    Cool slumber

    Stay as cool as a cucumber - every night. Cool comfort gel works to keep you feeling refreshed. So you can say goodbye to overheating, even in summer!

    Cloud-like comfort

    Getting out of bed in the morning just got a little harder! The plush comfort memory foam layer cushions your body for snug comfort.

    This layer is infused with Mlily's cooling gel, for a fresh sleeping environment, every night.

    Total support

    Underneath, you'll find a superior flex support foam base. No matter how you sleep, this foam base adapts to your unique movements - for support where your body needs it most.

    Cocooning you during the night, this base moulds to the contours of your body for truly tailor-made support night after night.

    Just right

    We rate this mattress medium-firm. No more sacrificing on comfort - you can enjoy all the cosy comfort you deserve while getting the support your body needs.

    Keep allergies at bay

    The Gel 500 is wrapped in a soft, breathable knitted cover. This means you'll get a fresh night's sleep - every night.

    Keep those allergies at bay. This mattress is hypoallergenic too - say hello to a sneeze-free snoozing.

    Great for the environment

    This mattress is rolled up and easier to move around tricky corners - even into your attic room! It's great for the environment too. We can fit more rolled mattresses in, so we can deliver more in one go. Not only does this help us reduce our carbon emissions, but you also help protect our environment too.

    Your new mattress is ready to sleep on in a matter of hours. All you need to do is place it on your bed and unwrap it. Over the next few hours, it will expand to its full size!

    Created for you

    This is a single-sided mattress, so there's no need to turn. Simply rotate from top to bottom every three months.

    Sleep easy, the Gel 500 is built to last and comes complete with a 5 Year Guarantee.

Lovely comfy mattress, not too soft, just right, at least for me, I'm sleeping better but do struggle to get out of bed in the morning now.

If helps I'm 5'6" and 9st 6lbs (on a good day). Sleep on my side and feel fully supported, contours fine to my body shape.
