Mattress Topper Double

A Double mattress topper is sized to a 137 x 188cm Double mattress and rests on top of it, changing the surface feel while the mattress underneath stays in place. Double is the widest of the shorter NZ standard sizes, which puts it in guest rooms, sleepouts and smaller main bedrooms, and a topper at this width has to cover both sleeping positions across a shared surface. Betalife's topper builds are memory foam: a 5cm five-zone gel memory foam pad at 35kg per cubic metre, an 8cm gel memory foam pad at 40kg per cubic metre, and an 8cm dual-sided pad with gel memory foam on one face and firm foam on the other. Anti-bacterial bamboo fabric covers all three.
