>>21820595you can get those "uline" brand wire shelves, the ones for warehouses
they're incredibly cheap and sturdy (500lb+ per shelf), and versatile (you build/configure htem yourself, each shelf at whatever height you want, any number of levels per shelf)
just pay attention to the max weight per shelf, whatever you end up buying
a lot of them suck ass
you'll get something advertised as a bookshelf but it would collapse after 1/3rd filled with books
