How to Choose a Bed: UK Buying Guide (2026)

Q: What size bed do I need?

Choose by room and sleeper: single (90×190 cm) for kids and guests; double (135×190 cm) for couples in average rooms; king (150×200 cm) for comfort; super king (180×200 cm) for large rooms. Each person ideally gets 70–90 cm of width.

Q: Are ottoman beds reliable?

Yes, if the mechanism is good. Look for gas-lift pistons rated for the mattress weight, a base that stays open on its own, and safety certification. Cheap ottomans with weak lifts are frustrating and can be unsafe — spend £500+ for a reliable one.

Q: Do I need a headboard?

Not structurally, but headboards protect walls, make reading in bed comfortable, and finish the room. Many divans include one; most bed frames offer them as add-ons (£50–£150). Wall-mounted panels are a stylish alternative.

Q: What mattress goes with which bed base?

Memory foam needs a solid or closely-slated base (gaps under 7 cm). Pocket sprung suits sprung slats. Platform tops suit everything. The mattress and frame must be the same UK size — e.g. a 135×190 cm mattress on a double frame.

Q: How much should I budget for a bed and mattress?

For a double: £250–£600 for a good frame plus £250–£500 for a good mattress — £500–£1,100 all in. Spend proportionally more on the mattress; it affects your sleep far more than the frame.

Sizes in centimetres, storage options, frames and mattress pairing — the full walkthrough.

In short: pick your size from the UK standard chart below (double 135×190 cm, king 150×200 cm), choose divan for small rooms or a frame for style, check slat quality before anything else, and budget more for the mattress than the frame. Details for each decision follow.

What are the standard UK bed sizes?

UK bed and mattress sizes are standardised — memorise this table and you'll never buy the wrong bedding again:

UK bed sizes (mattress dimensions)

Size	Width × Length	Best for
Single	90 × 190 cm	Kids, teenagers, guest rooms
Small double	120 × 190 cm	Single sleepers wanting space; tight rooms
Double	135 × 190 cm	Couples in average UK bedrooms
King	150 × 200 cm	Couples wanting real elbow room
Super king	180 × 200 cm	Large rooms; co-sleeping families
Emperor	200 × 200 cm	Very large rooms (bedding harder to find)

Key rule: the mattress must match the frame size exactly. European (e.g. 140×200, 160×200 cm) and US sizes differ — a "queen" is not a UK king.

Divan or bed frame — which is better?

	Divan	Bed frame
Footprint	Compact — same size as mattress	Larger — headboard/footboard add 15–30 cm
Storage	Often built-in drawers	Usually none (unless ottoman)
Looks	Plain and functional	Wide style choice
Moving	Light, splits in two	Heavier, bulkier
Price (double)	£250–£500	£250–£800+

Our take: for box rooms, rentals and kids' rooms, a divan is the practical winner. For main bedrooms where the bed is a design feature, choose a frame you love looking at.

What storage options are worth it?

Ottoman (gas-lift): the whole under-bed area becomes storage — about 4 large suitcases in a double. Best storage per pound. Needs clearance to lift.
Drawer divan: 2–4 drawers, easy daily access. Needs ~60 cm pull-out space beside the bed.
End-lift ottoman: lifts from the foot end — good when bedside tables block the sides.
TV beds: combine ottoman storage with a rising TV. A luxury, but the mechanism warranties (5 years on good ones) are reassuring.

Storage capacity guide (double bed)

Ottoman: ~800 litres — duvets, suitcases, out-of-season clothes
4-drawer divan: ~300 litres — bedding, shoes, everyday items
2-drawer divan: ~150 litres — sheets, spare pillows

How do I judge bed quality?

Slats first: sprung beech slats are best; solid slats need gaps under 7 cm (critical for foam mattresses). Fewer than 12 slats on a double is a warning sign.
Joints: look for bolted or bracketed joints — wobble the display model side to side.
Centre rail: doubles and above need a centre support rail with legs to the floor, or the middle sags.
Weight rating: check the maximum user weight — quality doubles handle 200 kg+ total.
Upholstery: on upholstered beds, press the padding — it should spring back, not stay dented.

Which mattress pairs with which base?

Mattress type	Best base	Avoid
Memory foam	Solid platform or slats with <7 cm gaps	Widely spaced slats (foam sags through)
Pocket sprung	Sprung slats (adds comfort)	Nothing major — very forgiving
Hybrid	Solid or close slats	Widely spaced slats
Latex	Solid platform or close slats	Sprung slats (too much flex)
