We’re a Which? Best Buy

Which? – the UK’s leading consumer advice body - independently tested the Ergoflex 5G mattress and scored it highly in all categories, commending it as a Best Buy mattress. The vigorous testing process includes simulating years of mattress usage, along with laboratory analysis of various performance elements such as body support and breathability. The Ergoflex 5G was particularly praised for its durability, among other areas, underlining the legitimacy of our ten-year warranty.

The Ergoflex 5G was also voted by Which? as one of their Top 10 Mattresses for 2019.

"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." - Which? Best Buy Review of Ergoflex 5G - June 2018

Hidden Depths. Not Hidden Surprises.

The high density visco-elastic memory foam top layer of the Ergoflex™ 5G is a generous 9cm deep, which results in improved comfort, better support and a mattress that lasts longer. It’s also nearly three times the depth of the top layers in mattresses from our heavily marketed competitors. We haven’t trimmed anything away to save on costs, and once you’ve experienced Ergoflex™ sleep we’re sure you’ll agree it was the right choice.

Often Imitated. Never Bettered.

The launch of the Ergoflex™ memory foam mattress in 2006 revolutionised the industry, offering a high-end mattress that performed as exceptionally as the most expensive on the market, at an unprecedently affordable price.

With one perfect mattress – made with the highest quality materials and engineered to provide optimum support for all, rather than a confusing selection of combinations - Ergoflex™ transformed the customer experience for good. Our pioneering online-only direct-to-customer retail model transformed traditional mattress buying, by cutting out expensive retail showrooms and passing considerable savings on to Ergoflex™ customers. By shipping our mattress vacuum-packed and compressed in a compact box we made the transportation and in-home installation process easier than ever.

It’s no surprise that the innovative approach that Ergoflex™ took over a decade ago has been imitated by so many other mattress brands appearing on the scene today. However, you can be sure that Ergoflex™ was the original and remains the best. Unlike those of our new competitors, every single claim we make for our mattress is backed with the confidence and experience of over a decade of success.

Ergoflex™ mattresses come with a ten-year guarantee. We know our mattresses stand up to our promises – they’ve done it, in real life, since 2006. Our ten-year guarantee is testament to the quality of materials, the craftsmanship and the expertise that goes into every Ergoflex™ mattress.

Service rating : well - they should look after repeat customers... I have purchased 4 of their mattresses but yet, no discount vouchers (e.g. Amazon) so we'll try someone else next.
Product : The mattress is good for one size fits all I think is going to hurt them in the long run, my eldest daughter is finding it too hard so will probably go somewhere else.

Service rating : Great service, mattress arrived on my desired delivery day and delivery man kindly carried it up two flights of stairs to my bedroom for me. It's also a great relief to be able to test sleep the mattress for 30 days.
Product : Best purchase I've ever made. This mattress is extremely comfortable, I don't feel any pressure points at all and it adjusts to all little movements immediately. Have also noticed that I need less sleep now to feel really rested. Whilst it had a funny manufacturing smell in the beginning, this disappeared after a few weeks. Can only recommend +++++
