Buying a sofa bed: what to consider for size, comfort and functionality

A sofa bed combines seating with an extra place to sleep. In a small flat, guest room, student accommodation or living room, a sofa with a bed function can serve several purposes. However, models vary considerably in sleeping area, upholstery, storage and assembly.

If you focus only on colour or a low price, it’s easy to overlook important details. Three common buying pitfalls are particularly worth bearing in mind:

  • “Pull-out” doesn’t automatically mean comfortable: Some sofas do have a bed function, but may have an uneven sleeping surface or very thin upholstery.
  • The overall dimensions are often misjudged: A corner sofa bed can take up considerably more space than you might expect from the product photos. You’ll also need to allow for the extended sleeping area and the space in front of it.
  • Assembly and delivery requirements aren’t always clear: Larger models may arrive in several packages and need assembling. A more compact sofa bed that requires no assembly can be more practical for rented homes or frequent moves.

The key things to consider when buying a sofa bed

1. Dimensions in seating and sleeping mode

Don’t just compare the sofa’s width, height and depth. Also measure:

  • the sleeping area when unfolded or pulled out,
  • the distance to coffee tables, radiators and doors,
  • the space needed for back or seat cushions,
  • the width of the stairwell, hallway and front door.

A 2-seater sofa bed will often fit into smaller rooms. An L-shaped sofa offers more seating, but takes up considerably more space, with dimensions of, for example, 282 × 153 × 85 cm. For smaller spaces, a 160 cm lounge or floor sofa could also be an alternative.

2. Assessing upholstery and sleeping comfort

Descriptions such as “high-density foam” should be backed up with specific details. Check for:

  • the type and density of foam, if provided by the seller,
  • the thickness of the seat and back cushions,
  • any gaps between individual upholstered sections,
  • sprung or pocket-sprung support,
  • the maximum weight capacity of the model.

Thick foam upholstery can help create a comfortable seat, but it doesn’t necessarily tell you whether the sofa will suit your personal sleeping preferences. A sofa with pocket springs may distribute pressure differently from a foam-only model. If you’ll be sleeping on it regularly, check the manufacturer’s guidance on using it as a bed particularly carefully. Many sofa beds are intended primarily for occasional overnight guests.

3. Covers, cleaning and storage

Corduroy, velvet, woven fabric and microfibre all feel different and have different care requirements. Check whether the cover is removable and what cleaning method is recommended. In homes with children or pets, wipe-clean surfaces and durable fabric specifications can be useful, but they’re no substitute for specific care instructions.

A sofa with storage can hold blankets, cushions or bedding. The storage should be easy to access and shouldn’t interfere with the sofa’s function. If you’re considering a movable footstool or ottoman, also check whether it can be used as a side table, a footrest or part of the sleeping area.

Assembly, care and realistic use

Before assembly, check that all the parts are included. If your model arrives in several packages, it’s a good idea to check all the boxes before you start putting it together. Keep the screws, fittings and instructions to hand. A pull-out sofa also needs enough clear space so that the mechanism and upholstery don’t bump into other furniture.

New materials may have a slight smell for a while after assembly or unpacking. Good ventilation will help air them out. Follow the manufacturer’s care instructions; harsh cleaning products can affect fabrics and colours. Plump up the seat and back cushions regularly, and avoid putting sustained pressure on one spot.

Frequently asked questions about sofa beds

Is a sofa bed suitable for every night?

It depends on the design, sleeping area and upholstery. Many models are intended as an extra place for guests to sleep or for occasional use. If you plan to sleep on it every day, look specifically for a model designed for regular use, with an as-flat-as-possible surface and suitable guidance from the manufacturer.

How much space does a sofa bed need?

As well as the overall dimensions, allow for its extended depth or width. With a corner sofa, you’ll also need to account for the length of each section. Measure doorways and hallways, and check the distance to other furniture too, so that delivery and everyday use are hassle-free.

How long does a sofa bed last?

Its lifespan depends on factors such as the frame, upholstery, weight load, frequency of use and care. Don’t exceed the stated weight limit. Removable covers, sturdy frames and replaceable or refillable cushions can help extend its practical lifespan, but this varies from model to model.
