Firmness Info The Ergoflex mattress is a result of over a decade of research and development. Our one 'perfect' mattress, rated medium/firm is optimised with the highest-quality materials available, and has over 5,000 5-Star reviews from customers in Australia, the UK, Europe, Asia and the Americas. While it's still classed as medium-firm, the Essential is slightly softer than our original range. This is because of our uniquely-designed cover and slightly thinner layers, which helps you sink into mattress, while still providing that key support that ensures you wake up pain or niggle-free. On a firmness scale, we'd rate the Essential on 6/10.

Mattress Construction

Materials Overview As the most premium mattress in a box in the UK, the Ergoflex 5G comprises of:
  • 9cm of genuine High Density Visco Elastic Memory Foam
  • A unique Cool-Sleep airflow system perfectly designed for the UK climate
  • A superior base layer for support and longevity of performance
  • All combined with our luxurious TENCEL® outer cover for unrivalled comfort.
The OTTY Essential mattress is at an industry-leading price point (up to £275 less than our other boxed mattress competitors) and is a five layer construction:
  • Cool Blue Gel Infused Memory Foam
  • HD Reflex Foam
  • 14cm Encapsulated Pocket Springs
  • HD Base Foam
  • Airflow / Side Support.
Comfort Info Ergoflex comparable only to TEMPUR® is technically more advanced and superior in performance to every alternative both in this price range and beyond. As a result it is renowned for delivering deep restorative sleep. It is recommended by Practioners for those that suffer from back pain, fibromyalgia, circulation problems and joint complaints or to those simply in need of a good night's sleep. The space created by our 14cm pocket springs helps to provide the maximum airflow, which complements our Cool Blue gel-infused layer, regulates the temperature of the mattress and gives you a better night's sleep. Ultimately, this airflow system eliminates the likelihood of overheating which has been traditionally linked with memory foam products.
Support Info Our mattress is the only true high density memory foam mattress available. Designed to mould itself to the contours of your body it provides instant comfort, more support and better sleep. This confidence is matched by our customers making repeat purchases for additional mattresses time and time again. The OTTY Essential has up to 1,000 14cm tall pocket springs for great support. Our springs are the tallest in the boxed mattress industry and tower over the 2cm springs found in most of our competitors' mattresses. Ultimately, a longer spring makes all the difference to how well the mattress aids your posture, and is often the key component in ensuring you wake up pain and niggle-free.
Comfort Specs The Ergoflex 5G consists of an unrivalled 9cms of open-cell 85kg/m³ high-density memory foam. Our unique Cool-Sleep airflow system encourages air to freely circulate thorough the mattress keeping you cool while you sleep. Our base layer provides perfectly weighted support for the upper layers and longevity of mattress performance. The top layer combines gel-infused foam technology that regulates your body temperature, keeping you at the optimum temperature for sleep in the depths of winter or on a sultry summer night.
Support Specs Our class-leading zero disturbance technology has been a distinctive feature for over 10 years. Promoting deeper, more restful sleep it reduces the likelihood of being woken by a restless sleeping partner. Indeed our ten-year guarantee is underpinned with confidence of a decade of success. Unlike other brands we know our mattresses stand up to our warranty claims - as we have done it in real life for over a decade. As the Essential hybrid mattress contains 70% spring (the typical competition range from just 10%-36%) to 30% foam, we are confident that our mattress will give you the best support and comfort combined, especially for those side sleepers who create more pressure naturally or those with ailments or health issues. The springs also minimise motion transfer - so you won't be disturbed if your sleeping partner moves throughout the night.
Fabric Specs Our TENCEL® outer cover provides a luxurious, natural and breathable surface which can be removed and machine washed whenever you wish. This combined with our premium foam means that you can be sure of a comfortable sleep night after night. Hypo-allergenic Washable Cover
Our luxury thick knit cover creates a soft sleeping surface and can be unzipped and machine washed at 40°C
