The UK bed size column puts the size each listing gives beside the six UK bed sizes of the National Bed Federation, the trade body for UK bed makers. A size name alone is matched by name, except on bed frames and bases, which need the mattress size their listings state; figures are matched in centimetres, exactly. How we build these lists
