This has become my new favorite bookcase. I needed a new one to replace one that was falling apart when I found this. 2 of these almost matched the dimensions of my old one and the shelves were sturdier. I also live in a small space so these bookshelves are really handy to have around. I loved the two I ordered so much, I ordered a third for a nearby space, and thinking about a 4th for extra bathroom organization.
I felt the assembly instructions were pretty straightforward. I never had to guess or deduce which way a part was supposed to be facing. From start to finish I'd guess was about an hour to an hour and a half.
I highly recommend these units and think if you were to pick one up you'd be happy with your purchase.
