About the Thornbury

The Thornbury sleeps three. A full UK double on the bottom, with room for two children to share or for a parent to lie down and settle a younger one at bedtime, and a standard single on top. It's pine, painted white, with slatted end panels and clean straight lines, so it sits easily in a shared room, a guest room or a house that needs somewhere for everyone to sleep at Christmas.

At 148cm high it's lower than most bunk beds, which suits rooms with lower or sloping ceilings and makes the top bunk less of a climb. The angled ladder is fixed at the end of the top bunk, and the top bunk has full-length guard rails on both sides. Both levels have slatted bases, so there's no divan or box spring to buy, and there's about 23cm under the bottom bunk for storage boxes.

It takes two mattresses. The top bunk takes a UK single, 90cm by 190cm, and its guard rail is designed around a mattress no deeper than 15cm. That figure is a safety measurement, not a suggestion: a deeper mattress raises the sleeping surface and leaves less rail above it. The bottom bunk takes a UK double, 135cm by 190cm, and isn't raised, so it can take a deeper mattress if you prefer. The mattresses shown above are matched to both levels.

The Thornbury arrives flat-packed for self-assembly. It's a two-person build, so allow a couple of hours. If you'd rather someone else did it, there's a link to book a local assembler below the returns policy. Delivery is free on a weekday you choose in your basket.

Room fit

At 148cm high, the Thornbury suits rooms with lower or sloping ceilings. Allow about 70cm between the top mattress and the ceiling for a younger child to sit up, and 80 to 90cm for a teenager. It needs about 199cm by 146cm of floor space, with the ladder at the end of the bed rather than the side.

Questions parents ask

Can two children share the bottom bunk?
Yes. The bottom bunk is a full UK double, 135cm by 190cm, with room for two children to share or for a parent to lie down at bedtime.

Will it fit under a sloping ceiling?
It's 148cm high, lower than most bunk beds. Measure from the floor to the lowest point of the ceiling over the top bunk and allow room to sit up, as in Room fit above. Send us your measurements if you're not sure.

Do I need a box spring or divan?
No. Both levels have slatted bases, so you only need the two mattresses.

Can the bottom bunk take a deeper mattress?
Yes. The depth limit is there for the guard rails on the top bunk. The bottom bunk isn't raised, so a deeper mattress is fine if you'd like more comfort, though it does take a little headroom from the space under the top bunk.

Is there room for storage underneath?
There's about 23cm between the floor and the bottom of the side rail, enough for low underbed storage boxes.
