Bunk Bed

Product

Overview

The bunk bed stacks two single beds to free floor space, putting one sleeping deck above another on a shared structure. Two matching bed frames, the Upper Bed Frame and Lower Bed Frame, span between two End Panel units that are tied together by four Corner Post corner posts. The upper deck is guarded by Guard Rail boards, reached by a hook-on Ladder, and braced against sway by Anti-Rack Brace diagonals.

Each deck rests on a Slat Roll rather than a box spring, and the whole bed is knock-down: it ships flat and bolts together with the Assembly Hardware kit. The design follows bunk-bed safety standards that govern guard-rail height, the gap below the rail, and the spacing between structural members.

How it works

Load from each sleeper passes into a Slat Roll, laminated-plywood slats linked by webbing, which sits on ledger cleats inside the Upper Bed Frame or Lower Bed Frame. The frame rails carry that load to the four Corner Post posts, and the End Panel head and foot panels lock the posts into a rigid box. Because a tall, narrow frame wants to lean, the Anti-Rack Brace diagonals triangulate the structure so it cannot rack side to side.

The joints are the safety-critical part. The Assembly Hardware kit uses long hex bolts that thread into cross-dowel barrel nuts seated in the posts, giving a strong end-grain joint, while cam locks pull the panels tight. On the upper deck, Guard Rail boards bolt to brackets on both long sides so the rail rises well above the mattress and the gap beneath it stays small. The Ladder hooks over the upper side rail and its anti-slip rungs are tenoned between two stiles. Tightening every bolt after assembly, and re-checking them periodically, is what keeps the bed from loosening under repeated movement.
