ᐅ Ikea BESTA – How do I properly install the back panel?

Hello everyone,

I am currently assembling my new Ikea Besta cabinet and am having trouble with the back panel. The instructions show how to generally insert the back panel, but for my model, it is larger than the actual opening for the back panel, and I am unsure how to properly secure it to keep the cabinet stable and prevent any wobbling.

Should the back panel be nailed or glued somewhere before assembly? Or is it simply inserted between the cabinet carcass and the back? Are there any special brackets or fasteners I might have missed?

I would really appreciate a detailed explanation or tips on how to correctly and permanently secure the back panel, especially for the Ikea Besta series. Thanks in advance!

The back panel is usually just slotted in and then fixed to the cabinet with small nails. Check if the set includes these small nails—in that case, you can nail them around the edges of the back panel. You don’t need to glue or hold anything in place beforehand.

Hello reopin,

to answer your question in more detail: The back panels in Ikea BESTA units are usually made of thin particleboard or MDF, which are not glued but attached with small nails.

- You should insert the back panel so that it fits exactly into the grooves on the back of the cabinet. These grooves serve as a guide.
- Then carefully tap in the thin supplied nails all around. These should be evenly spaced, usually about 10-15 small nails per back panel.
- It is recommended to use a hammer and place some paper under the nail to prevent the back panel from splitting.

Many recommend not attaching the back panel before assembling the side panels, as this makes the cabinet more stable.

If you have a back panel that is larger than the back of the cabinet, you may need to insert it before all sides are fully screwed together.

If the back panel consists of multiple parts or is unusually large, also check whether there are additional brackets or screws included in the package.

Thanks a lot for the clear explanation, gregto! That really helps me.

One more question: After inserting and nailing the back panel, should the cabinet no longer have any tension, or how does warping come into play? Sometimes I get the impression that with thin particleboard back panels, the frame remains a bit shaky because the back panel isn’t properly secured.

Do I need to be especially careful to make sure the back panel lies completely flat? Or is it okay to press or slightly bend it by nailing in order to stabilize the frame? I definitely want to avoid damaging the back panel. Thanks!

This is an interesting question.

Basically, the back panel is an important component for lateral stiffness, but it must not be forcibly bent or stretched.

I often question whether the standard method used by Ikea – simply nailing thin back panels – is truly sufficient to provide long-term stability.

Often, the back panel is just attached as a rigid element to the carcass, instead of creating a flexible connection that can accommodate small movements of the wood.

My suggestion: If the back panel seems too thin or unstable, pay close attention to ensuring it lies completely flat. You can fit it into the grooves without bending it and then carefully nail it in place. It is important that no tension remains in the material, as this can cause cracks due to temperature fluctuations.

If possible, you can also add additional brackets inside the carcass if nailing alone is not enough. This will increase stability without forcing the back panel to warp.

This would be a constructive compromise that should work better in the long run.

Hello reopin! I’m glad you’re taking the time to assemble the BESTA properly! I recently built the cabinet myself and can assure you that the back panel really provides excellent stability when installed correctly.

My tip:
- Simply slide the back panel into the groove, no force needed.
- Then use a small hammer to evenly drive in the nails – I always placed a small piece of wood between the hammer and the nail to prevent splintering.
- Once it’s in place, the frame feels much more stable – no more wobbling!

Good luck – you’ve got this! 🙂
