Mammoth Mattresses

The background of Mammoth's strive for excellence begins with medical research and support – not to forget to mention their NHS award winning work. This foundation has lead Mammoth to the point it is today, producing mattresses and beds that offer unparalleled support and unrivalled comfort. The unique material used in the mattresses were originally created for the healthcare industry, specifically for elite athletes, and while they are the go to brand for athletes, anyone can experience the comfort and rejuvenation a Mammoth mattress provides. Mammoth mattresses are designed with the very best materials and expertise in mind, and they have been tried and tested by professionals. These mattresses help you get to sleep quicker, sleep deeper and rejuvenate better than any other mattress can offer.

Mammoth Beds

While each Mammoth mattress is carefully constructed to offer the same level of sleep performance, their beds are also constructed with the same amount of detail and attention. Mammoth divan beds are available in a range of different fabrics to suit your personal tastes and styles. With a divan base it also provides the option of drawers, which makes it easier for you to maximise bedroom space and reduce clutter! Build your Mammoth bed online with My Next Mattress, or alternatively if you require further assistance regarding anything in our range, please don’t hesitate to contact us.

We offer a price match promise on all of our products, as well as a FREE sleep trial on all mattresses. For those wanting to enjoy the very best quality of sleep possible, Mammoth is the only choice.

Sleep Science

Mammoth don't have the 'Science of Sleep' tagline for nothing, they truly do explore every possible avenue when it comes to providing a good night's sleep. Their patented cell technology is designed to offer unrivalled support and their mattresses were designed from day one to achieve great sleep. No other mattress maker is applying the same level of research to their products.

Mammoth Sleep Trial

We understand that choosing your next mattress can be a bit of a minefield! For that reason, we offer a sleep trial on all items. So, you can choose your new Mammoth mattress and use it for 14 nights to ensure you're completely happy. Not quite sure? We can collect and refund you, or we can exchange it for another mattress! Trying a mattress in a showroom is not the same as trying one in your own home.

Mammoth - The Science of Sleep

Mammoth is the only current bedmaker in the Country to have been endorsed by the NHS. Not only that, but they continue to work with hundreds of sports professionals, including bodies like the Rugby Players Association, the Professional Cricketers Association, the British Athletes Commission, Tottenham Hotspur football club and many, many more. These sporting groups take the science of sleep very seriously and understand the essential need for the body to rest, recover and rejuvenate as efficiently as possible. Next time you're watching a professional sportsman or woman performing at their best, ask yourself which mattress they sleep on at night, the answer is likely to be a Mammoth mattress.
