Here we have another highly liked mattress on our Best Mattress UK list. The Leesa has gained attention from the likes of GoodHouse Keeping, Men’s Health and the Evening Standard.

The Leesa mattress is great at providing uniform pressure relief across the body regardless of the sleeping position.

The foams used are also  CertiPUR® certified and as CFC free. Ensuring no harmful chemicals are used within the making of the Leesa mattress.

Predominately the mattresses are sold over the Leesa website, but when you shop with them you receive a 100-night risk-free trial to test your new bed out that way you have ample time to really get used to it and decide if it’s for you or not. If you’re happy with the Leesa mattress and choose to keep it, youre backed in the long run with a 10-year warranty.

If you have been searching for a mattress online you have likely crossed paths with the popular Casper. Possibly the most well-known mattress in a box brand with over 1,213,446,201 Global sales. Possibly the first to pioneer the “bed in a box” concept.

The Casper is a 25cm tall mattress made up of four layers of foam. In addition to the diverse range of foams, the Casper also included castellated zoned support in the base layer to target pressure relief in all areas of the body.

This has all created a lovely memory foam mattress that isn’t too hard, too soft, hot or cold, ultimately it’s the mattress Goldilocks would pick. Comparing Casper to the other mattresses on this Best Mattress UK list, it is safe to say it is very competitively priced and is a top performer. Most would agree that the media attention that the Casper mattress has gotten recently is well deserved.

Approved by Good Housekeeping, loved by Real Homes, Which? Best Buy and finally, voted Product of the Year, there isn’t much more to say.

The Ergoflex mattress is engineered to be the best memory foam mattress for those who need a medium to medium/firm mattress. Memory foam has a slow response compression feeling with a gradual feeling. Memory foam does particularly well for those who suffer from back pain or injuries. It is a great mattress from those with orthopaedic issues as per the Back Doctor which has helped Dr Mark Craig recover from his back pain. There is no wonder it has been awarded a Which? Best Buy.

The Ergoflex mattress is CertiPur-US® & OKEO-TEX® 100 certified. Manufactured to BS 5852 and BS 7177 UK Safety Standards. This shows the dedication Ergoflex is putting into the manufacturing of their mattresses.

All the layers are then wrapped in a neutral white and grey cover which is made from Tencel fabric, which are fibres produced by environmentally responsible processes from sustainably sourced natural raw material. That way it is very unlikely to cause any allergic reactions.

Best Mattress UK by Type and Material

You may be wondering what is the best mattress type? well, this question is extremely subjective and depends on your sleeping position, body type, experiences and unique sleeping needs. Depending on your responses to these factors a certain mattress type may be better or more preferable for you.

Knowing the main points of differences may help get you closer to the best mattress for your situation.

Best Memory Foam Mattress

A memory foam mattress is a very popular choice as many sleepers enjoy the so-called “hugging” feeling it gives. Memory foam is arguably the best type of mattress to relieve pressure point pain. The biggest downside is it is known to sleep warm, however recent technologies are used to combat issues like these.

We have a whole article dedicated to explaining the different types of memory foams, their pros and cons and what to watch out for. Just head on over to our Top Memory Foam Mattress Picks.

Best Pocket Sprung and Hybrid Mattresses

Hybrid mattresses were created to solve the issues that only memory foam mattresses had as well as the issues that a pocket sprung mattress had. In short, infuse the two to create a mattress that has the best of both worlds. This does generally come at a cost.

Our Best Pocket Sprung and Hybrid Mattress Recommendations post goes into a deeper analysis. From spring gauge/thickness to coil count considerations and of course our top picks for the UK.

Best Mattress UK Conclusion

Making our list of the 10 best mattress brands in the UK for 2020 wasn’t a simple task. In the United Kingdom, there are dozens of mattress brands all with unique value propositions: But which is the best mattress?

Even though we landed on what we think are the best picks for 2020, we would like to mention that this list will always be evolving and our viewpoints are likely to change as new mattresses are released into the market. As mattress brands constantly change their data there may be some inconsistencies however, we are continuously updating our site to keep our information up to date.

We are not doctors or experts. At The Mattress Guide, we are a bunch of sleep enthusiasts that enjoy writing about all things sleep and have had years of experience in this field and we just want to provide you with as much information (in a digestible way) so we can at least make your life a bit easier when deciding which product to purchase.
