IKEA Assembly Tips: 10 Things Professionals Know That You Don't

If you have assembled one IKEA piece, you have assembled them all — sort of. IKEA uses the same dozen hardware components across almost all their furniture, and once you know the tricks, a 4-hour first-timer build becomes a 45-minute pro build.

Here are the ten things we know from assembling 500+ IKEA pieces that would have saved you a ton of time and frustration.

1. Read the instructions all the way through first

This sounds obvious and 95% of people skip it. Do not.

IKEA instructions are intentionally designed to be sequential and often require you to insert a screw before attaching a piece that would otherwise block access. If you do step 12 without knowing what step 14 requires, you will back up and redo step 12.

Spend 2 minutes flipping through the whole booklet before you pick up a single screw. It saves 15 minutes.

2. Lay out every piece of hardware before starting

Empty the hardware bag into a divided tray (a muffin tin works). Count each type against the hardware list on the first page of the instructions.

If anything is short, stop. Call IKEA. Do not start the assembly with missing parts — IKEA will ship you the replacement for free, usually within 3–5 days.

Common shortages: small wooden dowels (they fall out of the bag in shipping) and the specific wood screws for drawers (IKEA sometimes packages them separately).

3. The right screwdriver matters more than a drill

Every IKEA newbie immediately reaches for their cordless drill. Then they strip the first cam screw they touch.

The truth: most IKEA assembly is done faster and better with a manual screwdriver. Cam screws (those brass barrels that lock panels together) should be tightened by feel — a drill has no feel and will over-tighten, strip the cam, or crack the particleboard.

What to use:

• Ratcheting screwdriver for speed (Klein or Wera makes good ones)
• Manual Phillips #2 for cam screws — always
• Small drill with clutch set to 1 or 2 for wood screws in the back panels

4. The hidden trick for cam locks

Cam locks (the brass barrels with a Phillips slot) only work if the cam screw on the adjacent panel is inserted the right depth. Too deep and the cam cannot grab; too shallow and it grabs with no bite.

The trick: Insert the cam screw until the head is flush with the panel, then back it out 1/2 turn. That is the sweet spot. When you rotate the cam lock to tighten, it will pull the screw in tight and lock the joint.

Pros learn this by feel in about three assemblies.

5. Always assemble on the floor, not a table

IKEA particleboard is flexible. On a table, pieces sag in the middle while you are fastening the edges, and you get a slightly warped final product.

On the floor, pressure is even and the final assembly is square. Use a blanket or cardboard under the pieces to protect the finish from the floor.

6. PAX wardrobes have one step that must not be skipped

PAX wardrobes are our most-built piece. There is one detail the instructions gloss over that is critical.

After you assemble the frame and stand it up, level the entire unit before installing doors. The adjustable feet are there for a reason. If the unit is not level, the doors will drag, sag, or refuse to close.

Use a bubble level on the top of the frame, adjust the feet with an included Allen key, then attach the doors last.

7. Drawers — the cam screws go in a specific direction

IKEA drawer hardware (MALM, HEMNES, many others) includes metal drawer-side rails. These rails have four screw holes — two on the front, two on the back.

The back screws go in upside down compared to what you would expect. The instructions do show this, but the illustration is ambiguous and 50% of first-timers install them right-side up. The drawer will still work, but it will rattle and eventually loosen.

Check the illustration carefully. When in doubt, the cam screw head should point toward the drawer front, not away.

8. The Allen wrench is disposable

IKEA includes a tiny Allen wrench with most furniture. It is made of cheese metal and the head will strip after 5–10 cam screws if you apply any real torque.

Solution: Buy a proper T-handle Allen wrench set for $15 at Harbor Freight. Every time you assemble IKEA, use your T-handle set instead of the included wrench. You will tighten cam screws in half the time and never strip one.

9. Glue the back panel — every time

Most IKEA furniture has a thin fiberboard back panel that slides into grooves on the sides. The instructions tell you to nail it with the supplied pin nails.

Pro move: Before nailing the back panel, put a thin bead of wood glue along the groove. The glue adds significant rigidity to the entire unit and prevents the back panel from rattling or popping out later.

This is the single biggest upgrade to MALM dressers, especially the 6-drawer model which is known to wobble without this step.

10. Anchor everything taller than 30 inches

Every tall IKEA piece comes with a wall-anchor kit (a small metal bracket and screw). People throw these in a drawer and forget them.

Do not skip the anchor. Tall IKEA furniture is top-heavy and tips easily, especially if you have kids or pets. The California IKEA wall anchor law exists because of actual injuries.

Installation is 2 minutes: find a stud on the wall behind the piece, screw the bracket to the stud, and the strap clips to the top of the furniture. Done.

Bonus: the piece we refuse to assemble without a helper

The IKEA PAX double-door wardrobe with sliding doors. Do not attempt this alone. The sliding door rail assembly requires two people holding the frame square while the third hand (yours) threads the rail. Solo, you will be holding the entire frame upright while trying to operate a screwdriver, and the wardrobe will rack and bind.

Every other piece can be assembled solo. For PAX sliders, get help or call a pro.

When to just call someone

DIY assembly makes sense for small to medium IKEA pieces — nightstands, shelves, basic dressers. The math breaks down for:

• PAX wardrobe systems (anything over 80 inches wide): Way too much work solo
• KALLAX with inserts: Easy to assemble, exhausting to load
• MALM 6-drawer dresser: Known wobble issues without professional glue-up
• BESTÅ media units: Lots of small parts and a drilling template that takes time

Our flat rate for most IKEA pieces is $79–$199 depending on size, wall anchor included, packaging hauled away. If it takes you 3 hours and a headache, the pro rate starts to look reasonable.
