Bed Stairs Clearance Guide UK
To manoeuvre a bed or mattress up UK staircases you need at least 70cm of straight clearance on the narrowest tread and 90cm of diagonal turning space on landings for a standard single mattress. King size and super king require 85cm minimum tread clearance and 110cm diagonal space. Always measure twice before ordering.
Why Stair Clearance Matters When Buying a Bed
UK homes often have narrow staircases, especially in terraced houses and older properties built before modern building regulations. A mattress or bed frame that cannot navigate the turn at the half-landing will leave you with an expensive return or disassembly on delivery day. Understanding exact clearance prevents wasted time and cost. Standard UK mattress sizes are small single 75x190cm, single 90x190cm, small double 120x190cm, double 135x190cm, king 150x200cm and super king 180x200cm. EU sizes such as 140x200cm double differ and may need extra room on the diagonal.
Minimum Clearance Measurements for UK Staircases
Measure the narrowest point of each tread (usually the inner edge of a winding stair) and the diagonal distance from the top of one riser to the opposite corner of the landing. For memory foam or pocket sprung mattresses rolled for delivery allow 65-75cm width clearance on straight flights. Unrolled or rigid bed frames need the full mattress width plus 10cm for safe tilting. Landings must offer at least 90cm diagonal for single sizes and 110cm for king sizes to allow the mattress to pivot without catching the banister or wall.
Use a rigid measuring stick or piece of timber cut to the mattress length to simulate the turn. For bunk beds the same rules apply but the dismantled sections are usually shorter. Bunk beds sold in the UK must meet BS EN 747 with the top-bunk guard rail rising at least 16cm above the mattress surface; always use the maximum mattress depth stated by the maker and note that top bunks are not recommended for children under 6.
Checklist Before You Order a Bed or Mattress
- Measure the narrowest tread width at floor level and at head height.
- Measure the diagonal clearance on every landing including headroom from ceiling to stair edge.
- Check for awkward banister spindles, newel posts or radiators that reduce usable space.
- Decide whether the mattress will be rolled (most memory foam and hybrid types) or delivered flat.
- Confirm the bed frame arrives flat-packed with the longest single panel shorter than your tightest clearance.
- Ask a second person to hold the tape while you walk the simulated route.
- Photograph measurements with a tape visible for the delivery team.
If any measurement is below the thresholds above consider a smaller size, a split mattress or a bed frame that can be carried in sections. Mattresses must meet UK fire-safety rules and upholstered furniture follows the 1988 regulations; these do not affect clearance but confirm the product is legal for UK homes.
Clearance Requirements by Mattress and Bed Type
Memory foam mattresses can be rolled tightly for delivery, reducing the effective width needed to around 65cm on straight sections. Pocket sprung models with reinforced edges need more care on turns. For memory foam mattresses choose thinner profiles if your staircase has low headroom. Bunk beds with stairs are popular in children’s rooms but the stair section itself must fit through doorways first. See the range of bunk beds with stairs and measure the longest panel before ordering.
Storage beds and ottoman beds arrive in multiple flat panels but the base sections can still be bulky. Fabric beds and wooden frames from the bed frames collection often have headboards that must be tilted vertically on landings. Always check the product page for exact panel dimensions rather than relying on general advice.
Decision Rules – When to Choose Smaller Sizes or Split Options
If your staircase offers less than 75cm tread clearance, avoid anything larger than a double. For king size beds you need at least 85cm clear width and a landing diagonal of 110cm. Super king is rarely possible in homes with standard 1980s or older stairs unless delivered in two separate mattresses. Consider a split king arrangement using two single mattresses zipped together. Noomi and Maxitex ranges include models suitable for this approach. A Noomi Waterproof Eco Foam Mattress Single paired with another offers flexibility where a single large mattress will not fit.
Children’s rooms often have tighter access. Kids’ beds in single size are easiest to manoeuvre. Wooden children’s beds and storage options from the range usually dismantle into shorter lengths. If buying a bunk bed choose models where the side rails and stairs come in sections no longer than 140cm to match common cot-bed mattress lengths.
Protecting Your Mattress During Manoeuvring
Once you have confirmed clearance, protect the mattress from dirt and snags on banisters. A simple cotton sheet or the plastic wrapper it arrives in can prevent marks. After the mattress is in place a mattress protector guards against future spills, especially useful in children’s rooms with single beds. For extra comfort on top of a firm base, a mattress topper can be added later without affecting stair clearance.
Maxitex offers several children’s options that balance support and ease of handling. The Maxitex Kids Premier Sprung Mattress is popular for single and small double bunk beds because its construction allows gentle flex during tight turns. Similarly the Maxitex Kids Magic Memory Foam Mattress rolls compactly, making it ideal for narrow UK staircases in family homes.
Common Staircase Problems and Practical Fixes
Spiral or winding stairs are the biggest obstacle. Measure the inner radius carefully; anything under 70cm usually rules out king-size mattresses. Low headroom on the upper flight often catches the end of a rigid frame. In these cases choose a fabric bed that folds or a headboard that detaches completely. For homes with very tight access, pre-assembled furniture is rarely suitable; opt for flat-pack from the bedroom furniture range instead.
Older Victorian terraces frequently have a 76cm stair width. This comfortably fits a single when rolled but leaves little margin for a double. Always add 5cm either side for safe handling. If the newel post protrudes, consider temporary removal by a joiner rather than forcing the mattress and risking damage. Remember UK fire regulations require all mattresses to pass BS 7177 testing; clearance is a practical issue, not a legal one, but both must be satisfied.
Finally, involve the delivery team early. Reputable carriers will ask for staircase photos if you flag potential tight access. Taking the time to measure saves disappointment and ensures the bed you choose, whether a practical bunk bed with stairs or a luxurious king-size memory foam model, actually reaches the bedroom.

Frequently asked questions
Can I carry a king size mattress up narrow UK stairs?
A king size mattress needs at least 85cm tread clearance and 110cm diagonal turning space on landings. Many older UK staircases fall short, so measure first. Rolled memory foam versions are easier than rigid pocket sprung types. If clearance is marginal choose two single mattresses instead.
Do bunk beds with stairs require more clearance than normal beds?
The stair unit and side panels are often carried separately so individual pieces may fit where a full frame would not. Top bunks must still meet BS EN 747 with guard rails at least 16cm above the mattress. Top bunks are not recommended for children under 6. Check the longest panel against your tightest stair measurement.
What is the best mattress type for tight staircases?
Memory foam and hybrid mattresses that roll tightly need the least clearance, often 65cm on straight sections. Avoid thick orthopaedic models with rigid edges. Maxitex and Noomi ranges include several rollable options suitable for narrow UK homes. Always confirm rolled diameter on the product page.
Should I measure headroom as well as width?
Yes. Low ceilings on upper flights can stop a long mattress pivoting on the landing. Measure vertical clearance from the top stair tread to the ceiling above the turn. Add at least 10cm to the mattress length for safe tilting. This is especially important for super king and certain ottoman base sections.
Is it worth buying a split mattress for difficult stairs?
Split king or zip-and-link mattresses solve many clearance problems because each half is narrower and shorter. They are easier to manoeuvre and can be zipped together in the room. Noomi and Maxitex offer compatible single models that work well in this configuration while still meeting UK fire safety standards.
