Buying a sofa bed: what to consider when it comes to sleeping space, materials and bed function

A sofa bed combines seating and an extra place to sleep in one piece of furniture. It’s particularly useful in small flats, apartments, guest rooms and student accommodation. At the same time, models can vary considerably in their sleeping area, seat height, cushioning, weight capacity and construction.

If you’re looking to buy a sofa bed, don’t be swayed by claims such as ‘3-in-1’, ‘ergonomic’ or ‘extra soft’ alone. What matters is having clear product information and knowing how you’ll actually use the sofa: occasionally as a guest bed, every day for sitting, or regularly as a place to sleep.

Common sofa bed buying pitfalls

1. Underestimating the sleeping area

A sofa may look compact when folded, but take up considerably more space when extended. As well as the sleeping area itself, you’ll need to allow room to move around and leave space between the sofa and cupboards, radiators or doors.

Before you buy, check:

  • The sofa’s dimensions in seating and bed mode
  • The width and length of the sleeping area
  • The position of the armrests, backrest and pull-out mechanism
  • The clear space in front of the sofa
  • The route in through doorways, stairwells and lifts

A 2-seater sofa bed is often a good fit for smaller rooms. A corner sofa bed offers more seating, but usually takes up more floor space permanently.

2. Mistaking ‘soft’ for lasting comfort

Very soft cushioning may feel pleasant when you try it briefly, but that doesn’t necessarily mean it will provide the right support for sitting or lying down for longer periods. Details about the cushioning, foam density, springs, frame and seat height are more useful.

With a sofa bed, it’s also worth checking whether the seat cushions simply fold down, pull out or need to be removed completely. A complicated conversion can become a hassle in everyday life, particularly if you regularly switch the sofa between seating and sleeping.

3. Missing material and weight capacity information

Terms such as velvet, corduroy or chenille describe the upholstery fabric, but that’s only part of the picture. Care instructions, abrasion resistance, frame material and maximum weight capacity are also important when choosing a sofa.

Look for specific details about:

  • Upholstery material and cleaning recommendations
  • Whether the frame is made from metal, engineered wood or solid wood
  • Maximum weight capacity per seat or overall
  • Included cushions and accessories
  • Assembly requirements and number of packages
  • Delivery condition and any settling time needed after unpacking

Always consider a high weight capacity in relation to the construction and intended use. The sofa isn’t designed for jumping or climbing.

Key things to consider when buying

Sleeping area and mechanism

A pull-out sofa or folding sofa can be a flexible option for occasional overnight stays. Check whether the sleeping area is flat all the way across and whether the mechanism uses castors, hinges or loose cushions.

A sofa bed for guests should be easy to convert without requiring much effort. If you plan to use it regularly, it’s also important to check whether the construction is designed for daily folding and unfolding or occasional overnight stays.

Cushioning and frame

Foam, high-density foam, memory foam and spring systems all have different properties. Foam can provide an even feel when sitting, while springs can offer structural support in the seating area. How suitable each option is depends on the construction, material thickness and your personal preference.

Don’t judge claims such as ‘high-density’ or ‘heavy-duty’ in isolation. Look for additional details about seat height, cushioning thickness, the frame and the weight limit.

Size, storage and assembly

A sofa bed with storage can hold bedding, blankets or cushions. This can be especially useful in a small flat. However, check whether you can still access the storage when the sleeping area is extended.

With a modular sofa, individual sections can be arranged in different ways to suit your room layout. Check which side the chaise is on, the overall width and whether the modules need to be connected.

Sofa bed FAQs

How much space does a sofa bed need when extended?

Measure the sleeping area and allow enough extra room to move around in front of it. With a corner sofa, you’ll also need to account for the depth of the chaise and nearby walkways. Make sure doors and drawers can still be opened when the bed is set up.

How long does a sofa bed last?

Its lifespan depends on how often it’s used, as well as the frame, cushioning, mechanism and care. A sofa used for occasional guests will have different demands placed on it from one used as a bed every day. Check the screws, hinges, castors and any visible damage regularly. Always refer to the manufacturer’s information and guarantee terms.

Is a sofa bed suitable for every night?

Not every sofa with a bed function is designed to replace a bed permanently. Check whether the manufacturer says it’s suitable for regular use, whether the sleeping area is flat and whether the dimensions and cushioning meet your needs. For occasional overnight stays, a folding sofa, pull-out sofa or compact sofa bed for guests may also be suitable.
