ᐅ My Kallax wobbles on carpet, even though it is fully loaded.

Hello everyone,
I have a Kallax shelving unit standing on my carpeted floor. It is fully loaded—every compartment is filled with books, folders, and some decorative items. Still, the shelf noticeably wobbles as soon as I touch it or place something inside. This is unexpected because I thought the heavy load would stabilize the unit and prevent any wobbling.
I’m wondering what might be causing the wobbling. Could it be the carpet itself, an uneven surface underneath, the construction of the shelving unit, or possibly the way I have arranged the items?
Maybe there is a simple solution to make the shelf more stable without dismantling it or doing major modifications.
Does anyone have experience or tips on how to stabilize a standing Kallax shelf on a carpeted floor?
Thanks in advance!

If your carpet is very thick or fluffy, the shelf may slightly warp over time due to some feet sinking individually.Thank you for this tip. My carpet is actually quite thick and also has a foam underlay beneath it – I suspect that makes the issue worse.
I have already tried KAULIS’s suggestion with pads, but only used thin felt pads, which don’t seem to be enough.

Maybe it would help to place the heavier items at the bottom.The idea of weight distribution makes sense too – at the moment, my shelf is more randomly arranged. I will rearrange it and see if that has a positive effect.
Does anyone else have experience with very thick carpets or foam underlays combined with Kallax?
From my experience, wobbling can only be corrected to a limited extent by rearranging the contents if the base surface is uneven.
The condition of the floor is the key factor for Kallax – the frame itself is very stable, but there is little adjustment possible at the feet.
I strongly recommend a combination of the following measures:
- Use of firm, thin pads under each foot (e.g., metal or plastic plates)
- Checking and compensating for even slight inclinations with wooden wedges
- If possible, securing the shelf to the wall with screws (more resource-efficient than new furniture supports)
This will significantly improve the stability in the long term.

Has anyone else had experience with very thick carpets or foam underlays combined with Kallax?Yes, very thick carpets with additional foam pads underneath definitely cause issues with heavy furniture. Individual feet sinking often leads to tilting and wobbling because the shelf is resting on uneven pressure points.
Technically, the problem is that Kallax does not have adjustable feet. This means that on soft surfaces, not all feet can rest firmly and evenly.
My advice: use high-quality floor glides made from a harder material and adjust them to the appropriate height underneath. If that’s not enough, placing a thin, rigid board (e.g., plywood or MDF) under the shelf and carpet can help distribute weight and surface area.
Mounting the unit to the wall also increases stability and prevents tipping.
Finally, if possible, check whether the carpet is noticeably soft or less firm at that spot and if it visibly compresses under the weight.

Wall mounting also increases stability against tipping.True, and besides that, the shelf resists its natural tendency to wobble much better. 😄
I think with a few practical tricks and maybe moving the Kallax to a different spot (away from the fluff disaster zone), you can solve all of this.
For fun, here’s my secret tip: Placing a small rug under the Kallax only helps so much, especially if the rug is too thick and soft – a thin board as a base works better and makes the shelf much more stable.
Thumbs up for the Kallax, but rug + Kallax = it always takes a bit of care and effort!

I have already tried KAULIS’s suggestion with the documents, but only with thin felt pads, which don’t seem to be sufficient.Felt pads are primarily designed to protect floors and furniture bottoms, and are not necessarily suitable for stabilizing on very uneven or soft surfaces.
I therefore recommend materials with better grip and higher durability, such as hard rubber or plastic glides that do not compress.
Equally important is checking the feet for any deformities or damage. Older Kallax models may have defects that cause wobbling.
Additionally, if possible, installing a diagonal brace at the back of the shelving unit can improve both stability and structural integrity.
