Mattress Construction

Materials Overview
Ergoflex, established in 2006, is the only mattress-in-a-box brand that has been around longer than the warranty. The Ergoflex 5G mattress is a true, high-density orthopaedic pressure-reducing mattress that comprises of 3 premium foam layers:
  • Tencel® Outer Cover
  • Protective Inner Cover
  • 9cm Visco-Elastic Memory Foam
  • 5cm Cool-Sleep Airflow Layer
  • 9cm High-Resilience Foam Base.
The Simbatex® Foam mattress by Simba is luxuriously deep (at 25cm) and has four layers of cooling, supportive sleep tech:
  • Anti-allergenic removable knitted cover
  • Open cell graphite infused Simbatex foam
  • Simba-Response foam
  • 7 zoned high density foam base.
Comfort Info
Sleeping on the Ergoflex 5G gives a feeling of pure weightlessness, allowing you to find that comfortable sleep position quicker. Zero partner disturbance technology reduces the likelihood of being woken by a restless sleeping partner, which allows you to experience deeper, more restorative sleep.
Simbatex® foam has 30x more airflow than dense, standard memory foam. It is also infused with natural graphite, which has an excellent ability to draw away excess heat.
Support Info
The Ergoflex 5G mattress is the only true high density memory foam mattress available, the ILD (indentation load deflection) is comparable only to TEMPUR®, and it is technically more advanced and superior in performance to every alternative both in this price range and beyond. Designed to mould itself to the contours of your body it provides instant comfort, more support and better sleep. This confidence is matched by customers making repeat purchases for additional mattresses time and time again. 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.
Simbatex® foam has an open cell structure which offers superior support and elasticity.
Comfort Specs
Visco-Elastic Memory Foam
This high density open-cell memory foam disperses heat more efficiently than previous generation memory foam. Cool-Sleep Airflow Layer
The upside-down egg carton-like design, built with temperature-regulation in mind, is a unique airflow system that encourages air to freely circulate thorough the mattress keeping you cool while you sleep.
Cooling, Cushioning Simbatex® Foam
A soft CertiPUR® foam, providing superior elasticity and 30x more airflow than memory foam. Infused with heat absorbing graphite for extra heat control. Simba-Response Foam
A firmer, open cell foam maintains airflow thanks to a less dense structure.
Support Specs
Visco-Elastic Memory Foam
A generous top layer of 9cm of true high-density visco-elastic memory foam provides supportive body-shaping performance. With billions of spherical shaped open cells, that intelligently respond under your weight to create the optimum level of body-cradling support to alleviate pressure points (such as the lower back, hips, shoulders). High-Resilience Foam Base
Nine centimetres deep, this high resilience impact-resistant foundation layer ensures perfectly weighted support for the upper layers. It provides class-leading performance and longevity.
Supportive Simba-Response Foam
A firmer foam that offers excellent support. Zoned, high density foam base
A notch-cut, high-density foam base provides zoned pressure relief to your body, with specific zones for the shoulders and hips and other potential problem areas.
Fabric Specs
Tencel® Outer Cover
This outer cover provides a luxurious, natural and breathable surface which can be removed and machine washed whenever you wish (machine wash at 30°C). Tencel® is naturally anti-bacterial, moisture-wicking, and sustainable. The breathability outperforms natural cotton and even the most hi-tech synthetics. It is also supremely strong and durable, yet luxuriously silky and soft to the touch. Vented 3D mesh panels at each end aid in preventing heat retention. Protective Inner Cover
This micro-fine inner cover protects all the foam layers.
A zipped, breathable cover, free from harmful substances (Oeko-tex 100 Standard) and suitable for allergy sufferers. This 500g hypoallergenic knitted top cover is removable and washable (washing instructions are included with the mattress) or combine with Simba's mattress protector for added protection.
