Buying a sofa bed: how to find a space-saving model for sitting and sleeping

A sofa bed has to serve several purposes in everyday life: it’s a seat, a place to stretch out and, sometimes, a guest bed. Combining a sofa and a bed is especially practical in small flats, student accommodation and guest rooms. But attractive product photos and general marketing claims don’t automatically help you choose the right one.

Before you buy, look out for these three common pitfalls:

• Unclear bed function: Some models only recline partway, or offer a sleeping area that’s much smaller than expected when unfolded.
• Unsuitable dimensions: A sofa may look compact when folded away, but need considerably more room when extended.
• Unexplained weight capacity: Maximum load figures often refer to the whole structure. Make sure the sofa is suitable for the number of people using it and for how you plan to use it.

Key things to consider when choosing a sofa bed

1. Dimensions as a sofa and as a bed

Don’t just measure the available wall space. Check:

• Depth and height in sofa mode
• Length and width of the sleeping area
• Distance from tables, radiators, doors and cupboards
• Space in front of the sofa for moving around
• The route in through the stairwell, doors and lift

For example, a fold-out sofa bed that’s 180 cm wide may need more depth in bed mode than the product photo suggests. With a pull-out sofa bed, also check that the castors, handles and pull-out sections will be easy to reach.

2. Mechanism and adjustability

The design determines how easy the sofa is to convert in everyday use. Common types include:

• Fold-down mechanism: The backrest folds backwards. This is often straightforward with a 3-in-1 sofa bed.
• Pull-out function: An extra section pulls out towards the front.
• Modular design: Individual sections can be joined to create a larger sleeping area.
• Daybed design: The sofa can be used as a bed all the time, with cushions making it comfortable as a seat.

Look for specific details about the positions available. For example, the COMHOMA model is listed as having six backrest positions and reclining from 90 to 180 degrees. Other models specify fixed angles or stepless adjustment. These details are more useful for reading, watching TV or sleeping than general claims such as ‘multifunctional’.

3. Upholstery, cover and weight capacity

Foam, memory foam, springs and frame materials all affect comfort and shape retention. Look for product descriptions that give specific details, such as:

• Type and density of the foam
• Cover material
• Removable or wipe-clean parts
• Frame material
• Maximum weight capacity

Corduroy, velvet and linen differ in feel, care requirements and appearance. An easy-care cover can be a good choice for families with children or pets. However, a high weight capacity doesn’t tell you whether the sofa is suitable for sleeping on regularly, occasional guests or simply relaxing.

Check assembly, care and everyday practicality

For a sofa bed, how it’s delivered can affect both cost and the time it takes to set up. Some models arrive ready assembled, while others come in two packages and need tools to put together. Be sure to check:

1. Whether delivery is to your flat or only to your front door.
2. Whether multiple packages might arrive at different times.
3. How long the cushions take to regain their shape after unpacking.
4. Whether the covers are removable or can only be cleaned with a damp cloth.
5. Whether spare parts, care instructions and assembly instructions are available.

If you plan to use it as a bed every night, a separate mattress topper may be worth considering, provided the design and sleeping height allow for one. For occasional overnight stays in a guest room, a simpler fold-down or pull-out mechanism is often enough. A sofa bed for a guest room should be quick to convert and easy to access.

Frequently asked questions about sofa beds

How much space does a sofa bed need when unfolded?

It depends on the mechanism and the product dimensions. Measure the sofa depth, then add the extra space needed for the pull-out or fold-down section. Allow room to move around too, so the bed isn’t right up against furniture or doors.

Is a sofa bed suitable for every night?

Not every model is designed for everyday use. Look for a flat sleeping surface, sufficient width, a sturdy base and specific guidance from the manufacturer on how it should be used. A sofa bed for occasional guests has different requirements from one used as a permanent bed.

How long does a sofa bed last?

Its lifespan depends on the mechanism, upholstery, cover quality, load and care. Converting it frequently puts more strain on the joints and pull-out sections than using it mainly as a sofa. Clean the cover according to the care instructions and avoid putting the structure under excessive strain for long periods.
