A super king bed is the largest standard size available in the UK, and for couples who have made the decision to invest in maximum sleeping space, it changes things noticeably. At 180 x 200cm, it gives each person approximately 90cm of personal space -- roughly equivalent to a full single bed width each. At Land of Beds, we stock over 400 super king beds across every style: premium fabric frames, wooden bedsteads, ottoman storage bases, divan sets, and zip-and-link compatible options for couples who need different mattress tensions on each side. Free mainland UK delivery, a Price Promise Guarantee, and honest advice from people who know this category properly come as standard.

Most people buying a super king bed have made the size decision. The room takes it, they want the space, and they are not going backwards. What they are working through is whether to go with a single base or a zip-and-link configuration, which type suits the room and storage needs, and which construction gives the best long-term value at this size. At Land of Beds, we've been helping couples work through exactly this for over 50 years, with honest advice and no pressure to buy.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Single base or zip-and-link | A zip-and-link is two separate bases joined together, allowing two people to have different mattresses on each side. At super king size this option is more widely available and more commonly needed than at any other size, because couples buying super kings often have meaningful weight or preference differences between them. | Whether both partners sleep comfortably at the same mattress tension; the weight difference between partners; whether a zip-and-link configuration is worth the additional cost |
| Room fit | A super king needs proper clearance to work in a room. At 180cm wide and 200cm long, a minimum room width of 4m is the practical guide for 60cm clearance on each side. Too tight and the size advantage is lost in a cramped layout -- the room has to work around the bed every day. | Room width (ideally 4m or above), clearance on both sides, whether the full room layout functions properly with a super king |
| Type and frame quality | A super king in a main bedroom is a significant investment. The type determines how storage works and how the base supports the mattress over years of daily use by two people. At this size the frame also becomes a more prominent visual feature simply because it fills more of the room. | Whether storage is needed and which type, base quality relative to the mattress being paired, whether the frame design works at this scale |
A standard UK super king bed measures 180 x 200cm (6ft x 6ft 6in). It is the largest standard bed size available in the UK.
| Dimension | Measurement | Notes |
|---|---|---|
| Width | 180cm (6ft) | Gives two adults approximately 90cm each -- roughly equivalent to a full single bed width per person |
| Length | 200cm (6ft 6in) | The same length as a king size. Suits sleepers up to approximately 6ft 3in. |
| Zip-and-link width | 2 x 90cm joined | Each base is single-sized; joined they form the full 180cm super king surface |
| Minimum room width | Approximately 4m | With 60cm clearance on each accessible side and at the foot |
A super king gives each partner approximately 90cm of personal space -- similar to a full single bed each. For couples where one or both are restless sleepers, this significantly reduces how much each person's movement reaches the other side.

Our recommendation
Choose a super king if: your room is 4m wide or more, partner disturbance has been a persistent problem, or both partners have significantly different sleep needs (zip-and-link).
Stay with a king if: the room is under 4m wide -- in rooms below this threshold, a king gives a better overall result because the bedroom stays liveable every day, not just when sleeping.
Dr Nerina Ramlakhan, Land of Beds' resident sleep physiologist: couples frequently normalise sleep disturbance for years without realising it is fixable. The assumption becomes that this is just what sharing a bed feels like. In many cases it is not. For couples where one person moves a lot, runs hot, or has a disrupted sleep pattern, a super king -- particularly with a zip-and-link configuration for different tensions -- is often the first setup that genuinely resolves the problem rather than simply managing it.
| Type | Key Features | Best For |
|---|---|---|
| Ottoman | Gas-lift mechanism opens entire base upward; exceptionally high capacity at this footprint; no side clearance needed | Maximum storage in a large bedroom -- the super king footprint makes this the highest-capacity storage option available |
| Divan | Solid upholstered base; lower profile; optional integrated drawers | Practical, lower-profile setups -- often the most cost-effective choice at super king size |
| Fabric / Upholstered | Statement padded headboard; wide fabric and colour range | Bedrooms where the bed is the dominant design feature -- at super king the headboard becomes a genuine statement piece |
| Wooden | Solid or engineered wood; warm finish; durable construction | Long-term everyday use, classic or natural interiors -- adapts better to redecorating than fixed fabric finishes |
| Zip-and-link compatible | Two separate bases joined; each accepts an independent mattress of a different tension | Couples with significantly different body weights, sleep positions, or firmness preferences |

A zip-and-link configuration joins two separate single bases to form one super king surface. Each base takes an independent mattress, allowing each partner to choose a completely different tension or construction.
| Zip-and-Link Factor | Detail |
|---|---|
| What it allows | Each person chooses their own tension: soft on one side, firm on the other, for example |
| When it matters most | When two partners have a weight difference of 25kg or more, or significantly different sleep positions |
| Base compatibility | Not all super king bases are zip-and-link compatible -- always confirm before ordering a base |
| Mattress size | Each mattress is 90 x 200cm -- 10cm longer than a standard single (90 x 190cm). Must be ordered as a super king single, not a standard single. |
| The gap question | A well-fitted zip-and-link will not have a noticeable gap in normal sleeping use |
If you are considering zip-and-link, speak to our team before ordering -- base compatibility varies and this is one of the more nuanced decisions in this category.
| Storage Type | Capacity | What to Check |
|---|---|---|
| Ottoman | Exceptional -- the entire super king footprint; no side clearance needed | Gas-lift weight limit -- check against your chosen mattress weight. Some models require a minimum mattress weight. |
| Side drawers | Medium -- easy daily access | Allow 60cm of clearance on the opening side -- at super king width, confirm this against both sides of the room layout |
| End drawers | Medium to large | Allow clearance at the foot of the bed |
| No storage | None -- widest frame style choice | Under-bed storage boxes supplement well if needed |
| Budget | What You Get | Best For |
|---|---|---|
| Under £700 | Entry-level super king frames -- limited style and storage choice | Budget-conscious buyers or rooms where the bed is functional rather than a visual feature |
| £700 to £1,200 | Better materials, wider storage and style options. Where most main bedroom buyers start. | Everyday main bedroom use -- the entry point for quality at this size |
| £1,200 to £1,800 | Improved build quality, natural materials, longer-lasting construction. Where most main bedroom buyers land. | Everyday use in a main bedroom -- durability over years of daily use by two people |
| £1,800 and above | Premium and luxury construction -- solid hardwood, high-end fabric, extended lifespan | Statement bedrooms; long-term investment where quality is the priority |
A super king is a significant purchase. Buying one step below what you need and replacing it in five years is consistently more expensive than buying correctly the first time.

| Question | Answer |
|---|---|
| What size is a super king bed in the UK? | A standard UK super king bed measures 180cm wide by 200cm long (6ft x 6ft 6in). This is the largest standard bed size available in the UK -- 30cm wider than a king and 45cm wider than a double. For two adults sharing, it gives each person approximately 90cm of personal space, roughly equivalent to a full single bed width each. |
| Is a super king worth it over a king? | For couples who share a bed every night and prioritise sleep quality, yes -- if the room is at least 4m wide. The extra 30cm over a king gives each person 90cm, which is enough to make partner disturbance significantly rarer. Customers who move to a super king and have the room for it consistently say that sleep disruption they had normalised for years stops affecting them. In rooms under 4m wide, a king gives a better overall result because the bedroom stays practical to live in. |
| What room size do I need for a super king bed? | At least 4m x 4m gives comfortable clearance on each side and at the foot, following the 60cm clearance rule. Some customers manage in rooms closer to 3.8m wide with careful furniture planning, but it is worth a short conversation with our team before ordering. |
| What is a zip-and-link super king bed? | A zip-and-link joins two separate single bases to form one 180cm super king surface. Each base takes an independent mattress, allowing each partner a different tension. Particularly useful when two partners have a weight difference of 25kg or more, different sleep positions, or where one has a health condition requiring a specific firmness. Not all super king bases are compatible -- always confirm before ordering. One important note: zip-and-link mattresses are 90 x 200cm, not the standard single size of 90 x 190cm. Always order the correct length. |
| Is fabric or wood better for a super king frame? | At super king size, the frame makes a stronger visual statement because it fills more of the room. Fabric frames -- velvet and linen in neutral tones in particular -- create a warmer, hotel-like feel and are currently the most popular choice at this size. Wooden frames adapt better to redecorating over time. If you are decorating around the bed for the long term, fabric can be worth the commitment. If you prefer a material that adapts to change, solid wood is the better choice. |
| What mattress fits a super king bed? | A standard super king takes a 180 x 200cm mattress, sometimes listed as a 6ft mattress. Zip-and-link configurations take two 90 x 200cm mattresses -- note these are 10cm longer than a standard single (90 x 190cm) and must be ordered as super king singles. Land of Beds stocks super king mattresses separately and as part of divan sets. |
| Ottoman or drawers for a super king? | At super king size, ottoman holds considerably more than drawers because the footprint is the largest available. If storage capacity is the priority, ottoman wins. Drawers are better for daily access to regularly used items. One practical consideration: drawer beds need 60cm of clearance on the opening side. At super king width, confirm this is available on both sides of the room before choosing a drawer configuration. |
| Do you offer free delivery on super king beds? | Yes. All super king beds come with free delivery to mainland UK addresses, no minimum spend. Professional bed assembly and old bed removal and recycling are both available as add-on services. |
| Can I buy a super king bed on finance? | Yes. Finance is available on eligible orders with repayment terms from 3 to 48 months. See our finance page for eligibility and how to apply. |
