Kallax is ridiculously expensive and you pay for the hip IKEA brand (yes, IKEA is fancy in many regards). Especially for a bookshelf, you can build it yourself way cheaper. Go to IKEA to get inspiration and to check how the fiberboards are put together to construct the furniture. Then you can go to a hardware store that sells fiberboards, cut to your size specifications. In many places you can ask them to cover specific edges too. You buy the screws, the door hinges etc. A bookshelf is essentially four boards plus a few shelves themselves. Ridiculously easy to construct yourself out of boards and won't cost as much as a Kallax. Also IKEA is often not even using fiberboard but hollow cardboard like this https://www.ikea.com/de/de/images/products/lack-couchtisch-weiss__1083778_pe859098_s5.jpg?f=xl https://www.ikea.com/de/de/images/products/lack-couchtisch-w... Once you get some routine, it's no huge deal to build more stuff yourself. With my dad, we built all our kitchen furniture with MDF boards, 3D modeled in the SketchUp software by us for millimeter precision. And again, you can ask hardware shops to do a lot of stuff for you, like make curved cuts etc. Couches are of course another deal totally. But shelves/cupboards/wardrobes are totally possible to build yourself.
