UK King Size Mattresses
The UK king size (150 x 200cm) is the upgrade most couples are really shopping for: noticeably more space each, plus extra length for taller sleepers.
Why choose a king size?
- It's 15cm wider than a double, a difference you feel every night.
- At 200cm, it adds 10cm of length over a double, a relief for anyone approaching 6ft.
- It gives couples more space than a double without the room demands of a super king.
- King is one of the most widely made UK sizes, from budget to luxury.
Allow at least 2.7m x 2.9m, with 3.2m x 3.2m comfortable; king sheets and a 230 x 220cm king duvet fit.
