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.

  • Orthopaedic pressure-relief.
  • Negates motion-transfer. Zero partner disturbance.
  • Unique layered composition with proprietary materials, including the highest performing available density levels - No comparable-priced alternative comes close.
  • Excellent health benefits, HD visco-elastic foams are used in hospitals throughout Europe.
  • Ideal for sufferers of back pain, fibromyalgia, circulation problems or joint complaints.
  • Asthma and allergy friendly - Hypo-allergenic and anti-microbial for dust mite and allergen resistance.
  • High ILD (indentation load deflection) Rating - Comparable with highest-priced TEMPUR® alternative.
  • Certi-Pur® & OKEO-TEX® 100 certified. Manufactured to BS 5852 and BS 7177 UK Safety Standards.

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.

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 in the UK and Australia in 2010, 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.

Our Story

Sleep Fresh with Anti-Allergenic

Sleep Fresh

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.

AU Standard Queen-Size Service:

Service: The service was well above the average standard for an on-line seller.
Product: Bought the mattress a year ago and still enjoy it very much. It's on the firm side but that's fine with us. The quality is very good and I haven't noticed any changes in shape or deformation on it.
AU Standard Queen-Size Service:

Service: I was told that the only available mattress was "Medium/firm" which was supplied. I do not find it firm enough and couples tend to roll together and sink too low which creates comfort issues.
Product: See the comments above in customer experience.
- Service:

Service: everything now I can sleep at night
Product: -
AU Standard Queen-Size Service:

Service: They explained everything well in terms of the produce and the process of delivery. Very friendly and I would recommend them.
Product: Took about two weeks to get used to it. We both find it a little bit too firm. We have added a masters topper to soften the mattress. Would have perhaps preferred a soft to medium option. Do like the memory foam though. I don't mind it now but my husband still mentions he is a bit achey by morning. I think it is the firmness of it. I also would have preferred a softer foam.
AU Standard King-Size Service:

Service: Great product, our second Ergoflex purchase. This time for our daughter. Amazing!
Product: So comfortable we love our mattress.
AU Standard King-Size Service:

Service: It is not hard to "Just deliver" when it comes to business, what is hard is doing it consistently. My direct and indirect family have purchased dozens of products from Ergoflex and it's refreshing to know that there is a sustainable Australian business that is not gouging their customers.
Product: "It's the best thing since sliced bread" , My grandparents would say that often about something new and fancy that actually worked. I would have to say that the mattress is a comfort to sleep on and actually does not end up being a sweltering heat box, something that many others normally do. Simply put, I've had solid sleeps for the past 7 years, can beat that.
AU Standard Queen-Size Service:

Service: prompt delivery, great product
Product: way better than my old foam mattress sleeping, cant say I like sleeping on any other mattress but mine now :-)
AU Standard Queen-Size Service:

Service: The Ergoflex mattress is a tremendous product for alleviating back pain where other mattresses have not worked.
Product: Exactly what we wanted, this has saved us from many restless uncomfortable nights.
AU Standard Queen-Size Service:

Service: Great mattress! Did wonders for my back, the wife and I split, she took the bed. I miss it dearly.
Product: The mattress was incredible. Absolutely a 5 star product.
- Service:

Service: Really great customer service, prompt when replying to enquiries and prompt delivery also. Great mattress - very comfortable and supportive without being too soft or too hard.
Product: -
AU Standard King-Size Service:

Service: Service was great, easy to purchase, delivered undamaged and on time
Product: The mattress came as described, I had done my research and knew it would be hard...I don't mind a hard mattress but this is rock hard. As it heats up with your body heat, you sink into it. I do sleep well on it, but it isn't a magical mattress to heal your injuries. My wife loves it, and has said back pain she was getting worth our last Mattress is all but gone. I'm a bit the other way, still wake with a sore back and shoulder...but I'm mindful these things are an individual experience, what works for someone else isn't going to necessarily work with me. Don't get me wrong, this is a high quality product, at a decent price, but personally next mattress will be another brand, unless ergoflex explore a softer option.
AU Standard King-Size Service:

Service: Very responsive and helpful throughout the process, particularly when determining delivery options to a remote area
Product: Excellent, very comfortable and supportive mattresses that cope with the disparity between the weight of my Husband and I
- Service:

Service: good
Product: -
AU Standard Queen-Size Service:

Service: 2nd purchase. Easy, on time delivery and great product. The first mattress is now more than 5 years old and still like new.
Product: Great quality, long lasting comfort.
- Service:

Service: Fast service. Mattress is much thicker than the one we bought a couple of years ago. Very comfortable. Good value too
Product: -
AU Standard Queen-Size Service:

Service: I recall the mattress arrived in a short time after ordering. They also responded positively to an enquiring email about returns. The service was/is excellent
Product: Despite some comments regarding heat problems in Summer I found that they failed to materialize. The memory foam has a peculiar feel and obviously lacks the bounce of springs. This by no means detracts from its comfort. I have no complaints and would recommend to anyone to give it a shot.
AU Standard Double Service:

Service: As always, their advice was extremely helpful and their service was very professional and efficient. I have been using their products for about 8 years and every product has lived up to and surpassed my expectation. Accordingly, I would have no hesitation in recommending their products and service to anyone.
Product: Great products and excellent service. I would highly recommend them.
- Service:

Service: Friendly service, prompt response, short delivery time and good packaging...great product.
Product: -
AU Standard Queen-Size Service:

Service: On time delivery, good responsive customer service
Product: Excellent memory foam mattress. Getting good sleep these days
AU Standard King Single Service:

Service: Mattress arrived quickly and exceeded my expectations. My 6 foot plus son who weighs in over 100kg says it is the most comfortable mattress ever and he now has the best sleep. We will definitely be replacing all our mattresses with Ergoflex.
Product: Excellent - best sleep ever
