Anyone have recs for good quality but affordable bookshelves? We have a shit ton of books, mostly stored in boxes and on crappy old bookshelves (one of which is going to tip over and DESTROY US ALLLLLL!!!!).

So, I’d like some actual grownup bookshelves that will stay firmly planted on the ground, contain an amount of books that’d give Marie Kondo a serious stress headache, look good, last for a long time, and not cost a bajillion bucks.

Any ideas?
