Dr Mark Craig

The mattress recommended by The Back Doctor

“When it came to choosing my own mattress, my professional reading and personal research led me to Ergoflex. I have found my own back pain has improved significantly and my energy levels are much higher. Now, I recommend this mattress to patients as part of a multi-modal treatment for back and neck pain.”

Dr Mark Craig

People with serious back and joint problems love Ergoflex.

The Ergoflex 5G mattress is made for everyone, but it’s exceptionally well-suited for those suffering from chronic conditions including back pain, fibromyalgia and joint stiffness.

“Perfect 10. The most comfy mattress. Have had other more expensive memory foam mattresses (marketed well) and they do not compare. I have arthritis in my hips and I get a good night sleep on this mattress.”

| Angela H. Verified Buyer.

“I was in constant pain every night in my lower back caused by a slipped disc before buying my Ergoflex mattress. I now have a good night sleep free of pain, I can’t believe that your mattress could make that much difference.”

| Merlina H. Verified Buyer.

Sleep like you used to

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.

“I suffer with back problems after having an accident and have peripheral nerve damage and have damage to the lower vertebrae in my back . From the first night I have had vast improvement in sleep as the mattress prevents me from moving around so much therefore I am not waking up in so much pain. I strongly recommend this product.”

| Mr Daker. Verified Buyer. Review Centre.

“I was already sleeping on a cheaper memory foam mattress and was having issues with lower back pain and could not get comfortable at all. Ordered the double… and have to say I cannot believe the difference this mattress has made.”

| D. Skipworth. Verified Buyer. Review Centre.
