Choosing a sofa bed: a buying guide for small and large living spaces

A sofa bed gives you somewhere to sit as well as extra sleeping space. It’s a practical choice for guests, small flats, student accommodation or a home office that occasionally doubles as a bedroom. But unclear dimensions, soft cushions that don’t provide enough support and hard-to-use folding mechanisms can all lead to a disappointing purchase.

So before you buy, look beyond colour and price. The key things to consider are the actual sleeping area, how much room the sofa needs when opened out, its weight capacity and how practical the upholstery is for everyday use.

Common pitfalls when buying a sofa bed

1. Only considering the dimensions when the sofa is folded away

An extending sofa needs considerably more room than a standard sofa. Before you buy, measure its maximum depth and width when fully opened. Make sure there’s still enough space to move around and that doors, radiators and windows remain accessible.

With a corner sofa bed, you’ll also need to consider the position of the chaise. Check whether the sleeping area is on the left or right, and whether you can rearrange the furniture if you move home.

2. Mistaking “soft” for comfortably supportive over time

Very soft cushions can feel pleasant to sit on, but may not provide enough support for regular sleeping. Check the details about the upholstery, frame and maximum weight capacity. A sofa bed for occasional overnight guests has different requirements from one you’ll use every day.

3. Letting extra features make up for an impractical design

A sofa bed with a USB port, storage or an adjustable backrest can be useful, but these features should suit the way you plan to use it. A USB port is only helpful if there’s a socket nearby. Storage is handy, but it shouldn’t make the sofa awkward to open.

What to check before you buy

Sleeping area and room layout

Make a note of these three measurements:

  • Sofa dimensions in seating mode to check the floor space it will occupy
  • Sleeping area when fully opened to check the space available for sleeping
  • Clear passage width for delivery and assembly

A 2-seater sofa bed will often fit into a smaller room, but the width of the sleeping area varies by model. A modular sofa may offer more flexibility, but it requires several separate modules and may take longer to arrange.

Frame, upholstery and weight capacity

A metal or wooden frame affects the sofa’s stability and weight. When checking the product details, distinguish between static weight capacity, weight capacity per seat and any stated total weight capacity. These figures don’t necessarily apply in the same way to every sleeping position.

Foam, pocket springs and combinations of the two all have different properties. Higher foam density is a technical specification, but it isn’t the only measure of personal comfort. Seat height, seat depth, backrest angle and the availability of replacement or washable covers also matter.

Upholstery and care

Corduroy, chenille, polyester and velvet differ in feel, abrasion resistance and care requirements. If you have children or pets, removable covers or clear cleaning instructions can be helpful. Also check whether the upholstery can only be spot-cleaned, and bear in mind that the colour may look different in different lighting.

Use, assembly and care

Read the assembly and safety instructions before using the sofa for the first time. Vacuum-packed models may need to be left to air and regain their shape for several hours. If your sofa is delivered in two packages, check that both have arrived.

Follow the care instructions provided by the manufacturer. Regularly remove dust with a suitable attachment and spot-clean stains wherever possible. Heavy furniture should be moved by at least two people. Don’t put excessive weight on the armrests or backrests, and only use the sleeping function as intended.

Sofa bed FAQs

How much space does a sofa bed need when fully opened?

It depends on the mechanism and the size of the sleeping area. Measure the maximum depth and width, including the chaise or pull-out section. Leave enough space to open the bed and keep doors, windows and sockets accessible.

Is a sofa bed suitable for everyday sleeping?

Not every model is designed for regular use. Check the sleeping area, upholstery construction, frame, weight capacity and care instructions. Many sofa beds are intended as an extra sleeping option for guests. If you’ll be using one regularly, take particular care to compare its ergonomic features and the height of the mattress or upholstery.

How much does it cost to use a sofa bed with a USB port?

The sofa itself doesn’t use electricity. You’ll only incur costs from the chargers and devices plugged into it. These depend on the port’s technical specifications, charging output and power adapter. When assembling the sofa, route the cables so they won’t get trapped or become a trip hazard.
