Buying a sofa bed: what to consider for comfort, space and sleeping function

A sofa bed combines a place to sit and a place to sleep in one piece of furniture. It’s particularly practical for small flats, apartments, studios, guest rooms and student halls. However, not every sofa bed will suit every room or household. So, before you buy, don’t focus solely on colour and price.

Common pitfalls when buying a sofa bed

1. Not enough room when the bed is unfolded

A sofa bed may look compact when folded away. But when extended or unfolded, it takes up considerably more space. If you only check the sofa’s external dimensions, you may overlook the room needed to move around it.

So, measure:

• the floor space it takes up in sofa mode,
• the length and width when unfolded,
• the distance from doors, radiators and cupboards,
• the space needed to open, move or reposition the cushions.

For a sofa bed for small rooms, folding models or compact two-seaters are often easier to accommodate than a large corner sofa bed.

2. Vague details about padding and weight capacity

Phrases such as ‘premium comfort’ or ‘extra soft’ reveal little about how a sofa is actually made. Details about the padding, frame and maximum weight capacity are more useful. Depending on its construction, high-density or high-resilience foam may feel different to sit on from soft, very yielding padding.

Also check whether the weight capacity applies to the whole piece of furniture or to each seat. These figures aren’t directly comparable.

3. Underestimating the conversion process in everyday use

A pull-out sofa or sofa bed should be easy to operate without much effort. If you’ll use it regularly, check whether the seat cushions need to be removed, folded over or repositioned. A more involved set-up may matter less in a guest room than in a living room where the bed function is used every day.

Check the product description for:

• the type of conversion mechanism,
• whether tools or assembly are required,
• whether cushions are included,
• whether the covers are removable and can be cleaned in line with the care instructions.

The most important things to consider when buying

Dimensions in sofa and bed mode

A two-seater sofa bed suits smaller living spaces, but the sleeping area varies depending on the design. A low folding sofa may have a lower seat height. That can be practical for some uses, but it won’t suit everyone.

When choosing a sofa with a bed function, don’t judge the sleeping area by its width alone. The height of the sleeping surface, the way the padding is divided and any joins between sections also matter. The requirements may differ for occasional overnight guests and regular use.

Frame and maximum weight capacity

Metal frames, plywood components and combination designs can all have different properties. Ideally, the product description should clearly state the materials used for the frame, cover and filling.

Examples from our selection:

• The vidaXL floor sofa is listed as having a metal frame, polyester fabric and foam filling.
• The vidaXL two-seater model with an adjustable backrest is listed as having a frame made from metal and plywood.
• The compact COMHOMA folding sofa is described as having a metal frame.

Always stay within the maximum weight capacity. For example, the vidaXL floor sofa is listed as supporting 110 kg per seat. The product description for the two-seater sofa with wide armrests gives a maximum capacity of 250 kg for three people. These figures apply to the specific product descriptions and shouldn’t be assumed to apply to other models.

Cover, cleaning and delivery condition

An easy-care cover can make everyday upkeep simpler, but it doesn’t replace regular cleaning. Removable covers can make care easier, provided you follow the manufacturer’s washing instructions. For non-removable fabrics, spot-cleaning with a suitable mild cleaning product is usually best. Soaking the fabric, using bleach or applying harsh cleaners may damage the cover.

Also check how the product is delivered. Some models arrive assembled and only need time to regain their shape after unpacking. Others require assembly according to the instructions. Foam furniture may need to rest for up to 72 hours before it reaches its intended shape.

Sofa bed FAQs

How much space does a sofa bed need?

As well as the product dimensions, allow extra room to unfold it and get around it. The space required depends on the mechanism and sleeping position. In small rooms, the dimensions when fully unfolded are especially important.

Is a sofa bed suitable for everyday use as a bed?

That depends on the padding, sleeping area, frame and how you plan to use it. Many models are described as being intended mainly for guests or temporary sleeping arrangements. Before using one as a permanent bed, check whether the manufacturer explicitly recommends it for this purpose.

How do you clean a sofa bed?

Regular vacuuming removes dust and loose particles. For stains, follow the care instructions for the specific cover. Removable covers should only be washed and dried as directed. Avoid citric acid, bleach and harsh cleaners unless their use is expressly permitted.
