ᐅ The edges of my KALLAX units start chipping right after assembly – is that normal?

Hello everyone,

I recently assembled a KALLAX shelving unit from Ikea and am quite disappointed: shortly after putting it together, the edges started chipping in several places. I handled the assembly very carefully, without applying force or excessive pressure. Now I’m wondering if this is normal for KALLAX units or if I might have received a defective batch or poor workmanship.

I am familiar with the material and know it is melamine-coated chipboard, but I didn’t expect the edges to be this delicate, especially since it’s designed for everyday use.

Have any of you experienced similar issues? Are there any tips to prevent such damage during assembly? I look forward to your experiences and advice because I find the shelving unit really practical—only the fragility concerns me.

Thanks in advance!

That really sounds frustrating, especially since you took care to put everything together carefully. I haven’t had major issues with KALLAX myself, but I understand how annoying that can be.

Sometimes the edges can be a bit fragile, especially if the outer packaging was already slightly damaged or if the product had minor signs of transport. It’s also possible that some batches vary in quality.

Did you use any particular step or tool during assembly that might have put extra strain on the edges? Or did you notice the chips at the corners right when unpacking?

Hang in there, I’m sure there are solutions, and if you want, we can take a closer look here.

Hello,

I can provide some context and share a few tips based on experience with KALLAX and similar furniture:

1. Material characteristics: Although the melamine-coated particleboard is durable against moisture and scratches, the edges are often only thinly covered with a film that can easily fray or chip.

2. Follow assembly instructions: Pay close attention to the correct tightening of screws and avoid bending the parts with excessive force. Especially when the holes for dowels are slightly misaligned, too much pressure can damage the panel edges.

3. Choice of tools: Using a screwdriver with torque control or a cordless drill set to low torque can help prevent applying excessive pressure.

4. Edge protection: Before assembly, you can carefully deburr the edges with fine sandpaper if there are already small irregularities.

5. Inspect parts: Check the components for cracks or damaged corners when unpacking. For more significant damage, it’s best to use the warranty.

Summary: Chipping can occur with KALLAX, but it is often caused by improper pressure or pre-existing minor weaknesses.

I hope these tips help you. If you like, I can also explain individual assembly steps in detail.

This is exactly where I want to start and explore the topic from a technical perspective:

The KALLAX shelf is made from a calibrated wood particle core covered with a melamine resin coating. This combination offers a good balance between cost and workability. However, this surface is relatively brittle on the edges, as the protective film is only heat-shrunk there and does not form a solid edge.

In detail: Stress in the film caused by moisture absorption and temperature changes can make the transitions less stable. During assembly, two critical factors come together:

1. Mechanical stress on the edges, especially when boards are joined slightly crooked.

2. Tensile stress from screws or dowels that are not positioned exactly and displace the material.

Therefore, I explicitly recommend:

- Use a cordless drill with fine torque control.
- Insert the screws slowly and evenly, avoiding angled screwing.
- Check that you assemble the shelf on a level and stable surface.
- You can repair cuts or cracks with very fine furniture filler to prevent further tearing.

In conclusion: It is not normal for the edges to splinter immediately, but a combination of material properties, assembly errors, or small manufacturing tolerances can unfortunately cause it.

I would be interested to know whether you followed the instructions exactly and if you used a cordless drill or only manual tools.
