A super king bed in the UK is 180cm x 200cm, or 6ft by 6ft 6in. That makes it the largest standard size sold in Britain, covering 3.6 square metres of floor before you add the frame. Each of two sleepers gets 90cm of width, which is exactly the width of a standard single mattress.<\/p>\n
Size on paper is only half the story. What determines whether a super king works is the space around it, the route to get it upstairs and how the rest of the bedroom then functions.<\/p>\n
The mattress is 180cm wide and 200cm long, with depth ranging from 20cm on simpler models to over 30cm on deep pocket sprung and hybrid designs. Weight is significant: a pocket sprung super king mattress can exceed 50kg, making it a two person lift.<\/p>\n
The frame adds to every dimension. Upholstered designs with padded side rails commonly add 10cm to 20cm of width, giving an external footprint of 190cm to 200cm. A headboard and footboard add 15cm to 25cm of length, so 215cm to 225cm externally.<\/p>\n
Against the rest of the UK range, a super king is 30cm wider than a king, 45cm wider than a double and twice the width of a single. Length matches the king and double at 200cm, so the size difference is entirely in the width.<\/p>\n
A super king needs its footprint plus walkways. Allow 60cm to 75cm of clear floor on any side you use, which is enough to walk past comfortably and to make a bed without shuffling sideways.<\/p>\n
For access on both long sides plus the foot, the arithmetic gives roughly 340cm of width and 300cm of depth. That is a generous main bedroom, the kind found in larger semis, detached houses and converted lofts with a decent span.<\/p>\n
Where the room is narrower, pushing one long side against a wall brings the requirement down to around 265cm of width. It works, though one sleeper then has to climb over the other, which is fine for some households and unacceptable for others.<\/p>\n
The details that catch people out are always the same: inward opening doors need their full arc, radiators reduce width at skirting level, and chimney breasts narrow the span at one point. Measure at the tightest point rather than the widest, and mark the 180cm x 200cm footprint on the floor with tape before committing.<\/p>\n
Delivery access is where super king plans most often fail. Frames arrive flat packed in several boxes and go up most stairs without trouble. Mattresses are the problem, because a traditional sprung super king mattress arrives as one rigid 180cm slab.<\/p>\n
Measure the narrowest point of your route: the front door, the tightest stair turn, the landing width for pivoting and the bedroom doorway. A 180cm mattress needs a landing wide enough to swing it through, which many Victorian terraces and flats simply do not have.<\/p>\n
Two solutions exist. Rolled mattresses arrive compressed and vacuum packed, then expand over a day or two once unwrapped. These fit through almost any access. Alternatively, zip and link mattresses split into two 90cm halves that zip together on the bed, which also lets each sleeper choose their own firmness.<\/p>\n
Assembly is worth planning for too. A super king frame usually needs two people and around an hour. Look for bolted joints rather than cam fixings on a bed this size, since bolts can be retightened if the frame develops a creak over time.<\/p>\n
At 180cm wide, the frame is the dominant object in almost any bedroom, so its visual weight matters as much as its dimensions.<\/p>\n
Fabric upholstery softens the presence of a large bed and absorbs sound, which helps in rooms with hard flooring. A tall padded headboard gives a focal point in a room without a fireplace or bay. Our modern super king size fabric beds UK sale<\/a> range includes both low profile and statement headboard designs.<\/p>\n Wood suits period properties and rooms with natural materials elsewhere, and it tends to be the quietest option over years of use. Our super king size wooden beds UK sale<\/a> collection covers oak, walnut and painted finishes.<\/p>\n Leather frames hold a crisp architectural line and wipe clean, which suits households where the bed sees daytime use. Metal frames are the slimmest in profile and lightest to move.<\/p>\n Ottoman bases turn the full 180cm x 200cm area into one storage cavity, which is genuinely transformative in a house without loft access. The base needs clearance at the foot to swing up, so allow for that in the layout.<\/p>\n Once a super king is in place, wall space becomes scarce. A 180cm bed plus two 45cm cabinets needs 270cm of wall, which not every bedroom has on its main run.<\/p>\n Narrow cabinets of 35cm to 40cm are the practical answer, or wall mounted shelves where floor standing units will not fit. Match the top height to the finished mattress top so a lamp switch is within easy reach. Our modern bedside cabinets UK sale<\/a> range lists heights for each design.<\/p>\n Clothing storage usually needs rethinking. A tall chest holds the same volume as a wide low one on less wall, and our chest of drawers UK sale<\/a> collection includes upright designs for exactly this.<\/p>\n Wardrobe doors are the final conflict. Hinged doors need up to 60cm of clear floor in front, which is often the same walkway the bed has left you. Sliding doors remove the problem, and our modern sliding wardrobes UK sale<\/a> range is worth comparing where a super king dominates the plan.<\/p>\n Bedding is the last practical point. Super king linen is a distinct size: fitted sheets for 180cm x 200cm and duvets typically 260cm x 220cm. King bedding will not stretch, so buy at least two sets from the start.<\/p>\nFurnishing Around a Super King<\/h3>\n
