How to Choose a Sofa Bed

A sofa by day, a bed by night. A thoughtfully designed sofa bed brings together comfort, practicality and style, making it a welcome addition to homes where space needs to work a little harder.

What size sofa bed do I need?

When choosing a sofa bed, it's important to consider both its seating capacity and the space it provides for sleeping. A compact design may be ideal for occasional guests, while a larger sofa bed offers more room for two people to sleep comfortably.

Remember that seating dimensions and sleeping dimensions aren't necessarily the same. Always check the measurements of your chosen design in both positions.

Single sofa beds

Ideal for compact living spaces, home offices and occasional overnight guests, a single sofa bed offers a practical sleeping solution without taking up the space of a traditional bed.

The Tilt Sofa Bed is a clever example. Designed with adjustable arms that fold flat, it transforms from a contemporary sofa into a single bed, with pocket-sprung support for sitting and sleeping.

King-size sofa beds

Where space allows, a king-size sofa bed offers more generous sleeping proportions without the need for a permanent bed.

How do sofa beds work?

Modern sofa beds use different mechanisms to transform from seating into a sleeping surface. The best choice depends on how often you'll use the bed, the space available and how easily you'd like it to convert.

Some designs feature adjustable arms or backs that fold flat, while others use a pull-out or hinged mechanism to create a larger sleeping area.

The Tilt Sofa Bed, for example, uses a click-clack mechanism with adjustable arms, while the Oswald Sofa Bed features automatically extending legs. The Marla and Dante designs offer pull-out or fold-out sleeping solutions.

Whichever design you choose, look for a mechanism that's straightforward to operate and suits the way you intend to use your sofa bed.

Are sofa beds comfortable to sleep on?

A well-designed sofa bed should offer comfort whether you're sitting down with a book or settling in for the night. Much of this comes down to the quality of its cushioning, support and construction.

Pocket springs can help distribute weight evenly, while supportive foam layers contribute to a comfortable sleeping surface.

The Otto Sofa Bed, for example, features pocket-sprung seating and back support, transforming into a king-size sleeping surface through a hinged mechanism.

For a design created with regular sleeping in mind, the Multy First Sofa Bed by Ligne Roset combines supportive foam cushioning with a sprung birch slat base.

Top tip: If possible, try your chosen sofa bed in both its seating and sleeping positions. Comfort is personal, and what feels right for one person may not suit another.

How to measure for a sofa bed

Unlike a traditional sofa, a sofa bed needs to fit comfortably into your room in two different configurations. Before choosing, measure the space available for both seating and sleeping.

  • Measure the width and depth of the sofa bed in its closed position.

  • Check its fully extended dimensions and allow enough room to operate the mechanism.

  • Consider surrounding furniture, including coffee tables, side tables and floor lamps, which may need to be moved when the bed is in use.

  • Check access routes, including doorways, hallways and staircases, to ensure your chosen sofa bed can be delivered into your home.

Top tip: Mark out the open and closed dimensions on the floor using masking tape. It's a simple way to see how the sofa bed will work within your space.

What upholstery should I choose for a sofa bed?

The right upholstery should complement your interior while being practical for the way you use your sofa bed.

Textured fabrics and soft weaves can bring warmth and character to a living space, while more durable upholstery options may be better suited to frequently used seating.

If your sofa bed will be used regularly, consider how the fabric feels, how easily it can be maintained and whether removable covers are available.

For designs with a choice of upholstery, we recommend ordering fabric swatches to see the colours and textures in your own home before making your decision.
