Buying a sofa bed: what really matters when it comes to size, sleeping function and material

A sofa bed combines seating with a guest bed, but its suitability for everyday use can vary considerably depending on its design. A sofa bed can be a practical choice for a small flat, a guest room or a flexible living room – provided its dimensions, mechanism and upholstery suit how you plan to use it.

Many disappointing purchases aren’t down to the price, but to unclear product information. Check these three common pitfalls before you buy:

  • Seat and sleeping area are confused: A sofa may look wide, but offer a much smaller or awkwardly shaped surface when converted into a bed.
  • “Easy to fold out” doesn’t tell you much about the mechanism: What matters is whether the backrest reclines, folds completely flat or the seat pulls out.
  • Material names aren’t a substitute for care instructions: Velvet, chenille, corduroy and linen-look fabrics differ in how they should be cleaned, how well they resist wear and how suitable they are for everyday use. If you have pets or children, a removable cover is especially useful.

What to compare before you buy

1. Dimensions in sofa and bed mode

Measure not only the width of the wall, but also how much depth you’ll need when the sofa is unfolded. A 2-seater sofa bed is often suitable for one person or a couple, while a 3-seater sofa bed offers more seating space. With a corner sofa bed, you’ll also need to consider the position of the chaise section and the route through the room.

Check the following before ordering:

  • Width, depth and height in sofa mode
  • Sleeping area and its orientation
  • Distance from tables, radiators and doors
  • The route through stairwells, hallways and doorways
  • Maximum weight capacity according to the product description

A space-saving sofa doesn’t necessarily have to be small. A folding sofa, for example, can be stored compactly, while a pull-out sofa needs more clear space in front of it.

2. Cushion filling and feel

The upholstery affects whether the furniture is suitable mainly for sitting or can also be used regularly as a guest bed. Commonly listed materials include high-resilience foam, memory foam and sprung interiors. However, these terms alone don’t tell you how comfortable the sofa will actually be. Also check the cushioning thickness, construction and resilience, according to the manufacturer’s information.

A sofa with memory foam can adapt to different pressure points, while a sofa with a sprung interior offers a different feel. If the guest bed will be used frequently, an even sleeping surface and a sturdy frame are more important than promotional claims about comfort.

3. Cover, cleaning and conversion

A chenille sofa has a textured, cosy look, but needs to be cleaned in a way that’s suitable for its fibres. A velvet sofa may be more susceptible to pressure marks and spills. So check:

  • Is the cover removable and machine-washable?
  • What cleaning method does the seller recommend?
  • Are there any hard edges or gaps in the sleeping surface?
  • Can you operate the mechanism without much effort?
  • Does the furniture need several hours to regain its shape after unpacking?

Sofas delivered compressed may need time to recover their shape. Allow for this before putting the furniture under regular use.

How to position and care for your sofa bed

Place the sofa on a level surface and follow the clearances specified by the seller. If you choose a pull-out model, make sure the sleeping area can be fully extended without being blocked by rugs, cables or furniture. Folding models often need less floor space, but may have a lower seat height.

Follow the care instructions provided by the manufacturer. Blot spills as soon as possible. Wash removable covers only as directed on their care labels. If the sofa is foam-filled or vacuum-packed, allow it to expand for the recommended amount of time.

Frequently asked questions about sofa beds

How long does a sofa bed last?

Its lifespan depends on the cushioning, frame, mechanism, load and care. Occasional use as a guest bed puts different demands on the furniture than sleeping on it every day. So check the warranty details, maximum weight capacity and guidance on daily use. You can’t determine a sofa bed’s lifespan from its product type alone.

Is a sofa bed suitable for small rooms?

Yes, as long as you take its dimensions when unfolded into account. Compact 2-seaters, floor sofas and models with adjustable backrests are good options for small rooms. Also measure the route into the room and leave enough space to operate the sleeping function.

What does it cost to run a sofa bed?

There are usually no ongoing energy costs, as the sofa converts mechanically. Possible additional costs include cleaning products, replacement covers or, if needed, spare parts for the mechanism. Models with built-in USB ports may use a small amount of electricity when a device is connected.
