Step 1~90 min total
Count and sort all hardware before touching anything
Open every hardware bag and count the cam bolts, cam bolt nuts, dowels, shelf pins, and wall anchor screws against the parts list on page 2 of the manual. IKEA's packing accuracy is around 95% — someone gets short-changed every twentieth wardrobe. Finding a missing cam bolt after you have the frame half-assembled is not a situation you want to be in. If anything is missing, IKEA will mail replacements free — but that takes a week.
