Choosing a sofa bed: what to consider for comfort, size and everyday use

A sofa bed combines seating and somewhere to sleep in a single piece of furniture. It’s particularly useful for single people, couples, students and families, as well as anyone living in a small flat or apartment. However, models can vary considerably in sleeping area, cushioning, conversion mechanism and storage.

If you focus only on colour or a low price, it’s easy to overlook important details. The right sofa bed should not only fit your room, but also suit the way you plan to use it.

Common problems when buying a sofa bed

1. Underestimating the size of the sleeping area

A pull-out or folding sofa can look compact when folded away. What matters, though, is its size when set up as a bed. Some models are better suited to occasional overnight guests, while others offer a larger sleeping area for two people.

Before you buy, check:

  • What are the width and length of the sleeping area?
  • Is there enough room to unfold it?
  • Can you still access doors, cupboards and radiators?
  • Will the sofa stand on a stable, level surface?

2. A ‘bed function’ doesn’t guarantee the same level of comfort

A sofa bed can be converted by folding down the backrest, moving the seat cushions or pulling out an additional section. These mechanisms vary in how easy they are to use. Seat and sleeping heights can also differ considerably.

For example, a low-profile model may have a sleeping height of just 13 cm. This could work well in a guest room or for occasional overnight stays, but it won’t offer the same height as a traditional bed.

3. Overlooking the weight limit and frame

Soft cushioning tells you little about how a sofa is built. For everyday use, the frame material, maximum weight capacity and stability all matter. Figures such as ‘up to 280 kg’ should always be considered in relation to the specific product and how it is intended to be used. The weight capacity of a 2-seater sofa bed may also be listed per seat.

Look for specific details from the manufacturer rather than general marketing claims. The same goes for assembly: make sure the screws, legs, joints and backrest are all fitted securely.

The key things to consider when buying

Dimensions as a sofa and as a bed

Start by measuring the space available. Then compare the dimensions in both configurations. For example, a model measuring 180 × 89 × 78 cm as a sofa may need 180 × 105 × 38 cm when set up as a bed. A larger daybed may need a floor area of around 213 × 98 × 70,5 cm.

You should also leave room to move in front of the sofa. This is more important with a pull-out model than with one that converts by folding the backrest backwards.

Conversion mechanism and how often you’ll use it

If you’ll be converting the sofa frequently, look for a mechanism that’s easy to operate. A 3-in-1 sofa with several backrest positions can be used as a seat, lounger or bed. Check that each position locks securely into place and that converting it doesn’t take too much effort.

For occasional guests, a simple design with movable seat cushions may be enough. If you’ll use the sofa regularly for sleeping, also look for an even sleeping surface and suitable mattress or cushion dimensions.

Cover, cleaning and storage

Polyester velvet can feel soft, but it needs to be cared for appropriately. For models where this is specified, regular vacuuming and spot cleaning with a mild cleaning product are recommended. Soaking the fabric, using bleach or applying harsh cleaners can damage the cover.

A sofa bed with storage is handy in a small flat. Check that the storage space is easy to access and large enough for bedding, blankets or cushions. Side pockets are useful for smaller items, but they’re no substitute for a large storage compartment.

Frequently asked questions about sofa beds

How much space does a sofa bed need when unfolded?

It depends on the mechanism and the size of the sleeping area. Folding models usually need room for the backrest to recline or lie flat. Pull-out sofas, on the other hand, need clear space in front of the furniture. Measure the sofa, bed position and surrounding area before you order.

How long does a sofa bed last?

There’s no single answer. It depends on how often it’s used, the frame and cushioning, the weight it supports, how well it’s cared for and how frequently it’s converted. Check the joints, screws, legs and cover regularly. If you notice tears, loose connections or unstable parts, stop using the furniture.

Does a sofa bed use electricity?

A standard sofa bed doesn’t need electricity. Models with a USB-C port or built-in reading light only need power for these extra features. Running costs depend on how often you use them and the power consumption of any connected devices. Without electronic features, the bed function itself doesn’t use electricity.
