Who is a Single bed for?
A Single is made for one sleeper. It is common in children’s rooms, guest rooms and bunk beds. Some EU and IKEA frames take a 90 × 200 cm mattress instead, which is 10 cm longer.
How much room do you need for a Single bed?
Leave about 50–60 cm to walk beside the bed and at the foot if your room allows. That is a useful target, not a rule.
| Layout | Room width | Room length |
|---|---|---|
| Both sides free | 190–210 cm | 240–250 cm |
| One side against a wall | 140–150 cm | 240–250 cm |
Add the extra size of the frame and headboard. Divan bases are usually close to the mattress size; wooden bedsteads, sleigh beds and wide headboards are bigger. Try the bed room planner with your own numbers.
