Question: What are the measurements of this bookcase?
Document: Though the bookcase looked appealing the cardboard box it came in would have been a better product. Sadly disappointing product.
This product was well constructed and fairly easy to assemble. Some of the packing materials, however, are terrible as they cling to everything (your clothes, the bookcase, floor, furniture...literally everything). I've encountered this before with projects shipped from China.
I love the bookcase, but I am giving it a lower rating because it it one of the most complicated things that I have ever put together. Took me two hours!!! That is an hour and a half that I will never get back
This bookcase looks good and will serve the purpose. We had a limited budget to spend on something that would house trophies and this fit the bill. It is made of cheap materials and arrived with small amount of damage, but we were able to fix it and put it together. For the money, I don't think we'd find anything that looks as nice to house trophies and we will probably buy another down the road.
This bookcase takes FOREVER to put together. The parts are well labeled but they just don't fit together well. It took several hours and some gorilla glue to put it together. It looks nice from across the room but if you get close it shows that there are spaces where the pieces just don't fit together nicely. The doors are problematic too for the same reason. It takes al lot of readjusting the metal hooks to make them somewhat fit.
I was looking for a bookcase with glass doors to prevent dust coverage, and I needed a certain size for the spot it was going into. This piece fit all the criteria I had (color not being much of a factor); but admit I was leery after reading all the reviews. I moved on, looked at other pieces, and even looked at different websites trying to find something else. I didn't; and came back to this piece.
Altra Furniture Barrister BookcaseI ordered this bookcase at the end of October. The photograph of it looks attractive and I was only looking for something to hold some files and books. When it arrived the box was very large and heavy and the box was damaged. I brought it inside and when I had time I opened the box and took out one part at a time, when I got to the bottom of the box there was a part that was broken in half.
I had it shipped back to Amazon and ordered a replacement. When the replacement bookcase arrived the second box was more damaged than the first. I looked in the ripped holes of the box before I opened it to save my self some trouble and there didn't seem to be any damage to the product. I brought it inside. When I opened it I again took out one part at a time and wiped each part down with a soft cloth as there are small bits of Styrofoam all over them.
They are very pretty if you don't look close. I ordered two of them and both had broken pieces. The first book case the company sent the part right away. The second one, they were out and not sure when they would get the piece in. After waiting for 3 weeks, we contacted Amazon - they sent another bookcase and we took out what we needed and sent the rest of the bookcase back. I would NOT buy another one of these as it is cheaply made and not wood.
We received our bookcase yesterday, and this is one of the worst bookcases I've ever worked with. The finish on the book case is terrible, and there are several missed drilling holes in many of the pieces. Some of the parts were broken in shipping and other parts were missing. The company was contacted for replacements but replacement parts won't arrive for another 2-3 weeks, leaving us with an un-assembled bookcase for the next few weeks. Do not buy this book case or anything else from Altra.
