Before you buy a sofa bed: 10 checks for small spaces

In short

Measure the room with the sofa bed open, not closed: the open length is what decides whether it fits, and you still need room to walk round the end and one side. Check what has to move each night, try the mechanism yourself, ask how thick the mattress is and whether it can be replaced, and make sure it fits through every door, corner and stairwell on the way in. Read the return policy before you pay.

  4. Sources and method

In the shop, a sofa bed is judged as a sofa. At home, it fails as a bed: it does not open because the coffee table is in the way, or it opens and blocks the door to the bathroom. Most of these problems can be found with a tape measure before you buy.

The checks

Plan view of a sofa bed against a wall, closed and open, at the same scale with example sizes. Closed it is about 95 cm deep. Open it reaches about 220 cm from the wall, with room needed to walk round the end. A coffee table that would sit inside the open bed is marked in red: it has to move every night.
Same sofa bed, closed and open. Example sizes; use the maker's open dimensions. Das Hauskonzept

1. Open length, from the wall. Find the open dimensions in the product details, not just the closed depth. Measure from the wall where the sofa will stand and mark the open outline on the floor with masking tape.

2. Room to get in and out. Once the bed is open, you still need to walk round its end and get in on at least one side. If the open bed reaches a wall, a door or a wardrobe, someone will be climbing over the foot of the bed.

3. What has to move every night. A coffee table, a rug, a floor lamp. Each nightly move is a reason the bed will not get used. Note where those things go when the bed is open.

4. Doors and paths. With the bed open, can the room door, a balcony door and any wardrobe doors still open? Is there still a path to the bathroom in the dark?

5. The mechanism. Open and close it yourself in the shop, more than once. Ask whether you need to remove the seat cushions first and where they go. Pull-out, fold-out and click-clack mechanisms all work differently; the right one is the one you can manage alone, every evening.

6. The mattress. Ask how thick it is, what it is made of and whether it can be replaced. Lie on it, not just sit on the sofa. A thin mattress over a bar or a frame you can feel will mean guests sleep badly, or you do.

7. Bedding storage. Is there a drawer or a box for pillows and a duvet? If not, plan where they live during the day; on a small floor, bedding on a chair is clutter.

8. Seat comfort. It is still a sofa for most hours of the day. Check seat depth and height for how you sit, and whether the back is firm enough to lean on.

9. Delivery route. Measure every door, corner, hallway and stairwell between the street and the room. Sofa beds are heavy and often do not come apart. Ask the shop for the packed dimensions.

10. Returns. Read the return policy before you pay: whether returns are possible, who collects, and what it costs [1]. Policies vary between retailers and for large items [2].

Who it suits

A sofa bed suits a room that is a living room most of the time and a bedroom sometimes: guests a few nights a year, or a studio where the sofa doubles as the bed. If the bed is opened every night, compare it with a daybed or a proper bed with a room divider; our guide to arranging studio furniture shows layouts for both.

  • Open length measured from the wall and taped on the floor
  • Walking room round the end and one side
  • Coffee table, rug, lamps: where they go at night
  • Doors and the path to the bathroom still clear
  • Mechanism tested alone, cushions' place decided
  • Mattress thickness, material, replaceable
  • Bedding storage
  • Seat depth and height checked
  • Delivery route measured, packed dimensions asked
  • Return policy read
