Buying a sofa bed: what to consider about the bed function, size and everyday practicality

A sofa bed needs to serve several purposes: somewhere to sit during the day, a place to lounge in the evening and, when needed, a bed for guests. In small flats, studios, guest rooms or home offices, it can sometimes replace several pieces of furniture. However, eye-catching product claims don’t automatically mean you’re making the right choice.

Common sofa bed buying mistakes

1. “Compact” only refers to the folded position

A sofa bed for a small room needs to fit not only in sofa mode but also when pulled out or unfolded. So be sure to check:

  • Width and depth as a sofa
  • Sleeping area and extended depth
  • Distance from doors, radiators and other furniture
  • Space to move around in front of the sofa
  • Access to the room and any narrow points in the stairwell

A pull-out sofa with a large sleeping area can be impractical for everyday use if you have to rearrange the room completely every evening.

2. Soft upholstery is mistaken for lasting comfort

A very soft seat can feel comfortable at first. But for regular sitting or sleeping, the upholstery construction, shape retention and frame design also matter. Details such as the type of foam, whether it has a spring core, the frame material and the maximum load should be clearly stated in the product information.

For a sofa with a bed function, it’s also important to check whether the sleeping surface is level throughout. Differences between the seat and back sections may be acceptable for occasional overnight stays, but could become uncomfortable with frequent use.

3. Care instructions are only checked after purchase

An easy-care sofa cover isn’t necessarily removable or machine washable. Check the manufacturer’s specific guidance:

  • Is the cover removable?
  • Can it be washed, or should it only be vacuumed gently?
  • How does the material react to spills?
  • Are replacement covers available?
  • How resistant is the surface to pets and everyday friction?

For delicate bouclé, polyester or chenille covers, avoid harsh cleaning products and direct sunlight if the care instructions recommend doing so.

The key things to consider at a glance

Dimensions and sleeping area

Measure the space where you plan to put the sofa in both configurations. A sofa bed around 190 cm wide may fit well as a sofa, but will need considerably more depth when unfolded. A compact sleeping area is often sufficient for occasional overnight stays. Couples or regular users should also compare the actual width, length and maximum load.

Mechanism and frequency of use

A folding sofa with an adjustable backrest can usually be changed quickly from a seat into a bed or reclined position. Models with metal legs or a sturdy frame can provide extra stability when used as a bed. If you’ll be converting it often, look for a mechanism that’s easy to operate without much effort.

A 3-in-1 sofa can be used as a sofa, lounge chair or bed, depending on the design. Check whether the backrest locks into clearly defined positions and whether there’s enough room to unfold it.

Cover, upholstery and load capacity

The material description alone doesn’t tell you everything about how practical a sofa will be day to day. Compare:

  • Foam, high-density foam or spring core
  • Frame material and legs
  • Maximum load
  • Seat height and depth
  • Cover material and care requirements

An adjustable backrest can be useful for reading, watching TV or relaxing. However, it’s no substitute for checking the seat height, back support and your own comfort needs.

Sofa bed FAQs

How much space does a sofa bed need when unfolded?

As well as the sofa’s width, you’ll need to allow for its extended depth and enough clear space to move around. Measure the distance from tables, cupboards, radiators and doors. If you’re considering a corner sofa with a bed function, make sure the ottoman’s orientation works with your room layout.

How long does a sofa bed last?

Its lifespan depends on the frame, mechanism, upholstery, load and care. A sofa bed used for occasional guests will be put through less wear than one used every day. Check the warranty, maximum load and care instructions, and avoid using it in ways the design isn’t intended for.

Does a sofa bed use electricity?

A manual folding sofa, floor sofa or pull-out sofa doesn’t need electricity to operate. A recliner or electric TV chair with powered adjustments may add to your energy costs. Before buying, check whether a manual or electric mechanism is better suited to how you plan to use it.
