Question: I have A LOT of heavy text books.  Will this book case hold up?  I'm planning to order 2 of them.
Document: I love it. I bought it for my bedroom. It is a perfect fit. I am enjoying  having the book case.
Just love this unit. Arrived 2 days before I thought it would and in great shape. Good instructions and was easy to put together.
I didn't have high expectations because I knew it was a piece of furniture that I was putting together. However, it is a very nice piece, solid made and I'm very happy with it. Also, it was VERY easy to put together.
I ordered 2 of these bookshelves. The boxes were in perfect condition upon arrival, but after I opened them I found that BOTH of the shelves had cracked or fully broken pieces. It was very disappointing, to say the least.
I ordered 2 bookcases. One went together just fine. The other had a missing shelf. I called and it was shipped right away, a very nice customer service lady! The shelves look very nice in my classroom!
We are very happy with our bookcases. After reading some reviews i took a chance and orderd 2 bookcases It I put i put them together in about 30 minutes. they are very attractive and perfectly sized for our needs. For the price you cant go wrong,I would recommend this product.
Went together as expected. A little challenging to line up parts - not perfect. Sufficient for everyday storage - definitely not a show piece - but attractive.
I was pleasantly surprised by this bookcase. It was very easy to assemble, and looks more like a finished piece from a furniture store than a typical assemble-it-yourself bookcase. It is also very sturdy and I am comfortable with having a 20 gallon aquarium on top. I have a corn snake, not fish, so it is not as heavy as it would be if it was filled with water.
This is an incredible value and it looks like it was very expensive. It completes my cherry reception desk and 2 drawer filing credenza like all three pieces were a set. Can't go wrong with this purchase
Wasn't sure when I ordered the product. But, other then a few labeling stickers missing it was very easy to put together, and looks great.
Answer: The particle board seems study, but I haven't been able to assemble it by myself.
