    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.

London GB Much softer than advertised
It feels comfortable at first
I’ve had this for a week and after every night of sleeping on it I wake up with back pain. Never had this problem with a mattress before. It is advertised as a medium but it is very soft.
