A single sofa bed is defined by its size: it opens into a bed for one person and usually closes to the footprint of an armchair or a compact loveseat. A pocket sprung sofa bed is defined by its mattress: individually wrapped springs that respond to the body independently. The two are not mutually exclusive, but in practice the choice usually comes down to this. If space is your main constraint, a single sofa bed is the sensible answer. If sleeping comfort and regular use matter most, a pocket sprung model, usually in a double size, is the better investment.
Understanding the difference helps you choose the right piece from our modern sofa beds UK sale. Both types sit within our wider sofa furniture UK range, and each suits a particular kind of room and household. Below we look at how they compare on size, comfort, use and placement.
A single sofa bed, sometimes called a chair bed, converts into a sleeping surface roughly the width of a standard single bed. In the UK a standard single mattress is 90cm wide and 190cm long, and single sofa beds are generally designed around similar proportions, though widths vary between models.
When closed, a single sofa bed usually seats one or two people. Many open with a fold out or pull out mechanism, where the seat extends forwards and a mattress section unfolds. Others use a click clack action, where the back folds down flat.
The main appeal is compactness. A single sofa bed can fit into a box room, a study, a landing nook or a corner of a living room where a full sofa would not. It is also a practical choice for a teenager’s room or a small flat where every bit of floor counts.
A pocket sprung sofa bed uses a mattress built around individually wrapped springs. Each spring sits in its own fabric pocket and moves independently. This means the mattress responds to the shape and weight of the person lying on it, rather than sagging as a whole.
Pocket sprung mattresses are common in standard beds and are valued for support, breathability and reduced motion transfer. In a sofa bed, they bring a sleeping experience closer to that of a conventional bed. They are typically found in pull out or fold out designs, where the mattress is stored within the frame, because the springs need a certain depth that click clack designs do not usually accommodate.
Pocket sprung sofa beds are most often available in double or small double sizes, though some compact models exist.
Single sofa beds win clearly on size. They take up less wall space when closed and need less floor space when open. A pocket sprung double sofa bed will generally be wider, deeper and heavier, and the open bed will occupy a larger area.
If you are working with a narrow room or a small box room, measure carefully. A single sofa bed may be the only option that leaves room for a walkway once it is open.
Pocket sprung mattresses generally offer better support for regular sleeping. The independent springs adapt to the body and help keep the spine in a more natural position. They also allow air to circulate, which can make them feel cooler than some foam mattresses.
Single sofa beds vary widely. Many use foam mattresses, which can be entirely comfortable for occasional use. Higher quality single models may use memory foam or deeper foam layers, which mould to the body and soften pressure points.
For a guest who stays a night or two a few times a year, a single sofa bed with a decent foam mattress is usually adequate. For someone who will sleep on the sofa bed several nights a week, or for longer stays, a pocket sprung mattress is worth considering.
Pocket sprung sofa beds tend to be heavier because of the springs and the frame needed to support them. This matters for delivery, particularly in upstairs flats, and for moving the piece around the room. Single sofa beds are usually lighter and easier to reposition.
Single sofa beds often use simple mechanisms that are quick to operate. Pocket sprung sofa beds typically use a pull out mechanism with a folding metal frame. These are straightforward once you are familiar with them, but they involve a few more steps.
A single sofa bed is usually the right fit. It provides a comfortable chair by day and a bed for one by night, and it leaves room for a desk or storage.
If the room has space, a pocket sprung double sofa bed offers a more generous and comfortable bed for couples or regular visitors.
In a living room where the sofa bed is the main seating, a larger pocket sprung model often makes sense. It offers proper sofa seating during the day and a comfortable bed when needed.
In a studio, the sofa bed may be the primary bed. A pocket sprung mattress is strongly worth considering here because of the nightly use.
If a single sofa bed feels too large and you mainly need extra seating, an armchair might be the better choice, with an inflatable or folding mattress stored for rare guests. Our 1 seater fabric sofas UK are worth browsing if you want a compact armchair that fits the same space a single sofa bed would.
That said, a single sofa bed combines both functions in one piece, which is often more convenient than storing a separate mattress.
Whichever type you choose, the mattress is central to comfort. Look at the depth of the mattress, the materials used and whether it can be replaced in future. Some sofa beds allow the mattress to be upgraded, which can extend the useful life of the frame.
If you are considering a separate mattress for a guest room as well, our mattresses UK sale range covers sprung, foam and hybrid options. It is worth knowing that firmness labels vary between manufacturers. Our report on UK mattress firmness labels and how they compare looks at why a medium in one range can feel different from a medium in another. If you are weighing foam against springs specifically, our article on memory foam mattresses in UK sofa beds explains the key differences.
Comfort on the first night is only part of the story. A sofa bed is opened, closed and sat on repeatedly, and its mattress has to recover each time it is folded. Foam mattresses in single sofa beds can gradually soften along the fold lines, particularly if the bed is used more often than intended. Choosing a denser foam helps it hold its shape for longer.
Pocket sprung mattresses tend to keep their support well because the springs carry most of the load. The comfort layers on top can still compress with heavy use, so look for a mattress with a reasonable depth of padding over the springs. Airing the bed now and then and following the manufacturer’s care guidance will help either type last.
It is also worth thinking about how your needs might change. A single sofa bed chosen for a box room may later move into a teenager’s bedroom or a study. A pocket sprung double bought for a guest room might one day become the main bed in a first flat. Choosing a well made frame keeps those options open.
Neither option is better in every situation. A single sofa bed is a clever solution for compact rooms and occasional single guests. A pocket sprung sofa bed delivers more comfort for frequent use and larger rooms. The right choice depends on your space, your guests and how often the bed will be slept in.

Some do, though it is less common. Most single sofa beds use foam mattresses because they are lighter and fold more easily. Check the product details if sprung support matters to you.
Pocket sprung mattresses are generally well suited to regular use because they offer responsive support and good airflow. Many people use them nightly in studio flats.
A single sofa bed. It has a smaller footprint both closed and open, which makes it a practical choice for box rooms and studies.
