Supportive, Pressure-Relieving.
Comfort from Head-to-Toe.

The Ergoflex™ 5-layer sleep system consists of premium materials that work in harmony, combining to create the most supportive, comfortable and pressure-relieving mattress we’ve ever made.

Our TENCEL® outer cover provides a luxurious, natural and breathable surface, while the micro-fine inner cover encases and protects the entire mattress core.

A top layer of 9cm of true high-density visco-elastic memory foam provides supportive body-shaping performance and zero partner disturbance ensuring unbroken slumber for both users. The Ergoflex™ 5cm Cool-Sleep™ airflow system allows for air-flow and temperature regulation at the very core of the mattress and rests upon our 9cm high resilience impact resistant foundation layer ensuring perfectly weighted support for the upper layers and longevity of performance.

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™ true high 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.

  • Asthma and allergy friendly - Hypo-allergenic and anti-microbial for dust mite and allergen resistance.

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.

Often Imitated. Never Bettered.

The Original. And Still the Best.

Ergoflex™ revolutionised the mattress industry with our inaugural launch into the UK domestic consumer market in 2006 and Australia in 2010 with a class-leading High Density memory foam mattress at an affordable price. At the time, our online-only ‘direct to customer’ retail model completely disrupted the traditional mattress buying process, cutting out expensive middle-men and retail showrooms, and passing those considerable savings directly to our customers. Our one ‘perfect’ mattress, optimised with the highest-quality materials, was a world first – a business model that had never been seen in the consumer mattress industry prior. Moreover, our mattresses have always been compression-packed, vacuum sealed, rolled and delivered in a compact box for outstanding convenience.

So, it’s no surprise that our unique & innovative 10-year old approach has been imitated by so many other ‘start-up’ mattress brands arriving on the scene today, but you can be sure that Ergoflex™ was the original and remains the best.

Our ten-year guarantee is underpinned with confidence and the experience of a decade of success for the Ergoflex™ brand meaning that we know our mattresses stand up to our claims – we’ve done it, in real life, for over a decade. Ergoflex™, unlike many other brands that haven’t been around for long and use previous business ventures to give the impression of long standing credentials, Ergoflex™ has the genuine pedigree and experience that you can reliably trust over the long-term.
