The BRIMNES TV unit, black, 70 7/8x16 1/8x20 7/8 " averages 1 hour and 35 minutes based on 2 real builds, with a moderate difficulty rating.

⏱ Time Breakdown
Estimated split based on how real builds typically run
What usually slows people down
- !Door and hinge alignment — IKEA hinges have 3-axis adjustment, and getting every door flush takes patient iteration
- !Soft-close mechanism installation — it needs to be tensioned correctly to avoid slamming or not catching
- !Getting the carcass level before doors go on — a crooked cabinet makes all door adjustments harder
🛠 How to Assemble It Faster
- 1Get the carcass level before doors go on — a crooked cabinet makes door alignment effectively impossible, not just harder.
- 2Hang all doors before loading the cabinet. Weight changes carcass geometry slightly and affects door swing.
- 3Adjust hinges in order: vertical position first, then depth, then lateral. Doing it out of order means redoing earlier adjustments.
- 4Use a long-shaft screwdriver for recessed hinges — short screwdrivers don't give enough torque and strip the heads.
Drawer Assembly Tip
What speeds things up: Instead of completing each drawer individually, treat the process like an assembly line. Install the slide rails on one side of every drawer box first, then flip them all and do the other side. You'll work faster and everything stays more consistent.
Step-by-Step Assembly Guide
- 1Build the base cabinet carcass completely before adding any doors or drawers.
- 2Install any fixed shelves and verify they're level before proceeding.
- 3Attach door hinges to the cabinet body first, then hang doors and adjust in all axes.
- 4Install soft-close hardware if included. Adjust tension to match each door's weight.
- 5Add any drawers or pull-out baskets, testing each one fully before moving to the next.
- 6Install handles or knobs as the final step.
