Pure Weightlessness.

Full support & complete comfort means deeper sleep.

The pressure-relieving Ergoflex™ 5G contours and shapes beneath you, providing a beautifully supportive environment that cradles your entire body. With a feeling of pure weightlessness you’ll effortlessly find a comfortable position, and drift off into a deep, restful sleep in no time. Since no part of your body goes unsupported you’re less likely to experience the aches and pains that come from spending a night in an uncomfortable bed, and you’ll experience a far better sleep quality as a result.

Pure Weightlessness on the Ergoflex Memory Foam Mattress

Benefits of the
Ergoflex Sleep System.

The Ergoflex™ 5G mattress is a true, High-Density orthopaedic pressure-reducing mattress, with temperature-sensitive responsive performance that contour to your exact body shape. Providing consistent support over the entire sleep-surface, the Ergoflex™ intelligently responds to support and alleviate pressure points (such as the lower back, hips, shoulders) and deliver instant and unrivalled comfort that lasts the entire night.

Designed with billions of spherical shaped open cells, the Ergoflex ™ 85kg/m3 density visco-elastic memory foam provides the optimum level of support & longevity, shifting responsively under your weight to create a body-cradling supportive sleep surface night after night, year after year.

Inclusive of its temperature-sensitive properties, the open cell foam and Cool-Sleep™ airflow system found at the very core of the mattress encourages air to freely circulate through the material, keeping you cooler than a standard memory foam mattress. This, combined with our new, all-natural TENCEL® fabric outer cover means that you can be sure of a comfortable night, every night.

Now with TENCEL^®.
Advanced Performance.
Direct from Nature.

Every Ergoflex™ 5G mattress comes beautifully encased in a tailored TENCEL® cover. TENCEL® is a botanical wonder-material; entirely natural and sustainable, with moisture-wicking and breathability that outperforms natural cotton and even the most hi-tech synthetics. It’s supremely strong and durable, yet luxuriously silky and soft to the touch.

The advanced moisture-wicking and quick-drying attributes of TENCEL® create a cool, comfortable surface that encourages undisturbed, peaceful sleep night after night, in every season of the year.

TENCEL is naturally anti-bacterial thanks to its cellular fibre construction, and achieves far superior hygienic performance compared to synthetics without the use of chemicals. It’s this combination of performance and purity makes TENCEL® the perfect fit for Ergoflex™.

Great Things
Come in Small Packages.

Every Ergoflex™ 5G memory foam mattress is vacuum-packed, rolled and delivered right to your door in a beautifully compact box. This makes it easier to manoeuvre into your bedroom, and upon opening begins the almost-magical transformation into your perfect mattress. We were the first to deliver our mattresses this way, starting back in 2006, and like all excellent ideas it’s now an industry standard.

*Transit packaging differs from image shown.

Sleep Fresh
Anti-Allergenic.

With a layered composition and anti-allergenic properties, the Ergoflex™ 5G mattress is inherently anti-microbial and resistant to dust mites and allergens. It’s also more resilient to the growth of bacteria, moulds, mildew and fungi - important triggers for allergenic and asthmatic responses, particularly in children. The Ergoflex 5G is certified to Certi-Pur® & OKEO-TEX® 100 standards and manufactured to BS 5852 & BS 7177 British Safety Standards.

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.

UK Standard King-Size	Service: Product:	Excellent
UK Standard King-Size	Service: Product:	Service rating : Service was fine Product : Had to replace after a couple of years - zero lower back support after 6 months, and now my wife has been struggling with the same. Been struggling with sleep with too long - had put down to stress but realised was being exacerbated by this mattress.
UK Standard Double	Service: Product:	I've purchased from ergoflex before and on both occasion service and product are excellent.
UK Standard King-Size	Service: Product:	Service rating : Excellent response to my emails. Product : Better than what I expected.
UK Standard Double	Service: Product:	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.
UK Standard King-Size	Service: Product:	Service rating : The ordering process was simple and the follow up information regarding confirmation, dispatch and delivery was excellent. Product : Both my husband and I have differing back issues and on the advise of our Osteopath was recommended to consider Ergoflex as a mattress for our new bed. We are both happy with our purchase of an Ergoflex mattress.

UK Standard Double	Service: Product:	Service rating : Easy to order, delivery exactly when indicated, even to a remote spot in West Wales.

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.
