Which layout?
- Single over double: three sleepers on two decks, two on the wider lower bed. It suits siblings or an adult on the bottom bunk.
- Bunk plus trundle: the third bed pulls out for sleepovers, for example the Flair Tag and Flair Zoom Detachable with Trundle (£299.99).
- L-shaped triple: spreads the beds around a corner. See L-shaped bunk beds.
Mattresses, height and safety
- Buy the mattress sizes on the product page: usually a 90 x 190cm single on top and a 135 x 190cm double (or 120 x 190cm small double) below.
- Keep to the stated maximum depth: for example, 15cm or less on the Zoom double bunk and Tag trundle. A deeper mattress reduces guard-rail height. See the bunk bed mattress thickness guide.
- The Flair Tag recommends the top bunk for children aged 6 and over. See bunk beds by age.
- Overall heights vary: 160cm for the Wholesale Beds No Bolt Metal and the Dorel Single Over Double. Check the product page height against your ceiling with ceiling clearance.
