Nice Inexpensive Tall Bookcase

For the money, this is a great bookcase. The instruction manual is one of the best that I have seen. Printed on large paper and stapled with very clear assembly steps. Took me less than an hour to assemble. You will need a hammer and Phillips screwdriver. This bookcase uses particle board, which keeps cost down, but is not great when it comes time to move. The bookcase looks great. I put one in my bedroom. In summary, this is a good value if you have time for assembly - one person about an hour.

Looks great!

This bookcase is pretty sturdy for particle board. I have a lot of books that I like to display. I actually have 4 of these bookcases. Easy to assemble. There were some areas that are tricky if you are putting together by yourself. I would definitely buy again.

Great bookcase to store anything

Love this bookcase. It was so easy to put together that I did it by myself. It is well made and very sturdy. I purchased it to store my bags.
