For most cabins, a bunk bed built around a UK standard single mattress of 90 by 190 cm is the right size. It gives children and most adults enough length to sleep comfortably while keeping the frame compact enough for a small timber room. If the cabin has generous floor space and will host couples or larger adults, a bunk with a small double or double lower bed is worth considering. The more important measurement is usually height: the top sleeper needs room to sit up without touching the ceiling, and in cabins with sloping or low roofs, that often decides which bunk will fit.<\/p>\n
Our range of modern bunk beds UK<\/a> includes standard, low and mixed size designs, and the wider bedroom furniture UK sale<\/a> collection includes compact storage for small sleeping spaces. Below, we explain how to work out the right bunk size for a garden cabin, a holiday lodge or a log cabin bedroom.<\/p>\n Cabins vary far more than ordinary bedrooms. A modern garden room might have straight walls and a flat ceiling. A traditional log cabin often has a pitched roof with low eaves. A holiday lodge might have a small second bedroom designed around two single beds. Before looking at any bunk, record four measurements.<\/p>\n First, the floor length and width of the room, taken at floor level and again at about one metre high if the walls are not straight. Second, the ceiling height at its lowest and highest points. Third, the position and swing of the door. Fourth, the position of windows, heaters and any sockets you need to keep clear.<\/p>\n With these four figures, you can quickly rule out bunks that will not fit and focus on the ones that will.<\/p>\n Most bunk beds sold in the UK are designed for single mattresses on both levels. A standard UK single mattress measures 90 by 190 cm. The frame itself is usually a little larger to allow for the rails, posts and ladder, so expect a footprint of roughly 95 to 100 cm wide and 195 to 205 cm long, depending on the design. Always check the specific product dimensions rather than relying on a general figure.<\/p>\n Some bunks use a small single mattress, around 75 by 190 cm. These are narrower and can be useful in very tight cabins, though they suit children better than adults.<\/p>\n Triple bunks and mixed size bunks, where the lower bed is a small double or double, are also available. These increase sleeping capacity but need more floor width, so they suit larger cabins or lodges where the bunk room is the main bedroom for a family.<\/p>\n In a typical house, ceiling height is rarely a problem for a bunk. In a cabin, it often is. Many timber cabins have pitched roofs, and the space under the eaves can be surprisingly low.<\/p>\n A standard bunk usually stands somewhere between 150 and 170 cm tall. Low bunks are noticeably shorter, which makes them helpful in rooms with limited height. To check whether a bunk will work, take the ceiling height above where the bed will sit and subtract the height of the top mattress surface. The remaining space is the headroom available to the top sleeper.<\/p>\n That headroom should allow the person on the top bunk to sit up without bending their neck. For a child, that is a smaller gap than for an adult. Measure the seated height of the tallest likely user, from the mattress to the top of their head, and make sure there is some clearance above that.<\/p>\n If the cabin has a sloping ceiling, place the bunk so the head end of the top bed sits under the highest part of the roof. Sitting up usually happens at the head end, so that is where the clearance matters most.<\/p>\n Fitting the frame is only part of the job. People need to be able to climb in, change bedding and get dressed without bumping into walls.<\/p>\n Allow clear floor space beside the ladder side of the bunk, wide enough for someone to stand and turn. In practice, this means keeping the area in front of the ladder free of furniture and making sure the door does not swing into it.<\/p>\n Think about how bedding will be changed on the top bunk. If the bed is pushed into a corner with walls on two sides, the open sides need to be reachable. Lightweight duvets and fitted sheets make this easier in a tight cabin.<\/p>\n The mattress is just as important as the frame, and in a bunk it has a safety role as well as a comfort one. The top bunk’s guard rail is designed for a mattress of a particular maximum depth. If the mattress is too deep, the guard rail no longer rises far enough above the sleeper to do its job.<\/p>\n Always check the maximum mattress depth stated for the bunk, then choose accordingly. Our mattresses UK<\/a> range includes single sizes in different depths, so you can match the mattress to the frame.<\/p>\n In cabins that are used seasonally, mattresses need to cope with changes in temperature and humidity. Store spare bedding in sealed bags during the off season and allow mattresses to air when the cabin is opened up again.<\/p>\n A garden cabin used as an occasional guest room has different needs from a holiday lodge that sleeps a family every week in summer. Consider who will sleep there and how often.<\/p>\n For a garden cabin that doubles as a home office or hobby room, a low bunk keeps the room feeling open and leaves wall space above for shelving. For a holiday lodge used by families, a full height bunk in solid wood or sturdy metal will cope with regular use. For cabins that may host adults, look for a frame with a higher weight rating and consider a mixed size design with a wider lower bed.<\/p>\n If you are planning a new garden building, it is worth choosing the bunk and the building together. Our selection of garden cabins and summer houses UK<\/a> includes designs with different roof shapes and internal heights, and comparing those with bunk dimensions early avoids surprises later.<\/p>\n Cabins often have timber walls, which makes a wooden bunk feel at home. Pine and other softwoods suit the rustic character of many log cabins, while painted wood can brighten a darker interior. Metal frames are lighter and slimmer, which can help in very small rooms where every centimetre counts.<\/p>\n In cabins that are not heated all year, choose finishes that tolerate some variation in humidity. Solid wood naturally moves slightly with the seasons, so check bolts at the start of each season and tighten them if needed. Metal frames are less affected by moisture but benefit from a quick wipe to prevent dust building up.<\/p>\n Cabin bedrooms rarely have space for a full wardrobe. Plan storage around the bunk rather than next to it where possible.<\/p>\n Drawers or boxes under the lower bunk are the most efficient option. Hooks on the wall near the door handle coats and bags. A narrow shelf near the top bunk gives somewhere to put a torch, a book or a glass of water. Keep anything fixed to the wall clear of the guard rail.<\/p>\n A small stool or low chest beside the lower bunk can act as both a bedside table and a place to store spare blankets.<\/p>\n The top bunk is not suitable for children under six. Guard rails should be fitted on both sides of the top bunk, even if one side is against a wall, as gaps can open between the wall and the frame. The ladder should be fixed securely and kept clear.<\/p>\n In a cabin, consider lighting for night time trips down the ladder. A small plug in night light or a switch within reach of the top bunk makes moving around safer in an unfamiliar space. If the cabin has an electric heater, keep it well away from the bunk and its bedding.<\/p>\n If ceiling height is limited, our article on ceiling heights in UK homes<\/a> offers useful context for thinking about headroom and lighting in lower rooms.<\/p>\n Choosing a bunk for a cabin comes down to three questions. Does the frame fit the floor with space to move? Does the height leave enough headroom for the top sleeper? Does the mattress size suit the people who will sleep there? Answer those with real measurements, and the right bunk usually becomes clear. When you have your figures ready, you can compare frames and mattresses side by side at Furniture in Fashion<\/a>.<\/p>\n Most UK bunk beds take two single mattresses measuring 90 by 190 cm. The frame is slightly larger, so always check the product dimensions before ordering.<\/p>\n Often, yes. Position the bunk so the head of the top bed sits under the highest point of the roof, and consider a low bunk if headroom is tight.<\/p>\n Some are. Look for frames with a higher weight rating and consider a mixed size design with a wider lower bed for adult guests.<\/p>\n Follow the maximum depth stated by the manufacturer. A mattress that is too deep reduces the effectiveness of the top bunk guard rail.<\/p>\n Choose a finished frame, keep the cabin ventilated, and check bolts at the start of each season, as timber can move slightly with changes in humidity.<\/p>\n","protected":false},"excerpt":{"rendered":" For most cabins, a bunk bed built around a UK standard single mattress of 90 by 190 cm is the right size, giving children and most adults enough length while keeping the frame compact.
