Reflex Foam Explained

In short
Reflex foam is a UK retail name for firm, high-resilience polyurethane foam used in sofa beds, guest mattresses and some cheaper sleep surfaces. It bounces back faster than classic memory foam. It is not a medical grade. Density and thickness still decide how long it lasts. Treat the word as a foam style, not a quality score.

Frequently asked questions
Is reflex foam the same as memory foam?
No. Memory foam softens with heat and recovers slowly. Reflex foam is usually firmer and more bouncey. Both can be polyurethane, but they feel different and suit different uses.
Is reflex foam good for everyday sleep?
Thin reflex foam is common in sofa beds for folding space. For every-night sleep, check density, thickness and base support. A short guest mattress is not automatically a long-term main bed.
