Developed by a team of passionate sleep enthusiasts, Tweak is a new mattress phenomenon launched in March 2016. It’s a dual comfort mattress redesigned for couples, offering a bespoke, no compromise solution to a good night’s sleep. The Tweak mattress wasn’t created overnight. After 3 years of extensive tests and multiple prototypes, the Tweak was born as the ideal solution for couples who have different preferences when it comes to comfort levels. The mattress is made-up of 1,800 pocket springs, a cooling foam comfort layer, a hypoallergenic cotton cover and dual foam inserts in your chosen comfort level (soft, medium or firm).
