King Size Adjustable Beds

King Size Adjustable Beds

King size adjustable beds give more sleeping space in a 5ft size while adding electric comfort for reading, relaxing and resting. Choose a single 5ft mattress setup or a split 2ft6 + 2ft6 dual-operation option where each side can adjust independently.

King size adjustable beds are especially useful for couples who want more room, better positioning and practical storage options such as drawers or gas lift ottoman storage.

Why choose a king size adjustable bed?

A king size adjustable bed is a strong choice when you want a wider bed without moving up to a super king footprint. The 5ft size gives more room than a standard double while still fitting many main bedrooms.

For couples, the key choice is between one full 5ft adjustable surface and a split 2ft6 + 2ft6 layout. A split layout lets each side move independently, which is useful when partners prefer different reading, resting or sleeping positions.

King size adjustable bed options

Single 5ft mattress
Best when you want one uninterrupted king size sleeping surface with adjustable comfort.
Split dual operation
Two 2ft6 adjustable sides allow separate positioning and individual mattress choices where supported.
Storage choices
No storage, drawer storage or gas lift ottoman storage may be available depending on the product.

Standard and 25 stone mechanism guidance

The standard 5-part adjustable mechanism is intended for everyday comfort and is suitable for users up to 18st / 115kg. Where a stronger frame and mechanism is needed, a 25st / 160kg heavy-duty upgrade may be specified on request.

For split king adjustable beds, confirm whether the heavy-duty upgrade is required on one side or both sides. Also check mattress type, storage choice and delivery access before ordering.
