Hello everyone,
I recently noticed that some of the boards on my IKEA KALLAX shelving unit are splintering at the corners. This mostly happens on the outer, visible edges and doesn’t seem to be just a surface issue—the wood or panels actually appear to be splitting apart in some areas.
I’ve used the shelving unit normally, with no unusual loads or exposure to heat sources like lighters nearby. I’m wondering what typically causes this kind of problem with the KALLAX?
Could it be a material defect, poor surface finishing, incorrect assembly, or maybe pressure points from the dowels used?
Does anyone have experience with this or well-founded guesses about why the boards on KALLAX often splinter at the corners?

For clarification: The KALLAX shelving unit actually uses a medium-density fiberboard (MDF) with a melamine foil surface coating. A common weakness of this material is the unprotected areas at mitred or joint edges.
The chipping usually occurs because the boards are not finished with edge banding; instead, the melamine foil extends directly to the cut edge. Moisture, mechanical stress, or pressure from dowels can then cause the fibers to split.
An improvement would be to round off the edges after cutting or to apply plastic edge banding, although this would be costly in mass production and would affect the price structure.
In summary: the causes are the choice of material with an inherent weakness at the edges, a design without edge protection, and operating conditions involving mechanical stress.

Wow, so many great points have already been raised here!
I’m really glad to see such well-informed technical discussions – it’s incredibly helpful when deciding how to best maintain and repair your KALLAX.
For those who, like me, prefer not to replace the boards right away: try using these special plastic edge protectors that you can simply stick on! They work especially well for corners that experience light wear and tear regularly and help prevent splintering :-)
I can also only encourage addressing minor damages quickly before they worsen. This really saves a lot of trouble and money later on!
Good luck to everyone aiming to get their KALLAX looking great again! 🙂
