ᐅ What is the recommended screw tightening sequence for the Ikea PLATSA system?

Hello everyone,

I am currently assembling an Ikea Platsa wall unit and want to make sure I tighten the screws in the correct order. It is important to me that the furniture is stable and that no deformations occur later on. I understand that with this type of furniture it usually makes sense to initially tighten all screws loosely and then fully tighten them afterward, but I am specifically wondering if there is a recommended sequence for PLATSA – for example, tightening screws on the sides first, then top/bottom, or maybe from the inside out.

Does anyone have a tried-and-tested tip for the screw tightening order when assembling PLATSA? Or are there any guidelines from Ikea that go beyond the general instruction manual? I would appreciate any concrete recommendations or experiences, as I want to approach the assembly carefully and correctly to achieve the best possible stability. Thanks!

As a general rule with PLATSA, as with many flat-pack furniture items, I recommend first screwing all the screws in just lightly, meaning the right amount of tension—not too tight, so nothing warps. After that, tighten them gradually.

In general, it is best to fix the screws on the load-bearing vertical parts first (the connections of the side panels and back panels). Then you can move on to the shelves and the upper/connecting crossbars.

It is important to install screw caps or covers only at the very end, so adjustments can still be made. Tightening from the inside to the outside works well with PLATSA, as this helps align the furniture optimally.

If you have a torque screwdriver, you can fasten the screws with moderate torque to avoid putting stress on the material, but PLATSA is fairly forgiving regarding slight differences in screw tightness.

In short:
- First, screw all screws in hand-tight only
- Then fix the side panels (vertical connections)
- Afterwards, the crossbars and shelves
- From inside to outside

I hope this helps! If you like, I can also explain about cam dowels and concealed hinges, if those are relevant for your piece.

Exactly. Always start by tightening by hand, then systematically tighten, but not in a random order. First the sides, then the center. This prevents stress and ensures stability.

I find this recommendation sensible but somewhat too general. The question arises whether rigidly tightening the screws in this sequence might cause tension if you don’t continuously check the angles or verify the squareness of the furniture in between.

Therefore, I would suggest, in addition to hand-tightening, using a staged process with initially loose fastening of all connections, followed by precision checking, and finally tightening fully. The sequence makes sense, but without measuring tools or markings on the assembly plan, it may not prevent distortions if the furniture is already slightly out of square.

In short: the sequence is important, but in my opinion, visual or measured inspection is also necessary to ensure that PLATSA remains stable and free of stress.

I would like to add an empirically supported recommendation to the previous tips:

- When tightening the screws in the PLATSA system, start with the lower corner screws of the side panels. These usually bear the greatest load, and a solid base prevents later deformation.
- Next, tighten the upper side of the side panels to ensure an even bonding or connection of the parts.
- Then tighten the screws on the back panels to establish the rigidity of the carcass.
- Shelf boards and connecting braces are installed as the final step.

Important: Always tighten the screws in multiple stages to avoid material distortion. If possible, use a torque limiter, ideally between 1.5 and 2 Nm, because PLATSA has visible chipboard edges that can be damaged if over-tightened.

This method is based on an analysis of furniture assembly standards and the particular characteristics of the PLATSA material (chipboard with lacquered edges). This ensures long-lasting stability.

That’s a very good point. Especially with larger PLATSA wall units, it’s worth checking the angles with a spirit level or protractor before tightening any screws.

I usually use a combination of manual checks and gradually tightening, then checking again. This prevents slight deformations since the material is somewhat flexible.

I can only agree with that – you should never tighten with full force at once. The screw holes are pre-drilled, but especially in particleboard, too much pressure can cause the material to break. Overall: patience pays off.
