Looking for an extra large bed?

When you’re looking for extra space in the bedroom, three solutions often come up: family bed (co-sleeping bed), Emperor bed (UK luxury format) and Alaskan King (the large, square “giant” from North America). Here you get a practical overview of dimensions, availability of bedding/accessories, delivery and space requirements – so you can make the right choice first time.

Quick definitions (typical dimensions)

  • Family bed: An extra-wide co-sleeping bed in modular dimensions, typically 240–360 cm in width and 200–220 cm in length (e.g. 240×200, 270×210, 300×200, 300×210, 360×210), available at www.fambed.co.uk. Often built on a foundation of 2–3 mattresses on a wooden frame.
  • Emperor bed: UK format. Typically 200×200 cm; some retailers offer larger variants around 210–215×210–215 cm.
  • Alaskan King: North American oversize. Standard is approximately 274×274 cm (108″×108″).

Alaskan King~274×274 cm (108″×108″)~137 cm per adult (2 pers.)Requires special fitted sheets/topper and often a special frame; selection is growing but still niche in the EU.Logistics, stairs, turns and door widths must be plannedRequires a large amount of space in both directions – the 274 cm/108 inches places significant demands on the room. Maximum space, a lot of unusable material and wasted length, so it is more about the luxurious look than practical usability.

Family bed: when co-sleeping is the goal

A family bed is in practice a wide, modular system. Typical setups:
  • 240 cm: 2 adults + baby/toddlers for shorter periods.
  • 270 cm: 2 adults + 1–2 children for everyday use.
  • 300 cm: 2 adults + 2 children with a comfort margin.
  • 360 cm: For extreme comfort and freedom of movement.
Advantages: Affordable, modular construction so you can get the size that suits you and your room, components can be replaced separately (mattresses, covers, toppers), designed specifically for co-sleeping.

Emperor bed: square luxury in UK format

The Emperor sits between the EU King (180×200) and pure oversize family beds. The square shape feels spacious, yet is still manageable in ordinary master bedrooms. Be aware that “Emperor” is not entirely standardised – some retailers offer 200×200 cm, others go up to around 210–215 cm. Advantages: Luxury feel and good sleeping space without extreme bedding/frames. Challenges: Accessories (fitted sheets/duvet covers) are not as widely available as for 180×200; dimensions should therefore always be checked against the manufacturer.

Alaskan King: the large square giant

The Alaskan King at approximately 274×274 cm (108″×108″) is significantly larger than both the Emperor and the EU King. It is designed for a maximum luxury look, high comfort for very tall people. Advantages: “No conflicts over space”, the option to lie across the bed, and a statement piece in the room – or dogs at the foot of the bed. Challenges: Requires an ENORMOUS room, special fitted sheets/toppers and planned delivery (stairs, door widths). High total weight and price level.

What should you choose?

  • Primarily co-sleeping (2 adults + 1–3 children): Choose a family bed based on the rule of thumb of 90 cm space per adult and 60 cm per child. Flexible construction, easy bedding, good value.
  • Couples who want luxury without niche accessories: Choose an Emperor (200×200) – just check bedding dimensions with the retailer.
  • Going for the ultimate luxury hotel look and have the budget: Choose an Alaskan King. Plan logistics and special bedding from the start.
