Are UK bed sizes the same as European ones?

No. A UK double, king and super king have specific dimensions that differ from European and US sizes with similar names — so check the centimetres rather than the size name.

Does a bed frame come with a mattress?

Usually not. Frames and mattresses are priced separately and bundles are priced separately again, so compare frames against frames.

Is an ottoman bed worth the extra?

If storage is short, it is the main reason to spend more in this category. Measure the route into the bedroom first — they are heavy and awkward.

Cheapest place to buy a bed frame in the UK

A "king" bought from the wrong place is not a UK king.

UK sizes and everyone else’s do not match

A UK double, king and super king have specific dimensions that differ from European and US sizes of similar names. A frame sold by an international seller may take a mattress you cannot easily buy here, which turns a cheap frame into an expensive problem.

The mattress is almost never included

Bed frame listings usually exclude the mattress, and frame-plus-mattress bundles are priced separately again. Compare frames against frames, and price the mattress as its own decision.

What actually drives the price

Storage. Ottoman and drawer frames cost considerably more and are the main reason to spend here.
Slat type. Sprung slats support a mattress better than solid ones and affect how long it lasts.
Material. Upholstered, wooden and metal frames sit in different price bands.
Assembly, included by some retailers and charged by others.

Before you buy

Check the mattress dimensions in centimetres.
Confirm whether a mattress is included — usually it is not.
Decide on storage before comparing, since it changes the price band.
Check assembly and delivery charges.
Measure the route into the bedroom, particularly for ottoman frames.
