And they make it very clear what things are made of in the meterials section. Most retailers don't

Same model of Kallax shelf now is made from paper. Price is even higher. I have older wooden models. The new one has even slightly different size. I was taken by surprise.

Kallax was never made from "wood". The new one is quite study particle board filled with honey comb paper, the old one was very thin MDF with carton spacers. I have both an old expedit and a new kallax and there is no noticable difference. The main downfall of both is the coating with is thin and easy to destroy.

Obviously I bought something else than IKEA product some 15 years ago. It was 5x5 huge wooden shelf. Had problems to lift parts of it and sold later for more than I paid. Deal of lifetime!

> Expedit and Kallax have different size

Yes, but Kallax is IKEA's official replacement for Expedit.

The predecessor of Kallax was also made from paper (and it was called Expedit). I know because I hade to saw it apart to be able to lug it to the recycling.
