Ottoman Storage Bench: UK King & Super King Sizing Guide
Share
If you have a UK king or super king bed, the single number that decides whether an ottoman storage bench looks right at the foot of it is width — not length, and not the “king” label on the product. UK beds are narrower than the American beds most online sizing advice is written for, so a bench sold as “king size” is very often too wide for a UK king. This guide gives you the exact centimetre ranges to aim for, and the measurements to take before you buy.
The short answer: For a UK king bed (mattress 150 cm wide), choose a bench roughly 110–135 cm long. For a UK super king (mattress 180 cm wide), aim for 135–160 cm. As a rule, the bench should span about three-quarters to nine-tenths of the mattress width and should never be wider than the bed frame.
How wide should an end-of-bed bench be for a UK king bed?
A UK king mattress is 150 cm wide and 200 cm long (5ft × 6ft 6in). The bed frame itself usually adds a few centimetres each side, so the visible footboard width tends to sit around 155–165 cm.
The reason width is the deciding measurement is proportion. A bench that runs the full width of the bed reads as a second piece of furniture rather than a finishing detail, and one that is wider than the frame overhangs and looks like a mistake. The established interior rule is that the bench should be narrower than the bed and cover most — but not all — of its width, leaving a small reveal of floor or frame at each end.
For a UK king, a bench of 110–135 cm sits in the sweet spot. Around 120–130 cm is the most reliable choice: it covers roughly four-fifths of the mattress width and leaves a balanced gap at each end. Keep it under about 140 cm so it stays inside the frame footprint.
If your room is tight, a bench at the lower end of that range or one on slim open legs keeps the foot of the bed from feeling boxed in. For more on working benches into smaller rooms, see our guide to ottoman storage benches in small UK flats.
How wide should an end-of-bed bench be for a UK super king bed?
A UK super king mattress is 180 cm wide and 200 cm long (6ft × 6ft 6in) — the same length as a king, but 30 cm wider. That extra width is the whole reason super king bench sizing is different: a bench that looked generous against a king will look undersized here.
For a UK super king, aim for a bench of 135–160 cm, with around 150 cm as the ideal. That spans roughly four-fifths of the 180 cm mattress and holds the proportion. You can go up to about 170 cm if you want the bench to read as a near-full-width statement, provided it still sits within the frame.
Because a super king is the largest standard UK bed, the foot-of-bed space can also carry more depth and presence — this is the one size where a deeper, arm-detailed bench (or even a compact end-of-bed sofa) is in proportion rather than overbearing.
Why are benches labelled “king size” often too wide for a UK king bed?
This is the trap that catches most UK shoppers, and it comes from a genuine difference in bed standards. A US king is about 193 cm wide — far wider than a UK king at 150 cm. Almost all online “end-of-bed bench” sizing advice, and a large share of the listings, are written to that US standard.
So a bench described as “king size” is frequently built at 60–66 inches (about 152–168 cm) to suit a US king. At 152 cm, that bench is already wider than a UK king mattress. Put it at the foot of a UK king and it overhangs the frame at both ends.
A bench marketed as “king size” (typically 60 inches/152 cm and up) is usually sized for a US king — which makes it the right width for a UK super king, not a UK king. For a UK king, the width you actually want is closer to what US sellers call a “queen” bench.
| Sold as (US label) | Typical width | Actually right for (UK) |
|---|---|---|
| “Queen” bench | 50–55 in (127–140 cm) | UK king (150 cm bed) |
| “King” bench | 60–66 in (152–168 cm) | UK super king (180 cm bed) |
The safe habit is to ignore the size name entirely and check the width in centimetres against your own mattress. Every bench in our range is listed in centimetres for exactly this reason.
How wide should the bench be compared with the bed? (quick-reference table)
Both UK king and super king beds are 200 cm long, so length never changes the answer — only the width does. This table is the one to keep.
| UK bed size | Mattress width | Ideal bench length | Maximum (stay within frame) |
|---|---|---|---|
| King | 150 cm (5ft) | 110–135 cm | ~140 cm |
| Super king | 180 cm (6ft) | 135–160 cm | ~170 cm |

How deep can the bench be, and how much walkway do you need?
Width gets the proportion right; depth decides whether you can still move around the bed. At the foot of a king or super king, the bench depth eats into the floor space between the footboard and whatever is opposite — a wall, wardrobe or radiator — and you need a clear walkway left over.
Most end-of-bed ottoman benches are 35–45 cm deep. The practical sum is simple: the floor depth beyond your footboard must be at least the bench depth plus a usable walkway behind it.
| Element | Recommended |
|---|---|
| Bench depth (front to back) | 35–45 cm |
| Walkway behind the bench | At least 60 cm (75–90 cm is comfortable) |
| Total floor depth needed beyond footboard | Bench depth + walkway (e.g. 40 cm + 70 cm = 110 cm) |
Leave at least 60 cm of walkway between the back of the bench and the nearest wall or wardrobe. With a typical 40 cm-deep bench, that means you need roughly 100–110 cm of clear floor beyond the footboard.
One extra check on an ottoman bench specifically: the lid lifts upward on a hinge, so make sure nothing directly above the foot of the bed — low wall art, a sloping ceiling or a window sill — blocks the lid from opening fully.
What seat height works at the foot of a UK king or super king bed?
Height is the detail people forget, and it is what keeps the bench from looming. As a guide, the seat should sit at or just below the top of the mattress. A bench that stands taller than the mattress draws the eye and breaks the line of the bed.
Most end-of-bed ottoman benches are around 45–50 cm tall, which suits the majority of UK divan and framed beds. If you have a low platform bed, choose a lower bench so it still reads as a finishing piece rather than a barrier. Sitting height also matters in practice — this is where you perch to put on shoes, so a seat that lines up with the mattress edge is the most comfortable.
How do you measure your bed before buying?
Five measurements settle it. Take them before you shortlist, not after.
| Step | What to measure | Why it matters |
|---|---|---|
| 1 | Mattress width (confirm 150 vs 180 cm) | Don’t trust the size name — this is the number that sets bench width |
| 2 | External frame / footboard width | The bench must stay inside this; it’s your hard upper limit |
| 3 | Floor depth beyond the footboard | Bench depth plus walkway has to fit inside it |
| 4 | Mattress top height from the floor | Keep the seat at or just below this |
| 5 | Clearance above the foot of the bed | The ottoman lid needs room to open fully |
With those five figures, the choice becomes mechanical: pick a bench that is about 75–90% of your mattress width, fits within the frame, and leaves at least 60 cm of walkway behind it.

Frequently asked questions
What size bench fits the end of a UK king bed?
A UK king mattress is 150 cm wide, so aim for a bench of 110–135 cm long, with around 120–130 cm as the ideal. That covers roughly four-fifths of the mattress width and leaves a balanced reveal at each end, while staying inside the frame.
What size bench fits a UK super king bed?
A UK super king mattress is 180 cm wide, so choose a bench of 135–160 cm long, with about 150 cm as the ideal. You can go up to roughly 170 cm for a near-full-width look, as long as the bench still sits within the bed frame.
Should an end-of-bed bench be the same width as the bed?
No. The bench should be narrower than the bed — about 75–90% of the mattress width — and never wider than the frame. A bench that matches or exceeds the bed width overhangs the frame and looks out of proportion.
Why are US “king size” bed benches too big for a UK king?
A US king is about 193 cm wide, against 150 cm for a UK king. Benches built for a US king are typically 60–66 inches (152–168 cm), which is wider than a UK king mattress. That width actually suits a UK super king, not a UK king.
How much space do I need behind an end-of-bed ottoman bench?
Leave at least 60 cm of walkway between the back of the bench and the nearest wall or wardrobe, with 75–90 cm being more comfortable. With a typical 40 cm-deep bench, that means about 100–110 cm of clear floor beyond the footboard.
