About this guide

The steps, the part numbers, the counts and the order come from IKEA's assembly manual AA-2703327-1 (2026-03-24). The outer size, 76.5 × 39 × 76.5 cm, is IKEA's published size. Board thickness, hole positions and the bracket height are read off the drawings, so they are close, not measured. The 3D runs faster than real hands do.

Each shelf holds up to 13 kg and the top up to 25 kg, according to IKEA.

The official instructions are on IKEA's product page (PDF). If something here differs from the manual in your box, follow the manual.
