One thing that is nice about IKEA is since everything is pretty standardized you can create mashups that were never intended. For example, they sell a bathroom vanity on little 3 in legs - but the legs are the same as the bookcase legs elsewhere in the store - which are also available in 6 inch. So if you want a higher vanity you can easily do it.

But other stores have caught on to flatpack shipping - you can get solid wood dressers for example from Target shipped as a flatpack and easiesh to assemble (have a power screwdriver or drill torqued down low).

The problem is some of the things you have no idea of the durability until you’ve used it.

For example this is good: https://www.ikea.com/us/en/p/hejne-4-section-shelving-unit-s... especially for the price (accommodates rack units!) but this is an absolute pain in the arse https://www.ikea.com/us/en/cat/ivar-system-11703/ to get working correctly (I threw it away and burned the rest after the third time shelves bounced and collapsed).

I ended up replacing most of it with wire shelving from Uline.
