The biggest and best of all UK standard sizes, a super king size bed base is designed to support a mattress measuring 180 x 200 cm, providing plenty of room for you and your partner to stretch-out. But the biggest and best option in terms of sleeping area is a super king adjustable. These bed bases provide the equivalent couple's sleeping space of a standard super king size mattress, but with one big difference: each sleeper has their own long single mattress measuring 90 x 200 cm. Each mattress is supported by a motorised adjustable mechanism with its own individual infra-red hand set. TEMPUR® adjustable bases include massage units as standard for that extra touch of luxury.
