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.

I like the ankle length, they don’t slip.
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I love these socks, they are thick enough to not be scratchy, thin enough to be cool and breathable.

Fit great
Size: Large, Color: (100) White / White / Halo Gray
Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.
