    Medical Grade Foam

    Medical Grade Foam

    Medical Grade Foam is carefully constructed to provide you with responsive support, superior comfort and exceptional pressure relief as you sleep.

    Individual Pocket Springs

    Individual Pocket Springs

    Each pocket spring is carefully and precisely engineered, then wrapped individually in its own soft cloth sleeve, which holds it at the optimum tension and allows each spring to move independently from the other springs. The pocket springs are held under the correct tension for responsive support. Since each spring operates independently, you can sleep in your own zone without affecting your partner, plus the mattress moulds more effectively to your individual body shape.

    Knitted Cover

    Knitted Cover

    The mattress is covered in a luxuriously soft knitted cover with the added benefit of being breathable.

    More Sleep Space

    More Sleep Space

    Foam encapsulated edges provide extra sleep space, keeping the mattress edges stable and preventing any sagging or bulging.

    Pressure Relief

    Pressure Relief

    Provides maximal pressure relief, by spreading more of your body's weight across the mattress - less toss and turning, more restful sleep.



    This mattress is hypoallergenic & resistant to dust mites, is ideal for asthma and allergy sufferers, or anyone looking for a healthier night's rest



    The ideal balance between a cushioned feel and a firmer level of support.



    Mattress depth 24cm (9.4") approximately.

    No Need To Turn

    No Need To Turn

    This mattress is purposely designed to be single sided for your convenience - there's no need to flip it over, but we do recommend that you rotate the mattress regularly.

    Roll Up Mattress

    Roll Up Mattress

    Your mattress is rolled up and boxed for efficient packaging and transportation, making it more environmentally friendly. Designed to expand once opened, roll-up mattresses usually take a maximum of 24 hours to reach optimum size. Roll up mattresses cannot be re-rolled once expanded. Please note: due to the larger size of Superking mattresses, these mattresses will be delivered flat and unrolled.

    Warranty: 10 Years

    Rise and shine with the Mammoth Rise Essential 1000 Pocket Mattress! This expertly designed mattress cares for your health and wellbeing, so you can enjoy the best night's sleep - every night.

    Perfect comfort

    The Rise Essential has been engineered for your total comfort. First off, you'll feel the soothing comfort of Medical Grade™ Foam. This clever material cradles your contours and is scientifically proven to enhance your comfort and sleeping quality.

    It's wrapped in a luxury quilted cover, so it looks as good as it feels!

    Soothes away aches and pain

    Say goodbye to aches, pains and soreness. The Rise Essential is a great choice if you need enhanced pressure relief. Mammoth's Medical Grade Foam™ is actually used by elite athletes, to improve recovery after training - so you can rest assured that it will care for you, too.

    Supports you where you need it

    Medical Grade™ Foam features Mammoth's PostureCell® technology. Both Medical Grade™ Foam and PostureCell® are approved by health professionals since they provide great postural support and care for aches and pains.

    But that's not all! The Rise Essential features three support zones and 1000 pocket springs for incredibly responsive support. Pocket springs provide superior support, to the areas you need it the most.

    Sleep right to the very edge

    Thanks to the foam encapsulation technology, you can enjoy maximum comfort right to the very edge of your mattress. Since the mattress edge is supportive and sturdy, you'll get maximum sleeping space and no rolling off the bed!

    Cool, fresh and hypoallergenic

    Medical Grade™ Foam is naturally cooling and won't heat up. Plus, the Rise Essential comes complete with a breathable airmesh border, to allow the free airflow. The result is restful sleep, with no overheating.

    The Rise Essential is hypoallergenic for your peace of mind. Of course, it's a great option whether you suffer from allergies or if you're simply looking for a healthier sleep.

    Great for you, great for our planet

    The Rise Essential is delivered rolled-up and boxed. This means it's easier for you to manoeuvre around tricky corners and up the stairs! It's easy to unroll, too. Simply place your new mattress on your bed and unwrap. Your mattress will take just a few hours to expand.

    Since rolled mattresses take up less space, we can deliver more in one journey. Fewer deliveries help reduce our carbon footprint.

    Please note: due to the larger size of Superking mattresses, these mattresses will arrive flat and unrolled.

    Simple to care for

    Single-sided for easy care, this mattress is simple to keep in great condition - so you can spend more of your time enjoying total comfort. You'll never need to turn it over! All you'll need to do is rotate it from end-to-end regularly.

    Quality you can trust

    Confident you'll love the Rise collection, Mammoth provide a 10 Year Warranty for your complete peace of mind. In order to benefit from this, please refer to the information provided within your mattress packaging, where you'll be asked to register your mattress on the Mammoth website.

This mattress is so comfortable. I can only describe it as being in a really luxurious hotel bed!

Really comfortable. The hybrid mattress is an excellent idea, and the foam doesn't have the same issues with requiring heat that memory foam does. It's a very warm mattress too - you'll notice how warm you are in this. The medium tension mattress really does feel like it supports well!
Just the smell - this is not a huge issue and isn't noticeable once you're in the room and ready to sleep. The room needs to be aired while the mattress is still settling in (it's only been 3 weeks) and the documentation clearly states that the smell will dissipate over time. It's not an unpleasant smell and the comfort far outweighs it!

Feels soft but gives great support. My nagging back ache that existed when I got up every morning with my old bed has completely gone.
There is a smell of foam which the paperwork warns might stay for a few months but either I have got used to it or it is fading quickly.
