Question: What is the distance from the top of one shelf to the bottom of the next shelf up?  Would it be tall enough to hold a 12" tall book?
Document: Ok since it's going in a corner and that side would be against a wall. You assemble the rear supports and shelves on one side of the frame first. The first back support split when trying to insert the pegs. Guess the holes were a little off. Ok, so I put that one on the bottom so it wouldn't be noticeable. Once one side is assembled then you have to fight about 12 dow pegs into the holes of the other side of the frame at the same time.
I needed a shelf system which would not be over 52 inches tall and it had to be narrow. I purchased this item and the accompanyingWinsome Wood Leo Storage Baskets, Set of 2, Espresso. The shelf was perfect for our needs where it would be set back in a little niche in our house. I used the baskets for the bottom 2 shelves and put antique books on the upper shelves.
These were easy to put together,look great and hold a crap ton of books. If you are looking for a cheap but good quality book shelf this is it.
This is the perfect book shelf Ive been looking for. It doesn't take up to much room and holds plenty of my wife's books in the bedroom.To top it off, it's actually well built,looks great and easy to assemble.Thx again Amazon
The espresso color is a rich dark brown and compliments the other dark wood furniture in the room (please see picture that I uploaded, showing shelf next to my antique piano). My unit arrived without any damage or scratches and was packaged nicely. The shelf is a product of Thailand and is distributed via British Columbia, Canada. The shelves are generously deep, allowing for tall and oversized books to be inserted and stored; many of my cookbooks are oversized and this shelf works perfectly for storing them.
You only need to hammer it in until there's a couple threads sticking out the other side. You'll want to balance the ladder piece on something like a cardboard box while you do this, so you don't hammer them into your floor.Then, you can line up the screws and screw them in like normal. Not bad for an extra half hour of work. It's a bit tougher for the screws that hold on the top shelf, but the same method works.Oh, the shelfs?
Also, the shelf pieces have a definite top and bottom and that helps.The materials (noted as wood/composite wood) do not have a plastic/chemical odor or appearance. The pieces have a slight wood+stain odor that is not bad at all. I really appreciated that the wood grain is all going the same direction on each of the shelf pieces. Also included is a form to fax in for any missing or damaged parts to be replaced by the manufacturer.
Perfect tall, narrow bookshelf. The color matches almost exactly to some other espresso furniture I have from other manufacturers. Seems very sturdy and was one of the easiest things I've ever put together. I would buy this again in a heartbeat.
We really like our new shelf! It went together in about a half hour and holds so much. Because it is narrow, I suggest you use the bottom shelves for your heavier items to keep it from becoming top heavy. If you follow the directions you won't have any trouble putting this together, other than perhaps having to use some elbow grease to make sure all your screws and such line up with the correct holes. This is to be expected with a knock-down piece of furniture.
Chose a rating of 5 since this bookshelf is the perfect size for my small space. Love it.I would recommend this book shelf to anyone who had a small space and needs a shelving unit.
Answer: Exactly 12 "
