Buying a sofa bed: how to find the right model for your room, everyday life and guests

A sofa bed combines a place to sit with a place to sleep in one piece of furniture. It’s a practical choice for small flats, studios, teenagers’ rooms, guest rooms and living rooms. However, a sofa with a bed function, a sofa bed and a pull-out sofa can differ considerably in sleeping area, mechanism, upholstery and the space they take up.

If you focus only on colour and price, it’s easy to overlook important details. Three common buying pitfalls are:

  • Underestimating the size when unfolded: A sofa may fit in the room when folded up, but block doors, walkways or access to cupboards when extended.
  • Vague claims about “comfort”: Descriptions such as “soft upholstery” tell you little about seat height, mattress thickness, suspension or the actual sleeping area.
  • Not checking the material and care instructions: Velvet and chenille can look luxurious, but need to be cleaned according to their material. If the sofa will be used often, removable covers or clear care instructions are worth looking for.

Measurements and features to check before you buy

1. Measure the sofa and sleeping area

First, note down the available floor space. Three measurements are particularly important:

  1. Sofa width in seating mode
  2. Depth when unfolded
  3. Distance from walls, radiators, doors and furniture

A 2-seater sofa bed is often more compact than a 3-seater sofa bed. A sleeping area of around 180 × 100 cm may be enough for one person. If you regularly accommodate two guests, compare the stated width and length of the sleeping surface carefully with your needs.

With a corner sofa with a bed function, you’ll also need to consider which side the chaise longue is on. Check whether you need the longer section on the left or right, and whether it will remain accessible in your room.

2. Check the mechanism and weight capacity

A sofa bed may have a folding backrest, pull-out sections or seats that fold down. A simple conversion mechanism is useful in everyday life, but it’s still important to check the construction.

Look for:

  • Maximum weight capacity, ideally specified per seat or for the whole sofa
  • The stability of the frame, legs and joints
  • Whether it can be operated without excessive effort
  • Possible pinch points when converting it
  • Delivery condition and any assembly required

Weight capacity isn’t a general measure of quality; it’s a specific limit for use. For example, the vidaXL model, which is 200 cm wide, is rated at 110 kg per seat. The Jahnke CHILLAX POSH has a maximum weight capacity of 320 kg. Choose a model whose stated limits suit how you plan to use it, and don’t exceed them.

3. Compare the upholstery, cover and care instructions

A velvet sofa bed often has a polyester cover and foam upholstery. Velvet can feel soft, but it isn’t automatically suitable for every level of wear. Check the care instructions, especially if you have children or pets at home.

Things to consider include:

  • Cover material, such as 100% polyester
  • Type and thickness of the upholstery
  • Seat height and depth
  • Whether it can be cleaned with a vacuum cleaner or damp cloth
  • Protection from direct sunlight and heat sources
  • Guidance on stains, bleaching and washing

If you’ll regularly use it as a guest bed, it’s also worth checking whether the sleeping area is one continuous surface or made up of several upholstered sections. Folds and joins can affect sleeping comfort.

Assembly, care and everyday use

Once delivered, the furniture should be placed on a level surface. For models that need assembling, it’s best to fit all the screws as instructed, then tighten them evenly. Having a second person to help can make assembling larger sofas easier.

For many polyester covers, regular, gentle vacuuming with a soft brush is enough. Wipe up spills promptly with a slightly damp cloth. Avoid harsh cleaning products, bleach and soaking the fabric, unless the manufacturer’s instructions say otherwise.

If you use the sofa every day and convert it into a bed often, check the joints, legs and frame regularly. Once set up, a sofa bed for guests should leave enough room to move around and should not be placed right next to a heat source or naked flame.

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. Measure the depth of the unfolded sofa and allow enough room for a clear walkway. For a model with a sleeping length of 190 cm, also take the ceiling height and nearby furniture into account.

Is a sofa bed suitable for every night?

Not every model is designed for everyday sleeping. Check the details of the sleeping area, upholstery, suspension and recommended use. Many sofa beds are intended primarily as seating, with the option of occasional use as a guest bed.

How long does a sofa bed last?

Its lifespan depends on the frame, mechanism, upholstery, load and care. It isn’t possible to give a reliable lifespan without consistent conditions of use. Technical specifications, guarantee terms and regular checks of moving parts are more useful indicators.
