Cover
Purotex treated to reduce moisture and dust-mite allergens to create a drier, fresher and all-round healthier mattress. The probiotic treatment, works on the same principle as the probiotic yoghurt drinks, by putting friendly bacteria into the fabric of the mattress. As you sleep, your body pressure activates the friendly bacteria, which quickly multiply to outnumber and replace any harmful bacteria in the bed.
Hypo-allergenic, plush fabric cover. Our visco-elastic polyester blend cover provides a breathable sleeping surface. It's fire resistant and provides temperature control, plus it's hypo-allergenic making it ideal for those with dust or skin allergies. The zippable cover can be machine washed at 30 degrees and air dried, keeping your mattress fresher for longer.

Comfort
The 7 Zone mattress contains a deep premium comfort layer of body moulding memory foam for ultimate pressure-relieving comfort. The mattress provides unparalleled support for your entire body, with soft support for your shoulders and firm support for your hips and lower back, providing a healthier sleep. The high-density Miratex foam core means you'll be supported to the very edge of the mattress, meaning more sleep space for you.
The Tweak mattress (formerly known as the Nrem mattress) is designed to help all sufferers of chronic pain, including back pain. You can design your very own sleep experience by adjusting the foam tablets inside the mattress to give bespoke comfort and support to suit your specific pain needs. Pressure relieving, cooling comfort layer. This 4cm deep comfort layer contours and cushions the body for a greater level of comfort. The open cell structure wicks away moisture and keeps you cooler for longer.
Support
The 7 Zone mattress provides targeted spinal support for total body relaxation. The mattress offers soft support for your shoulders and firmer support for your hips and lower back. The result is that your spine stays level all night through, supported in its natural position.
5 customisable comfort zones with 4 different densities of deep foam. We use highly resilient Polyurethane foam in super soft, soft, medium and firm densities so you can get comfort and support in all the right places. This foam bounces back quicker than standard memory foam so you can turn over without feeling stuck. Our 5 comfort zones can be changed at any time so you can get your best night's sleep. 1,000 individual pocket springs for superior support and bounce. 1,000 full size pocket springs make up the mattress core. They're individually wrapped and move independently as you sleep, so you won't be disturbed by your partner's tossing and turning during the night. Our springs measure 10cm high and have a gauge of 1.5mm. As the springs are encapsulated in highly resilient base foam you get edge-to-edge support.
