Other Common Mattress Size Queries



• EU Sizes: Watch out! European mattress sizes are slightly different (e.g., EU single is usually 90cm x 200cm).
• US Sizes: Even more different, this includes the 'Queen'. Make sure you check before buying imported bed frames or mattresses.
• Custom Sizes: Have an oddly shaped space? Many retailers (including us!) can offer custom sizes on request.

What Size Should a Mattress Be for a Bunk Bed?



Bunk bed mattresses are typically a UK single (90cm x 190cm) mattress. Always double-check the depth too, many bunk beds have safety rails that need a mattress no deeper than 15cm to keep things secure but you can get deeper as long as there will be a 16cm gap between the top of the mattress and the top of the guard rails.
