ᐅ IKEA Besta: How to Fix Wobbly Drawers?

Hello everyone,

Some time ago, I assembled an IKEA Besta shelving unit with several drawers, and although everything was installed correctly, a few drawers wobble noticeably when opening and closing. This mainly concerns the side drawer slides, which seem either not stable enough or have some play.

Can someone explain what usually causes this wobbling? Is it a known issue with Besta, possibly related to the slides or the material quality? What steps would you recommend to improve stability without having to fully dismantle or alter the construction?

Any detailed advice, including regarding specific screws or components, would be greatly appreciated, as I would like to fix this issue properly. Thanks in advance!

This is a common issue with IKEA Besta, especially if the drawer slides are not installed perfectly straight or if some parts are slightly bent.

A few tips for checking and fixing this:
- Make sure the slides are mounted exactly straight and firmly on both sides. Even small misalignments can cause wobbling.
- Check if the metal runners are properly snapped into place; sometimes the plastic clips are not fully engaged.
- Remove the drawer and test the slides separately to see if they catch or have play.
- Gently tighten all screws; IKEA sometimes uses small screws that can loosen over time.

Sometimes it helps to remove the slides completely, lightly lubricate them with silicone spray, and then reinstall. However, avoid excessive lubrication as it can attract dust.

If the slides are damaged or deformed, replacing them can help. Spare parts are usually available from IKEA or online as replacement parts.

I’m happy to provide more specific advice for your particular drawer type if you have more details.

Yes, instability in the drawers of the IKEA Besta series is a well-known issue within the community. The primary cause is often related to the drawer slides and guides, which are made from lightweight steel sheet metal and sometimes allow for slight tolerance in how they are mounted.

Common standardized solutions include:
- Checking the precise alignment of the slides using a spirit level or angle tool.
- Strengthening the fixing points by carefully tightening the screws without damaging the material.
- Adding washers to the mounting screws to reduce play.
- If necessary, replacing the slides with higher-quality compatible models to ensure a more stable glide path.

Since Besta is modular furniture, it is important to avoid voiding the warranty by unauthorized modifications. However, gentle readjustments are usually unproblematic.

It is also crucial to ensure that the drawers themselves are not warped, as this can increase the looseness.

Wobbly drawers in the Besta system can often be fixed by tightening the screws and properly adjusting the slides. If that doesn’t help, check the plastic inserts and replace them if they are damaged.

Using washers on fastening screws to reduce play.

I wonder if this is really the optimal solution. Washers can temporarily reduce play, but might they also cause increased wear on the guide rails or other components?

It would also be interesting to know if IKEA has an official statement regarding this wobbling issue or if the design approach for Besta here is fundamentally in need of improvement.

In my opinion, the choice of material for the running rails—thin sheet steel—could quickly lead to fatigue under higher stress, which would increase the wobbling. This issue should perhaps be addressed at a different level, namely in the design phase, rather than only treating the symptoms.

Thanks for this tip, that sounds very helpful. So far, I’ve avoided removing everything because I was worried it might cause even more problems afterwards.

That makes sense to me – after all, the furniture in our home is used frequently and is sometimes loaded with considerable weight.

My question to the experts here: in your opinion, is it worth investing in potentially different running rails that can be retrofitted? Or should the original rails hold up permanently if installed correctly?

I want to avoid changing the whole system if a professional adjustment is sufficient.
