ᐅ Using a Kallax as a Workbench – Load-Bearing Capacity for Heavy Tools?

Hello everyone, I’m currently considering using an Ikea Kallax shelf as a workbench. More specifically, I’m wondering how sturdy a Kallax really is when placing relatively heavy equipment on it, such as a sewing machine, possibly a small lathe, or even a larger printer.
Does anyone have experience with how stable the shelf is as a tabletop? I’m particularly interested in whether the structure can reliably support the weight without warping or becoming unstable – even with somewhat dynamic use, like when working more forcefully.
Does anyone have tips for reinforcement or know of potential weak points? I want to avoid unnecessary damage while creating a cozy, practical crafting setup. Thanks in advance for your feedback!

Additional note: If you plan to use heavy equipment more frequently in the medium term, you should not only consider the maximum load capacity of individual panels but also the overall stability of the substructure.
The Ikea Kallax shelf is not designed for horizontal loads with high bending moments. Static loads are acceptable, but dynamic loads can cause issues at the connection points.
Recommendation: A bracing that stabilizes the base structure at the corners, for example by diagonal braces or a U-shaped metal frame under the shelves, can significantly improve the overall stability.

A stiffening element that stabilizes the base structure around the corner can significantly improve overall stability.That's exactly what I noticed as well since I added diagonal brackets underneath the front of the board — no more wobbling! It’s a bit of extra work, but definitely worth it if you use it a lot!

The load-bearing capacity is really good now; the sewing machine is completely stable, and the lathe can be operated much more smoothly. It’s a bit more expensive and labor-intensive than I initially thought, but definitely worth the effort.
Thanks to everyone who shared their knowledge here! For anyone planning to use their Kallax as a workbench, I highly recommend investing in reinforcements to increase its load capacity.

That confirms my assessment: If you understand the material’s limitations and work deliberately with appropriate reinforcements, a functional workbench can be created from what seems like basic material. That is exactly sustainable and efficient use of resources.
