ᐅ KALLAX Shelf Wobbles – What Can Be Done?

Hello everyone, I recently assembled a KALLAX shelf from IKEA, but unfortunately it wobbles quite a bit even though I tightened all the screws firmly. It is placed on a level floor and is not overloaded. My question is: What can I do to improve the stability of my KALLAX shelf? Are there any known weak points or specific tips for reinforcement? Many thanks in advance for your advice!

Hello Maotto, with KALLAX shelves, it is indeed the case that the plug-in joints on the sides sometimes do not provide enough stability. First, check whether all connections are properly and securely fitted together, especially the connectors on the back panel. One way to improve stability is to use additional corner brackets or small wall anchors if the wall allows it. Additionally, a solid reinforcement of the back panel, which often consists of only thin boards, helps as well.

Check all screws again and tighten them completely. Make sure the shelf is standing on a fully level surface. If necessary, place small shims or washers under the feet.

Thanks for the tips so far! I have already checked all the screws, and the shelf is placed on a tiled floor that is completely level. The back panel is the standard fiberboard fixed with small nails. Is it advisable to replace the back panel or reinforce it to reduce wobbling? Are there identical KALLAX models with sturdier back panels or community modifications?

That’s exactly what I would recommend! I once fixed my KALLAX to the wall using a few small metal brackets – it holds very well and doesn’t clash with the appearance. Also, a small tip from me: lightly secure the shelves on the sides with wood glue; this also helps prevent that annoying wobbling.

These particleboard panels used as back panels on IKEA shelves are more decorative than structural. If you want them to be truly stable, you need to be creative and either add proper plywood sheets behind them or reinforce them with metal. I find it quite frustrating that IKEA skims on stability here – additional costs for more robust back panels should be mandatory.
