To choose a sofa bed well, decide three things in this order: how it opens, what guests will sleep on and how much space you have when it is fully extended. The mechanism determines how easy it is to use and how much floor it needs. The mattress determines whether guests sleep well. The size determines whether it fits your room and still leaves space to move around.<\/p>\n
Everything else, from colour to leg style, is easier to settle once those foundations are right. You can compare different designs side by side in our range of sofa beds UK sale<\/a>, but the guidance below will help you narrow the field before you start browsing.<\/p>\n A sofa bed in a spare room that welcomes guests a few times a year has very different demands from one in a studio flat that becomes a bed every night. Before looking at mechanisms, be honest about frequency.<\/p>\n For occasional guests, sitting comfort usually matters most, because the sofa will spend far more time as seating. For regular or nightly use, the sleeping surface takes priority, and you should favour designs with a proper mattress rather than cushions that double as a bed. Somewhere in between are home offices and box rooms where the sofa bed is used a few nights a month and needs to do both jobs reasonably well.<\/p>\n It also helps to decide how the sofa bed should look within the room before you narrow down the mechanism. Browsing modern sofas UK sale<\/a> gives a sense of the shapes, arm styles and finishes available, so you can choose a sofa bed that sits comfortably alongside the rest of your furniture.<\/p>\n A click clack sofa bed has a backrest that folds down flat to meet the seat. You lift the seat until it clicks, then lower it so the back drops into a flat position. The seat and back together form the sleeping surface. It is quick, needs no separate mattress and works well in compact rooms because it extends only a little further forward than the sofa itself. The trade off is that guests sleep on upholstery foam rather than a dedicated mattress.<\/p>\n Pull out sofa beds hide a folding metal frame and mattress beneath the seat cushions. You remove the cushions, pull the frame forward and unfold it. These designs look like a conventional sofa when closed and offer a separate sleeping surface, which many guests find more comfortable. They need a good amount of clear floor in front of the sofa when open.<\/p>\n These designs unfold from the front, often in sections, and may use a thick folding mattress. They are usually simple, light and easy to move, which makes them practical for student rooms and small flats.<\/p>\n Larger chaise and corner designs often combine a pull out section with a storage chaise. They suit family living rooms where a large sofa is needed anyway and the bed is an added bonus. They take up more space but can offer a generous sleeping area.<\/p>\n If your chosen design has a separate mattress, it is worth understanding what is inside, and our range of modern mattresses UK<\/a> is a useful reference for how different constructions feel. The main types are:<\/p>\n Depth matters as much as type. A thin mattress allows guests to feel the bars of the frame, while a deeper one smooths them out. We explain the comfort differences in more depth in our article on memory foam mattresses in UK sofa beds<\/a>.<\/p>\n For click clack designs without a separate mattress, look at the seat foam and consider a topper. A good topper turns an adequate surface into a comfortable one and rolls away into a cupboard when not needed.<\/p>\n Sofa beds are described in two ways: by seating capacity and by sleeping size. A two seater sofa bed often opens into a small double or a compact sleeping area, while a three seater usually opens into a double. Some larger and corner designs offer something closer to a king size surface.<\/p>\n Sleeping sizes are not always identical to standard bed sizes, so always check the open dimensions rather than relying on the label. Length is especially important for taller guests, as some compact designs are shorter than a typical double bed.<\/p>\nStart With How the Sofa Bed Will Be Used<\/h3>\n
