like polyurethane, polyethylene, or EVA) that share the property of flexibility.

| Type | Base Material | Common Uses | Key Traits |
|---|---|---|---|
| Flexible Polyurethane Foam (FPF) | Polyurethane | Furniture cushions, car seats, bedding | Very soft and bouncy |
| EVA Foam (Ethylene-Vinyl Acetate) | EVA copolymer | Sports gear, cosplay, shoes, mats | Smooth, resilient, heat-formable |
| Polyethylene Foam (PE Foam) | Polyethylene | Packaging, flotation, padding | More rigid but still flexible |
| Latex Foam | Natural or synthetic latex | Mattresses, pillows | Elastic and breathable |
| Memory Foam (Viscoelastic PU) | Polyurethane variant | Mattresses, medical supports | Slow recovery, pressure-sensitive |
Flexible Polyurethane Foam (FPF) is the standard foam used in furniture, car seats, and cushions. It’s soft, springy, and durable — perfect for comfort and support.
| Type | Density (approx.) | Feel / Use | Durability |
|---|---|---|---|
| Low-Density Foam (1.0–1.5 lb/ft³) | Soft, inexpensive | Temporary or decorative cushions | Short lifespan |
| Medium-Density Foam (1.8–2.5 lb/ft³) | Supportive yet comfortable | Everyday furniture | 5–8 years |
| High-Density Foam (2.8–3.5+ lb/ft³) | Firm, long-lasting | Premium sofas, mattresses | 8–15 years |
💡 “Density” measures how much foam material is packed in a cubic foot — not how hard or soft it feels.
Firmness is usually measured by ILD (Indentation Load Deflection): higher ILD = firmer foam.
