Should I buy an Ergoflex Mattress?

Ergoflex only make one mattress and they’ve spent a lot of time perfecting it. And this shows in the positive reviews it receives from customers. Ergoflex’s ethos was to make a mattress that competed with the more expensive Tempur mattress and feedback from sleepers suggests that it is a worthwhile alternative.

The Ergoflex mattress is particularly good for those with medical problems that cause body pain, as users report that they help to ease these and support the body extremely well. The mattress also has little motion transfer, making it a great choice for light sleepers and those sharing with a restless sleeper.

It’s worth noting that the Ergoflex sleeps considerably firmer than most mattresses in a box and this takes a little getting used to. But, once you are used to it, the mattress is extremely supportive and provides excellent pressure relief. A few customers don’t get on with the mattress – finding that the initially firmer feel exacerbates existing back problems, but in general this is an excellent choice for those in the market for a new mattress.

Which? awarded the Ergoflex a Best Buy Award, saying: You'll get great support …this mattress didn't sag, soften or become any less supportive, so you can count on it to stand the test of time.

The Mirror’s tester rated it highly for helping with his back problems: As for my back, of course no mattress will provide an instant cure, but combined with my physio regime, within a few days I definitely noticed an improvement – and within two weeks I genuinely felt my back was on the mend.

The Mirror

The Belfast Telegraph were also fans: I found that I drifted off more easily and felt less shoulder pain the morning after. The breathable material also stopped me from getting hot and sweaty.

I bought my first mattress 6 years ago, loved it, the best mattress, I have ever slept on, and is as new as the day I bought it. (July 2020)

Ergoflex Customer

We have slept on an Ergoflex mattress for the last 14 years (having taken the decision to purchase from reading reviews and sales advertising etc) We were so pleased, it is the most comfortable mattress we have ever had. Yesterday our new kingsize Ergoflex mattress was delivered (the old 4'6" one has moved to the spare room as it is still as good as new). The most comfortable night's sleep on the new one last night. So pleased! (June 2020)

I purchased the Ergoflex memory foam mattress as I was suffering with lower back pain during the night and I read that it was a good choice for that. After using the mattress for several months now I can say that there is a definite improvement in sleep and no lower back pain during the night. All in all a very comfortable mattress - would definitely recommended (May 2020)

Ergoflex Customer

We have bought 4 Ergoflex mattresses over the last ten years: two single, a king size and a super king size, and we love them all! To us these are the best memory foam mattresses available on the market. They are very well made with high quality materials, durable and super comfortable. And they cost a third of the price of Tempur mattresses, which are regarded as the best. In just a few words: great mattresses at a very reasonable price! Highly recommend! (February 2020)

Ergoflex Customer

This is the second Ergoflex mattress I have bought, and think they are wonderful. The first one I bought is now 4 years old and no sagging or deterioration in comfort level. From day one - I got a great night’s sleep. Cannot recommend highly enough - well done Ergoflex for great mattresses at an affordable price! (December 2019)

Ergoflex Customer

My son, who has a very painful upper back, has slept on his Ergoflex mattress for a couple of months now, and cannot praise it highly enough. He now has reduced back pain and has never slept better. I wish we had done this years ago. (September 2019)

Ergoflex Customer

Absolutely fantastic mattress, I can’t recommend it highly enough! So comfortable from day one & my back pain has improved massively. Thank you so much. I’m so pleased that I’ve recommended it to several friends who have since purchased an Ergoflex mattress. (August 2019)
