Assembling flat-pack furniture is rarely anyone’s idea of a good time, but a few smart habits can turn a two-hour frustration session into a 45-minute tidy job. I’ve put together everything from cheap nightstands to heavy wardrobes, and these are the exact tricks I use to speed things up without stripping a single screw.

Clear Your Workspace and Lay Out All Parts
In most cases, Before you even open the instruction booklet, give yourself room to work. A cleared floor space of at least six by six feet is ideal for most medium-sized pieces like dressers or desks. If you are working in a hallway or a small apartment, move to the largest room you have—kitchen floors are often the best spot because they are flat and well-lit.

From real-world use, Empty every box completely. Sort the panels by size and shape, standing them against a wall rather than stacking them flat. This saves you from digging through cardboard every time you need a specific board. I also separate the hardware into small bowls or lids—one for cam locks, one for screws, one for dowels. Knowing exactly what you have before you start prevents the dreaded “missing part” panic, and if something is actually missing, you find out early instead of halfway through step four, in my experience.
Read the Manual Once, Then Follow It Step by Step
Honestly, Skipping the manual to save time is the biggest mistake you can make. Skim the entire thing first to spot any steps that require two people or special tools. Then, go back and follow it literally, one step at a time. Do not jump ahead to “get a feel” for the assembly—flat-pack furniture is designed to go together in a specific order, and reversing a step is always slower than just doing it right the first time.
Pay special attention to the orientation of cam locks and dowels. The little arrows on cam locks need to point toward the pilot hole they lock into, and dowels need to sit flush. A quick visual check before tightening saves you from having to pry apart a panel that’s already snug.
Use the Right Tools—and Skip the Allen Wrench
The little L-shaped Allen wrench included in the box works, but it is painfully slow and hard on your hands. Swap it for a ratcheting screwdriver with hex bits or a simple hex key set with a T-handle. A T-handle gives you better grip and more torque, which means faster turning and fewer stripped heads. I keep a DEWALT 27-Piece Hex Key Set around for this exact purpose—it costs about $12 and has every size you will ever need.
You also want a Phillips-head screwdriver or bit for the occasional cross-head screw, plus a rubber mallet. The mallet is for tapping dowels and cam locks into place gently. A regular hammer works, but it can dent the particleboard, so rubber is safer. If you do not have a mallet, use a block of wood as a buffer between the hammer and the panel, honestly.
For screws, a cordless drill with a clutch set to low torque is a game-changer. Set the clutch to 1 or 2 so the drill stops before it strips the hole. Drive the screw most of the way in with the drill, then finish the last turn by hand to feel the resistance. This method is about three times faster than hand-driving every screw, and I have assembled a full IKEA Malm dresser in under 40 minutes this way.
Tighten Cam Locks in the Right Order
Cam locks are the little round metal pieces that join two panels together. The trick is to hand-tighten them first, then go back and fully tighten them only after the entire frame is assembled. If you tighten each cam lock completely as you go, the panels can shift and misalign, making it nearly impossible to fit the last few pieces.
Here is the order I use for a typical cabinet or dresser:
- Attach the side panels to the bottom panel, hand-tightening the cams.
- Slide in any fixed shelves, hand-tightening as you go.
- Attach the top panel, hand-tightening.
- Fit the back panel or backing board—this is often a thin sheet of hardboard that needs to be nailed or screwed in.
- Once everything is square, go around and fully tighten every cam lock with a quarter turn.
This method takes a little discipline, but it prevents the “one panel is crooked” problem that forces you to loosen everything and start over.
Get a Second Person for Large or Awkward Pieces
For anything over 30 inches tall, like a wardrobe or a tall bookshelf, a second person saves more time than any tool. Holding a heavy side panel upright while you try to thread a cam lock is a slow, frustrating dance. With a helper, one person holds the panel steady while the other drives the screws and locks the cams.
If you are assembling alone, use a couple of heavy books or a stack of paint cans to prop panels in place temporarily. This is a hack I use for headboards and long dressers—it keeps the piece from tipping over while I work on the opposite side. Just make sure the props are stable and cannot slide out from under the panel, in practice.
Keep the Hardware Organized and Use a Magnet Tray
Losing a screw mid-project is a guaranteed 10-minute delay. I use a magnetic parts tray, like the Neodymium Magnetic Wristband for small screws, and a simple metal baking tray for the rest. The baking tray is a cheap trick—just place all the hardware on it, and the raised edges keep everything from rolling off the table.
If you are assembling multiple pieces of furniture in one day, label the trays by item. A strip of painter’s tape and a marker does the job. This is especially useful when you are building a full bedroom set, where the screws for the nightstand look identical to the ones for the dresser but are actually different lengths.
Speed Up with the Right Surface Protection
A soft floor covering, like a yoga mat or a folded blanket, is not just for protecting the floor. It also protects the furniture panels from scratches while you slide them around. I have seen more than one brand-new tabletop get ruined by being dragged across a concrete or tile floor. A $5 fleece blanket from a discount store is worth it, and you can wash it afterward.
Also, use a small felt pad or a piece of cardboard under any panel you are working on. This keeps the finish intact and makes it easier to rotate the panel without sliding it awkwardly. It is a tiny step that saves you from having to touch up scratches or, worse, return a damaged piece, in my experience.
The Bottom Line
Flat-pack furniture does not have to eat your whole afternoon. The biggest wins come from preparation: clear space, sorted parts, and the right tools. A decent hex key set and a drill with a clutch will cut your time in half. Tighten cams in the right order, and do not be afraid to call in a friend for the big stuff. Stick to these habits, and you will be done before the coffee gets cold.
Frequently Asked Questions
How do I avoid stripping screws in flat-pack furniture?
Set your drill to a low clutch setting, like 1 or 2, and finish the last turn by hand. This lets you feel the resistance and stop before the screw head chews up the hole. If a screw starts to strip, back it out and try a slightly larger screw or a wooden toothpick in the hole to give it more grip.
Is it faster to use a drill or a screwdriver?
A drill with a clutch is significantly faster, roughly three to four times quicker than a manual screwdriver for a full dresser. The key is keeping the clutch low to avoid over-tightening. For cam locks, use the hex bit attachment on the drill, but hand-tighten them first and finish with a quarter turn, in my experience.
What should I do if a part is missing or damaged?
Stop assembly immediately and check the entire box twice—missing parts are often stuck in the cardboard folds or under the instruction booklet. If it is truly missing, contact the manufacturer’s customer service with the part number from the manual. Most brands ship replacement parts free within a week, and it is always better to wait than to assemble a piece with a compromised panel.
