ᐅ Are there any common issues when assembling IKEA Besta units, and how can they be resolved?

Hello everyone,

I am currently planning to assemble an IKEA Besta cabinet and have already heard from some friends that it seems to have certain well-known issues during assembly. Although I am reading the instructions thoroughly, I still cannot anticipate all potential pitfalls in advance, so I wanted to ask here in the forum: Are there specific difficulties or common mistakes that frequently occur when putting together the Besta components?

I am particularly interested in whether there are mechanical problems such as fitting inaccuracies, difficulties aligning the doors, or challenges with the mounting hardware. Tips on preparation and tool selection would also be helpful.

I look forward to hearing about your experiences and proven solutions so that I can complete the assembly as efficiently and frustration-free as possible. Thanks in advance!

Hello @kloeduard,

I completely understand your question – the Besta cabinet is very popular, but there are a few points to keep in mind during assembly to avoid problems.

A common issue is the fit of the back panels. Often, the grooves are not perfectly milled, so the back panel may sometimes sit crooked or get stuck when sliding it in. I recommend lightly sanding the back panel before screwing it in, or carefully removing some material from the groove with a sanding block. This makes sliding it in much easier.

Also, with some models, the pre-drilled holes for fittings don’t line up perfectly. Especially with the hinges, you need to align the front panels very precisely during assembly. It often takes several fine adjustments until the doors close properly and fit flush. A screwdriver with adjustable torque is ideal for making these small corrections.

Another tip: use high-quality screwdrivers with the right bits, ideally with a magnetic tip to prevent screws from constantly falling out – this is especially helpful with the small barrel nuts used in the Besta series.

If you plan to attach the cabinet to the wall, make sure to check the condition of the wall surface and use appropriate anchors. For drywall (plasterboard), be sure to use hollow wall anchors or special drywall anchors.

If you have more detailed questions about any stage of the build, I’m happy to help!

That is correct and has also been pointed out in IKEA’s assembly instructions. This is not a design flaw but manufacturing tolerances common in solid wood or wood-based products.

Additionally, I recommend considering the following points:
- Check all parts for completeness and damage before starting
- Use a flat and sufficiently large workspace
- Sort all screws and fittings before assembly

For door adjustment, the screws integrated into the hinges help. They allow precise fine-tuning both in depth and height.

Finally, a recommendation regarding the number of screws: not all screws are always strictly necessary; in some cases, proper positioning can achieve a stable build with fewer fasteners, especially when space is limited or the instructions suggest unrealistic assembly sequences.

These tips should help to eliminate potential sources of error and make the assembly process more efficient.

I often had problems with the small dowels not holding properly when assembling the Besta. I recommend securing them with a bit of wood glue. This makes everything more stable and prevents wobbling later on.

That is a good tip. Adding wood glue to wooden dowels significantly increases stability and reduces wobbling after assembly.

Additionally, for some Besta components, you can use tacky adhesive putty or double-sided tape if you need to temporarily adjust something before final fixing. Especially when combining several modules, it’s worth allowing some flexibility during assembly and working step by step.

It is also very important to avoid applying too much force when wooden dowels or screws get stuck. It’s better to check if the part is properly positioned to prevent damage to the wood surface or misalignment of the fittings.
