Research and Resources for our Top Picks
In making this “Best Mattress UK 2020 and 2021” article, we:

- Spent over 50 hours writing and revising this article to provide you with the most informative and helpful content so you can find the best mattress for your sleeping needs.
*This Best Mattress UK list is our opinion and can be a great foundation, to sum up information about some of the top mattresses out there especially if you don’t know where to start or know what is out there. We always recommend you do your own research to come to a decision that makes you as a buyer happy.
Best Mattress 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.
