The Ergoflex™ 5G Memory Foam Mattress.

With Ergoflex's all new 5th Generation visco-elastic memory foam we're introducing the most supportive, pressure-relieving and comfortable mattress that we've ever made. With 85kg/m3 High-Density memory foam, internal cool-sleep™ air-flow system™ and high density impact-resistant foundation layer, the Ergoflex 5G memory foam mattress offers an objectively superior performance to alternatives both in this price range and beyond. Combined with our new TENCEL® material outer cover, which has been meticulously tested & crafted to deliver outstanding natural breathability and comfort, the 5th iteration of our long-established Best Buy mattress ensures the Ergoflex 5G redefines what a class leading memory foam mattress really can and should provide.

We’re a Which? 2018 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 2018 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.

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.
