ᐅ KALLAX as a Platform: Are Metal or Plastic Feet Better?

Hello everyone, I am currently considering using my IKEA KALLAX shelf as a platform for a small stage or as a riser in the living room. My question is: Are metal or plastic feet better suited to make the KALLAX shelf safe and stable over the long term as a platform?

I am mainly concerned with aspects such as load-bearing capacity, durability, load distribution, as well as the visual impact and any potential noise or material expansion.

Does anyone have everyday experience or knowledge of the differences? If anyone also knows load specifications, I would appreciate that! Thanks in advance for your input.

Metal legs are more stable and durable than plastic. If you want to use the KALLAX shelf as a platform, metal legs provide better support and less deformation under load.

True, metal does have its own appeal – it feels solid and usually looks more elegant. But I think plastic feet can also have an advantage: they are lighter and gentler on the floor, especially if it often comes into contact with hard surfaces.

And hey, if the platform isn’t moved around frequently, plastic might be sufficient, especially if it is of good quality. Sometimes less is more, especially with smaller projects. 🙂

Regarding the suitability of metal versus plastic feet for a KALLAX shelf used as a platform, load distribution is the key factor. Metal feet offer better load-bearing capacity and resistance to deformation, even under point loads. Plastic feet generally have lower mechanical strength and can undergo permanent deformation under continuous load, especially if made from soft plastics.

Abrasion and scratch resistance are also important: metal feet are clearly advantageous here, preventing damage to the floor and offering better heat resistance.

However, metal feet can cause rattling noises if the platform is not resting evenly, or if slight expansions occur due to temperature changes.

For a durable, load-bearing platform, I would therefore recommend metal feet, provided that appearance and noise development are not the primary concerns.

Thanks for the detailed assessment!

What about installation? Do metal feet or the corresponding KALLAX foot sets have special requirements, or do you simply drill as with plastic feet? Or is the stability in my case still limited by the type of attachment?

That’s a good point, which is actually relevant for me – I have a laminate floor that also has uneven spots. Could metal feet potentially damage the floor more in this case?

Which specific foot models or brands would you recommend? And do you have any tips on how to install metal feet in a way that still protects the floor somewhat? Thank you!
