Hello everyone,

About six months ago, I bought an IKEA KALLAX shelf and only recently noticed that the back panel is starting to come loose in several places. The back panel is made of a thin particleboard, which originally seemed to be properly attached. Now it can be easily lifted and feels generally unstable.

My question is: Has anyone experienced the back panel of the KALLAX shelf coming loose after a few months? What is the best way to fix it without damaging the shelf’s structure or leaving unsightly holes? Are there recommended methods or tools that can help with reattaching it?

I would appreciate any practical tips or personal experiences!

Here is a brief guide for reattaching the KALLAX back panel:

1. Carefully remove the back panel.
2. Check the frame for any damage.
3. Use small wood screws (about 3-4 mm in diameter, 15-20 mm in length (0.12-0.16 inches diameter, 0.6-0.8 inches length)), pre-drilled!
4. Place screws every 10-15 cm (4-6 inches) to evenly distribute tension.
5. If you prefer not to use screws, small furniture nails are an alternative, but they are less durable.

When installing, make sure the back panel lies flat to avoid warping. Remove any excess material with sandpaper.

Good luck!

to work with wood adhesive based on assembly glue

I can confirm that wood glue combined with small nails is a very practical solution. The wood glue ensures a strong, lasting bond, while the nails hold everything in place during drying.

Just be careful not to drive the nails all the way through, so the inside of the shelf still looks neat. And of course, you should be patient until the glue has fully set and stabilized everything. 🙂

This is the best advice for a clean finish. Screws provide more stability compared to nails because they are less likely to slip out of the material.

Important: Countersunk screws ensure that the screws sit flush without any sharp edges protruding. This also helps prevent damage to the walls or during transport.

It is certainly questionable why IKEA doesn’t use a sturdier back panel from the start.

This criticism is valid; however, most shelving units intentionally have thin back panels to reduce weight and cost. Your idea of reinforcing with MDF is basically correct, but you should consider the added weight and potential material stresses.

One more tip for stabilizing: attaching the shelf to the wall provides additional support and relieves stress on the back panel.
