Introduction

Choosing a good mattress is a bit like finding the right pair of shoes: it comes down to comfort, support… and to how you feel every morning. If you’re considering a memory foam mattress, you’re in the right place. This foam contours to the body and helps relieve pressure points, which can make a real difference for people who sleep on their side, or who wake up with aches and tension.

In this article, we’ll go over the essential criteria to choose the best memory foam mattress, without unnecessary jargon. The goal is that you can compare models on Amazon UK (and elsewhere) with confidence, instead of relying only on marketing promises.

Critères de choix

  • Foam density (not just thickness) : denser foam often holds up better over time. Check the density in kg/m³ when it’s provided, because it’s a useful indicator of durability.
  • Total thickness : in general, the thicker it is, the more comfort you get on the surface. But be careful: a high thickness with foam that’s too “soft” may lack support. The right balance also depends on your build and your sleep position.
  • Viscoelastic vs “memory” foam : some mattresses advertise “memory foam” but with different layers. The more layers there are—and the better they’re designed—the more precise the feel can be (comfort, support, and body-hugging).
  • Motion isolation : if you sleep with someone, good memory foam limits the movement transferred across the bed. You’ll wake up less when the other person changes position.
  • Firmness (or “feel”) suited to how you sleep :
    • On your side : a medium to fairly plush firmness helps fill in the shoulders and hips.
    • On your back : aim for solid support to keep your spine properly aligned.
    • On your stomach : too soft can push your hips downward; a medium to firmer feel is often more comfortable.
  • Thermal comfort (heat and ventilation) : memory foam can retain more heat than other materials. Look for models with a breathable cover, cooling treatments, or ventilation systems (channels, gel, etc.).
  • Cover and maintenance : a removable cover (ideally washable) is a real plus. And if you have allergies, check the cover’s features and how easy it is to clean.
  • Allergies and odors when unpacking : it’s common to notice a slight odor at first with some mattresses. Let it air out for a few days in a well-ventilated room. If the smell persists, it’s something to take into account.
