Choosing the right foam can turn a saggy couch into a seat you love. Most people think any foam will do, but density, firmness and material really matter. Below you’ll get straight‑forward tips you can use right now.
High‑resilience (HR) foam is the go‑to for most sofas. It bounces back quickly, holds shape and feels plush without getting mushy. Memory foam is great if you want that sink‑in feel, but it can get too soft for everyday use unless it’s blended with HR. Polyurethane (PU) foam is the cheapest option; low‑density PU will flatten fast, while higher‑density PU can work for budget sofas.
Density is measured in kilograms per cubic metre (kg/m³). A good sofa cushion usually sits between 30 kg/m³ and 45 kg/m³. Anything below 30 kg/m³ will feel floppy, and above 45 kg/m³ can feel too hard for long sitting.
Firmness is the feel you get when you press the cushion. A medium‑firm rating (often marked as 5‑6 on a 1‑10 scale) works for most living rooms because it supports the back while still feeling soft.
When you shop, ask the retailer for the foam’s density number and firmness rating. If they don’t know, press the cushion with your hand – it should give a little, then come back to shape within a second.
Why blend foams? Mixing HR foam with a thin layer of memory foam gives you the bounce of HR plus the gentle hug of memory. Many manufacturers now sell “dual‑layer” cushions that cost a bit more but last longer.
Another tip: look for foam with an open‑cell structure. Open cells let air flow, so the cushion stays cooler and resists mold. Closed‑cell foam feels firmer and can trap heat, which isn’t ideal for a sofa you sit on all day.
Finally, think about the sofa’s use. If you have kids or pets, choose a higher‑density HR foam that resists dents. For a guest room that sees occasional use, a lower‑density PU blend might be enough and saves money.
In short, aim for 30‑45 kg/m³ HR foam, medium firmness, and an open‑cell structure. Add a thin memory layer if you love that sink‑in feel. With these basics you’ll pick foam that stays comfy and holds up for years.
