Best 10 Memory Foam Mattresses UK (Updated 2021)

Memory Foam: How To Find Value ↓ Scroll to Top 10

Memory foam was developed over 50 years ago using a specialised process and blend of polyurethane. With its desirable slow response and contour, it has become popular in the likes of sofa cushions, car seats, and of course, mattresses. However, this 20th century revolution of memory foam brought many challenges, such as heat retention, lack of support, and high cost for quality.

Over recent years, however, there has been increasing development on the construction process in an effort to bring to market higher quality products with lower prices and better support. Also, gel infused foam and open cell technology are now must-have features for those worried about heat retention.

Off-gassing Considerations

Most foam, including memory foam, is a synthetic blend of polyurethane, which is a polymer generally derived in part from petrolium. These synthetic compounds may not be the best for your health and over recent years, there has been increased scrutiny put on foam that off-gass toxins. There are a few independent organisations that certify low emission foam, such as the CertiPUR standard. If you are sensitive to chemicals, make sure to check the certifications before buying!

What Makes a Great Foam Mattress?


The best foam mattresses aren't purely one type of foam. Their top layer is generally soft to the touch, but their middle and bottom layers are higher density and firmer to provide better support. The most comfortable foam mattresses are medium to medium firm so they don't swallow you, but provide a gentle contour to keep you comfortable. Nectar, with its multiple layers of open cell, high density cooling foam, and zoned base foams, does a great job at this!

Traditional memory foam tends to trap heat, but there have been some manufacturing techniques that help alleviate this, like gel infusion and open cell technology.


Choosing a memory foam mattress can be a difficult decision and sometimes the feel of the mattress doesn't agree with your body. Make sure to select a mattress with a generous trial and return policy.
