Metal Bunk Bed Twin Over Twin

About this piece

Two beds in one footprint, which is the whole argument for a bunk in a small room. Assembled it measures 41 in wide by 77.5 in deep by 63 in high.

It is built from steel frame, 22 slats across the deck. What it holds: 12.2 in of clearance underneath.

Guard rails on the upper deck stand 11.2 in above the sleeping surface, and rail height is measured from the top of the mattress rather than from the deck.

The rest of the specification: anti-tip hardware is in the box and the instructions call for it to be fitted, the slat bearings are damped, which is where bed noise comes from and no box spring is needed.

Every bed page here states the three numbers that decide how a frame lives: slat spacing, total weight capacity and the clearance under the frame. Slat spacing matters most, because a mattress warranty usually requires slats no more than about three inches apart, and a frame that fails that quietly voids the mattress rather than the frame. The rest of the room is on bedroom, and how to choose a size is worked through in The Bed Frame Guide: Slats, Storage and Why Beds Squeak.

Sizes, load ratings and what fits what are stated the same way across iPormis bedroom furniture, so two pages can be compared without opening either box.
