How Big Is a Superking Bed?

A UK super king bed measures 180cm wide by 200cm long, which is 6ft by 6ft 6in. That is 30cm wider than a king and 45cm wider than a standard double, giving each of two sleepers 90cm of space, the same width as a single bed each. It is the largest size sold as standard in the UK.

The frame will add to those figures. Depending on construction, a super king takes up between 184cm and 200cm of floor width once assembled, and the room needs to accommodate that plus clearance on both sides. As a working figure, allow at least 300cm of wall to wall width to place one comfortably.

Super King Compared With Other Sizes

Set against the rest of the UK range the difference is clear. A single is 90cm, a small double 120cm, a double 135cm, a king 150cm and a super king 180cm. Length steps up from 190cm on singles and doubles to 200cm on kings and super kings.

The jump from king to super king is the largest single increase in the standard range. Thirty centimetres is enough to change how the bed is used: couples who currently touch when they turn over will not, and a child or pet joining in the morning stops being a squeeze.

It is worth being clear that the extra space is all width. A super king is the same 200cm length as a king, so if your issue is height rather than shared space, moving up will not help. Anyone over about 6ft 4in should look for an extra long frame instead, which is a separate specification.

Room Sizes That Work

A super king needs a genuinely large bedroom. With a 190cm wide frame and 60cm of comfortable clearance on each side, you are looking at 310cm of width as a minimum for easy access. Reduce clearance to 45cm on both sides and 280cm can work, though the room will feel bed dominated.

Length is easier. Allowing for a headboard and 60cm to walk at the foot of the bed, 270cm of room depth is generally sufficient. Rooms that are long and narrow can sometimes take a super king placed across the shorter wall, provided the door does not open into the walkway.

Typical UK main bedrooms of 3m by 3.5m can take a super king, but with little left over. In that footprint you will fit the bed, two slim bedside cabinets and one further piece of furniture. Full depth wardrobes on the remaining wall will make the room feel crowded, so built in storage or sliding wardrobes UK sale designs that need no door swing are the sensible approach.

Getting a Super King Into the House

Access is the most common problem with this size. A 180cm mattress is wide and, in pocket sprung form, heavy and inflexible. Turning it up a domestic staircase is frequently impossible, particularly where there is a landing turn or a low bulkhead at the top.

Two solutions exist. Zip and link mattresses come as two 90cm halves that join together, and each half handles like a single mattress. Rolled or vacuum packed mattresses compress into a manageable package and expand in the room. Between the two, most access problems can be solved, but you need to choose before ordering rather than after.

Frames are generally delivered flat and built in situ, so they present fewer difficulties. Super king divan bases arrive as two 90cm halves. Measure your narrowest doorway, the stairwell at its tightest point and the turning space on the landing, and check the ceiling height above the stairs while you are there.

Bedding and Accessories

Super king bedding is widely available in the UK but stocked less deeply than king, so choice is narrower and colours sell out sooner. Duvets are typically 260cm by 220cm, and pillowcases are the same 50cm by 90cm king size, usually used in threes or fours across the width.

Fitted sheets need to be 180cm by 200cm with a depth that suits your mattress. Check mattress depth before ordering and allow at least 5cm more on the sheet, plus the depth of any topper. Deep fill sheets are worth the small extra cost on a bed this size, because a sheet that pulls loose on a super king is difficult to reach across and remake.

Throws and blankets need scaling up too. A throw of 240cm by 260cm gives a balanced drop on a super king, where the same throw on a king would trail. Buying king sized accessories for a super king bed is the most frequent sizing mistake with this format.

Furnishing the Rest of the Room

With a bed this wide, the surrounding furniture has to be chosen with restraint. Full width bedside cabinets either side add 90cm or more to the footprint, so narrow designs of 35cm to 40cm keep the proportions workable. Wall mounted shelves save floor entirely, which can be the difference between a room that flows and one that does not. Our modern bedside cabinets UK sale range includes slim options intended for exactly this situation.

Storage often has to move vertically. Taller, narrower chests hold as much as wide low ones while claiming less floor, and a mirrored front helps a bed dominated room feel less closed in. A modern mirrored bedroom furniture UK selection is a practical trick in rooms where the bed takes most of the light.

Resist the temptation to add a chair or a bench unless there is genuine space. A super king already provides the visual weight a bedroom needs, and additional pieces around it tend to narrow walkways rather than improve the room. If you want somewhere to sit or store bedding, a slim modern blanket box UK sale at the foot of the bed does both jobs in one footprint.

Dressing a Bed This Wide

Bedding is where super king ownership costs the most over time. Duvets, sheets and covers all have to be bought in the size specifically, and the ranges available are smaller than for kings and doubles. Sale rails rarely carry super king stock, so buying two sets at the outset saves hunting later.

Pillow arrangement changes at this width. Two standard pillows leave visible gaps at each end of a 180cm mattress, so most people run four pillows across, or two standard pillows with square continental pillows behind them. That reads as deliberate styling rather than an attempt to fill space.

Duvet weight is worth thinking about too. A super king duvet is a substantial item to shake out, and drying one after washing needs either a large machine or a launderette. Two single duvets on one bed is a practical alternative that also solves the problem of couples who prefer different warmth levels.

Throws need to be scaled up in proportion. A throw of roughly 200cm by 220cm sits across the width of a super king with even fall on both sides, while a standard 130cm by 170cm throw looks stranded. Folding a large throw across the foot in a band of around 60cm gives the neatest result on a bed of this scale.

Is a Super King Worth It

For two adults in a large bedroom, the extra width genuinely improves sleep, particularly if one person is restless or you have different bedtimes. It also absorbs the reality of family life: children and pets can join without anyone losing their space.

Against that, a super king reduces flexibility. Bedding costs more and offers less choice. The mattress is difficult to rotate alone. Moving house means checking access at the next property, and the bed may simply not fit. Resale demand is narrower than for kings and doubles.

The honest test is whether your room can take it without sacrificing storage or movement. If a super king means the wardrobe no longer fits, a king with proper storage will serve the room better. If the space is genuinely there, it is the most comfortable standard size available.

Frequently Asked Questions

What are the exact dimensions of a UK super king bed?

A UK super king mattress is 180cm wide and 200cm long, or 6ft by 6ft 6in. Frame width varies by construction and typically brings the total floor width to between 184cm and 200cm.

What size room do I need for a super king?

Around 310cm of wall to wall width allows comfortable access on both sides. You can manage in roughly 280cm with reduced clearance, and about 270cm of room depth covers the headboard plus space to walk at the foot.

Will a super king mattress fit up my stairs?

Often not in one piece. A zip and link mattress splits into two 90cm halves, and a rolled mattress compresses for delivery. Choose one of those options if your stairwell has a turn or a low bulkhead.

Can I use king bedding on a super king bed?

No. A king duvet is 30cm narrower and will not cover the mattress properly, and a king fitted sheet will not stretch to 180cm. Buy bedding made specifically for super king dimensions.

Is a super king better than two singles pushed together?

A super king gives a single continuous sleeping surface with no central ridge, which most couples prefer. Two zip and link singles offer the option of different mattress tensions on each side and easier access up stairs.
