Difficult to assemble, low quality, but looks nice
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
It looks nice when finished, but it's a major pain to put together. I've assembled a lot of DIY furniture over the years, but this was one of the more frustrating ones, mainly because of the unnecessarily difficult way the finishing slats need to be attached. Also the frame was very unstable during assembly. This bookcase is also not exactly sturdy even when finished. It's a low-quality product in all respects, really, except the nice way it looks. Value for money? meh. Color is nice.

Excellent Customer Service. Follow instructions.
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I LOVE the color of this bookcase. The bookcases at the big chain store generally cost around $100, so this is about what I was expecting. It's a nicer quality with thicker shelves than the big chain store bookshelves and I really wanted the cherry color, which, on this bookcase, is gorgeous. It was a bit difficult to assemble only because I asked for help from a male friend who insisted that we skip through the directions. We ended up getting a screw caught between two beams because he didn't want to sort out the screws like I ALWAYS do before assembling any furniture. Note: just breathe, relax and take your time and follow the directions, and if you ask for help from someone, give them a sedative, like a big dose of kava or something because it's going to take several hours. Once it's finished, though, it's really lovely. I filled it with books and so far, it's been fine. It is particle board with a finish, so if you scratch it, it's going to show. But, it comes with a brown color-coordinated marker so you can cover up minor scratches or flaws in the finish. I was a little surprised that the top of the bookcase is unfinished, but maybe a lot of bookcases are not nowadays. I wouldn't put it in a location where the top of it shows - like next to a staircase. The backboard is cardboard folded in half with the same cherry finish, which for me really wasn't an issue because I always fill my bookcases completely with books so the back doesn't really show. There are weight restrictions for each shelf, so make sure you pay attention to those - some shelves hold more weight than others. I plan to assemble the second one by myself now that I understand what's involved. I have to give five stars because customer service was so amazing. I didn't open the second bookcase for a long time, but despite the time that had passed, they still replaced a damaged beam very quickly, and even reshipped the beam a second time because I had given the wrong address. That was really amazing! Never had such a good experience with customer service before.

Great socks!
These are great low cut socks with padding in appropriate places. The shape keeps them from sliding down in my tennis shoes. I just wish more than three pair came in the pack.
