Easy enough to assemble (very Ikea-like). Didn't quite fit the space we wanted it for, so we modified (with a saw!!) to make it look more like a built in. Did not use the bottom or top accent rails. Stacked nicely.
Dislikes: boards not painted on the undersides. This won't impact everyone but it does for us as it sits up high along a staircase in a backdoor mudroom so you can see the unpainted parts.
