Hello everyone,
Some time ago, I bought an IKEA Kallax shelving unit with caster wheels to make it easier to move around the room. Unfortunately, I noticed that the unit tends to tip forward, even when only lightly loaded—especially when using the upper shelves. The casters can be locked, but that doesn’t seem to prevent the tipping very well.
I’m interested in proven solutions or modifications you know of to effectively secure the Kallax on wheels against tipping forward. Are there special fasteners, different types of casters, or additional stabilization options that can make the unit safer?
If it’s relevant: The unit stands on carpet, is filled with books and decorations, and the casters have a standard diameter of about 5cm (2 inches).
Thanks in advance for your tips!

A brief addition:
In my solution, I also attached two metal rods horizontally to the back, which can be secured to the wall with magnetic hooks. This keeps the shelf movable but prevents it from tipping over or sliding away.
Of course, this is not visually invisible, but with tall Kallax shelves, any passive safety measure can help.
The important thing is the combination of lockable casters + tipping protection + low center of gravity to create a safe piece of furniture.

A critical question: Have you ever checked the load-bearing capacity of the Kallax casters?
It’s easy to overestimate their strength – this can lead to tipping if the wheels deform or jam.
It would be helpful if someone could provide specific manufacturer data or maximum load limits for the casters used by fasuba.
Therefore, combining them with wall fixings is more of a safety measure than a recommendation to rely solely on the caster system.

Thank you for the many responses; they have really helped me a lot!
I find your suggestions about combining different approaches particularly important: lowering the center of gravity, the quality of the casters, and securing the wall attachment with a locking mechanism.
To answer a few questions: The shelf needs to remain easily movable, so a permanent screw connection to the wall is not desired. I’m open to semi-flexible solutions like wall rails or magnetic holders.
I will also try the recommendation to switch to better casters and, if necessary, add base plates or larger support surfaces.
The only remaining question is how to best secure weights at the bottom of the shelf without compromising its mobility too much. Do you have any experience with this?

Regarding adding weight at the bottom: I simply placed heavy books or binders in the lower compartments. If that’s too loose, you could also use lead plates or small sandbags inside sturdy plastic containers.
I would make sure the weights are well packed in boxes or something similar, so they can be quickly removed when moving the unit. Ideally, the containers also help dampen any unwanted slipping of the weights. This also keeps rolling and sliding smooth.
The important thing is that the weight is concentrated at the bottom, not spread out sideways.

Regarding weight distribution versus mobility:
The best compromise is to fill the lower compartments with heavy but easily portable containers. Plastic boxes with handles make it simple to remove and move these weights when needed. Using rubber mats beneath the containers can also improve stability and reduce slipping.
Additionally, I recommend regularly checking the casters for firmness and functionality, as wear increases the risk of tipping.
With the trend toward smaller wheels on Kallax units, instability often results here. Larger wheels (at least 50 mm (2 inches) in diameter), ideally with brakes, are better.
