Will a cot bed fit in a small nursery?
Short answer: Cot beds are longer than cots, so measure the floor space with room to walk round and to convert it later. Leave space to walk round it and open drawers and doors.
- Check the mattress size listed for the frame. 140 x 70cm is common, but not universal.
- Keep every conversion panel, bolt and instruction sheet for the toddler-bed stage.
- Look at adjustable base heights, teething rails and any matching furniture.
What the guidance says
- If a full cot will not fit, the Lullaby Trust suggests a travel cot, set up with the same safer-sleep advice.
- Place the cot away from radiators, direct sunlight and blind cords.
