King Size Beds

King-size beds measure 5'0" wide (150cm) and 6'6" long (200cm) — both wider and longer than a double, making them well suited to larger bedrooms or taller sleepers. Shop king-size bed frames, divan beds and mattresses in a range of styles, all with free UK delivery included as standard.

Is a king-size bed right for your room?

A king-size bed gives couples noticeably more personal space than a double, and the extra length — 6'6" compared to 6'3" on a double, three quarter or single — makes it a better fit for anyone over roughly 6'3" who needs more legroom. It does need a larger room to avoid feeling cramped, so it's worth measuring your space, including wardrobe and door clearance, before choosing this size over a double.

A king-size divan base with storage drawers is a practical way to make the most of a larger room without needing additional furniture, while a king-size bed frame offers more choice on headboard style and overall look. Match either with a king-size mattress — we stock a full range of firmness levels and constructions to suit different sleep positions and preferences.
