Both mammoth and bensons know that the route to success and positive customer outcomes lies not in making claims about products, but in proving them. In both clinical and independent tests mammoth have proven its medical grade foam's ability to improve sleep, deliver greater postural support and offer superior pressure relief in comparison to standard memory and sprung mattresses.

19cm medical grade foam™  with no need to flip, just simply rotate. This unique material - the next generation of memory foam - keeps your spine perfectly aligned and reduces back, neck, shoulder and hip pain.

Posture cells™  which are 69% faster cooling 46% more pressure relief when independantly tested against 50kg memory foam, are incorporated into the freedom mattress collection.

Integrated & easy to zip off washable tencel mattress protector which is both anti allergy andhygienic. Tencel is a four way stretch fabric which helps to disperse heat and moisture and is also clinically proven to be suitable for those with sensitive skin, eczema and rhinitis.

Designed and manufactured in the UK.

Ratings and Reviews

Customer Reviews

4 out of 5 stars
Reviewer: Lee
"This mattress is really quite soft. Probably too soft to be classified with a firmness rating of 3. If you're heavier like me you will sink into the mattress."
Reviewer: Lee
"Be careful with this mattress. Not sure that it should be classified as medium. We have found this mattress to be actually very soft (just try sitting on the edge and you will see how much it squashes down). If you're heavier (like me), you'll sink into the mattress. I am finding that it is forcing me to sleep in a hammock-like position and is now starting to hurt my back a little. It's questionable if it really is medium firmness."
Reviewer: JANET
"Very comfortable would recommend this mattress."
Reviewer: David
"I visited the store thinking I wanted a Tempur but the second I tried the mammoth I knew there was no going back. No over heating, super comfy best night's sleep I have had in ages. Recommend a mammoth to anyone looking for a new mattress."
