Cubby shelf unit / small bookcase (NE Ithaca)

Hello ReUsers,

We are looking for a "cubby" shelf unit or small bookcase for our kiddo's room. She needs a place to sort her toys and other items.

--Something like this: https://www.ikea.com/us/en/p/kallax-shelf-unit-white-80275887/
--Or this: https://www.wayfair.com/furniture/pdp/closetmaid-decorative-storage-30-h-x-...

I'd also welcome any ideas for other places to look for this item? Would ideal like to get this second-hand.

Thank you!
Lanie
