First of all, bonus! I assumed I was only getting 1 bookcase, even though the picture shows 2. I read a review where the customer stated they only received 1 confirming what I thought. However, I received 2.  This made things a little better as I think the item is priced a little high for the quality for just 1 bookcase. The shelves are particle board and the posts are plastic. The bookcase is a bit wobbly. A wall screw is included if you want to use it. We chose not to, not wanting to put a hole in the wall. But you could use it and it would probably make it more steady. My husband slid a piece of wood under the front post on the bottom shelf and that seems to work. All in all, it's not bad. The bookcase looks good in my 3 season porch and I put the other one near the kitchen pantry to hold my cookbooks.
