Dormeo S Plus vs Tweak - 2025 Review

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.

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.
