Most UK ottoman beds have a gas-strut mechanism rated for the weight of a standard mattress plus roughly 30–50kg of stored contents — and the storage compartment holds around 300–500 litres depending on bed size. The practical limit is rarely weight; it is how easily the platform lifts once loaded.

How much can you actually store?
The compartment spans the full bed footprint at roughly 25–30cm deep. In everyday terms:
| Bed size | Approx. storage volume | Roughly equivalent to |
|---|---|---|
| Single | ~250 litres | 4–5 large storage boxes |
| Double | ~380 litres | 7–8 large storage boxes |
| King | ~440 litres | 8–9 large storage boxes |
| Super king | ~520 litres | 10–11 large storage boxes |
These are indicative figures based on typical UK ottoman dimensions — check the specification on individual product pages for exact internal measurements.
Weight limits explained
Two separate limits apply. The sleeping capacity of the platform and frame is high — our frames are built for two adults plus a mattress with a substantial safety margin. The lifting capacity of the gas struts is the practical constraint: struts are calibrated for the mattress weight they expect, and heavy stored items add to what they must raise.
Overloading rarely breaks anything outright; it makes the platform heavy to lift and, over time, shortens strut life.
Why mattress weight matters most
A heavy mattress consumes most of the strut's assistance before you have stored anything. This is why we recommend medium-weight mattresses on ottoman frames — full reasoning in our mattress pairing guide. If the platform already feels heavy empty, reduce stored weight rather than fighting it.
Getting the most from the space
- Heavy items at the hinge end — nearest the pivot means less leverage working against you.
- Vacuum-pack bedding — duvets compress to a third of their volume, tripling usable capacity.
- Use soft-sided bags, not rigid crates — they conform to the space and cannot jam the platform.
- Keep the perimeter clear — items pressed to the edges are what stop a platform closing flush.

How much weight can an ottoman bed hold?
The frame supports two adults and a mattress comfortably; the gas struts typically assist with the mattress plus around 30–50kg of stored contents.
Can you store heavy items under an ottoman bed?
Yes, within reason — place heavier items at the hinge end and avoid loading so much that the platform becomes hard to lift.
How many litres is an ottoman bed?
Roughly 250 litres (single) to 520 litres (super king).
Will storing things damage the mechanism?
Not at sensible loads. Consistent overloading shortens strut life — our 5-year warranty covers the mechanism in normal use.
