Hello everyone,
I recently bought an IKEA Kallax shelving unit and want to use it flexibly in the room, so I mounted it on castors. However, I now have the problem that the unit often feels unstable when pushed—especially when it is loaded or moved a bit faster. It wobbles or jerks, and I’m worried it could get damaged over time or even tip over.
I’m therefore interested in how to best stabilize the Kallax on castors so that it remains secure and doesn’t sway annoyingly while being pushed. Are there any proven tricks or recommended wheel types? Maybe tips for fixing it in place or adding extra stabilizing elements? I’ve considered small brackets or additional braces, but I’m unsure what would really be effective without altering the design too much.
Looking forward to your advice!

Caster plate securely attached to the cabinet (with screws, not just inserted)Exactly, this is often underestimated! When the whole thing starts to wobble over time, it’s usually because the casters aren’t firmly screwed in. Screws can also gradually loosen, especially if the shelf is moved frequently.
Another tip from me: if you don’t want to buy new casters, you can try sticking small rubber bumpers under the casters. They act as shock absorbers and make pushing smoother. When you then push the shelf, the force is better distributed, reducing wobbling.
And don’t worry about small modifications—as long as they’re stable, they are usually hardly noticeable. 🙂
I can understand that the Kallax on casters sometimes wobbles annoyingly – I experienced that myself. What helped me was actually a combination of good casters and a small adjustment to how they were attached. It was important to me that the shelf doesn’t jerk when pushed because I was worried that over time the wood might get damaged or the joints might loosen.
I had the same concern, so I would also recommend paying attention to the type of floor. Carpet or uneven tiles increase the wobbling significantly. Choosing good casters and lockable wheels helps, but it’s simply more difficult on carpet.
If you want to move the shelf often without constantly holding the wheels, in my experience the best solution is to combine permanent fixing (wall brackets or floor clamps) with flexible casters on top. This way, mobility is preserved but stability is ensured.
If this could be a solution for you, I’m happy to share more details on how I implemented it.

Hello JILLDAN,
I would like to add some basic points that can help keep your Kallax shelf on casters stable:
1. Caster quality: Cheap plastic casters often lack durability and can cause instability. Rubber or polyurethane casters with good ball bearings provide smoother movement and protect the floor.
2. Attachment: The casters must be securely screwed on, ideally using additional washers to prevent the screws from loosening.
3. Load distribution: Consider how you distribute the load on the Kallax. One-sided loading can increase the risk of tipping or wobbling.
4. Additional brackets: Installing metal brackets inside the corners definitely improves the frame’s rigidity. However, they must be attached carefully.
5. Alternative: If stability and casters are very important to you, there are special furniture casters with built-in suspension, which ensure stability even on uneven floors.
In general, a good compromise of quality casters, secure attachment, and slight mechanical reinforcement is the best approach. If you want, I can recommend specific types of casters that I have used several times.
