BTHFST Low Loft Bed Twin Size with Storage, White

The measurements

These are the maker's published figures for this piece, converted to centimetres alongside. Measure your own space before ordering: 77.8 by 39.4 inches is the floor it needs, and 41.5 inches is how far up it goes.

Published dimensions describe the assembled piece. Packaging is larger, and a doorway or stairwell has to take the box as well as the finished item.

What it takes out of the room

The piece itself occupies 21.3 square feet. Furniture is not used at its own edge though, so the number that matters is the one with room to stand and open things: allow two feet of clear space on each side and the same piece asks for about 44.8 square feet of the floor plan.

In a ten by ten room, which is 100 square feet, that leaves roughly 55.2 square feet for everything else. At 41.5 inches tall it sits below most window sills, so it can usually go under one.

Our room fit calculator does this arithmetic for any room size you type in.

What it holds

6 drawers. Drawer capacity is not published, so we do not state one.

Our storage arithmetic works out what a given number of drawers actually swallows, using the published sizes across the range.

Safety, and what the rule actually says

This piece's specification names guardrails, an anti-tip device to anchor it to the wall.

Bunk beds are one of the few pieces of furniture with a federal standard behind them. The CPSC publishes the requirements: a bed counts as a bunk bed once the mattress foundation sits more than 30 inches above the floor, the upper bunk needs at least two guardrails with at least one on each side, and guardrail tops must stand at least 5 inches above the top of the mattress. On the open side, the gap between the end of a guardrail and the nearest bed end may be no more than 15 inches.

Those numbers are why mattress thickness matters on a bunk: a thick mattress lifts the sleeping surface and steals the 5 inches the rule asks for.

Follow the manufacturer's instructions, and where a child is involved follow the age guidance printed on the product itself.

Putting it together

This piece arrives flat and is assembled at home. Printed instructions are supplied with it.

The tools needed are included in the box. Bunk and loft frames are built standing up and the upper structure is awkward to hold alone, so a second pair of hands is worth arranging.

We do not publish a build time. The makers in this range do not state one, and a figure invented here would be worth nothing to you. Our assembly guide covers what the specifications across the range do say.
