Technically, this is the second bookcase I've bought. The first I bought from Wayfair, and I absolutely love that bookcase. The Mission style bookcase sold here is the EXACT same bookcase, but costs nearly half of what I paid on Wayfair. I wasn't sure it was the same bookcase, but I saw the pictures and matched the dimension, so my fingers were crossed it was the same. To my delight, when I opened the box and saw the assembly instructions were the exact same, to the letter, I did a little dance. The only difference I've found is that the included hex wrench was a bit shorter than my first bookcase's. The wood, screws, caps and accessories were all the exact same.That being said, my identical bookcase was bought about 6 months ago, and it's extremely sturdy. I have a ton of books on it and it doesn't seem to put any strain on it. It's beautiful and looks like I paid 3 times than the actual cost.Some reviewers here have really nitpicked the hell out of this bookcase, and they obviously don't have a clue how expensive solid wood bookcases that don't have any flaws really cost.Helpful Hints: I bought this bookcase twice in Espresso, which is a dark brown and any nick will show the bare, light wood under the finish. To fix this, I just take a black permanent marker to cover it and immediately rub that area with a dry paper towel. The marker ink sinks into the wood and wiping it immediately removes the marker ink that gets on the finish. The key is small areas and immediately wiping/rubbing it with a paper towel. I'm sure black or brown shoe polish would work just as well, if not better.A good tip learned from Wayfair reviews and used on my first bookcase assembly - use wood glue on the wooden dowels that are on each end of the back shelf braces (the long skinny pieces with wooden 'pegs'). Besides the pegs, also glue any loose slats on the sides. Some will be easy to move and will show the bare wood that was hidden until moved. This makes the bookcase extremely rigid and much stronger.The shelfs do come with pre-drilled pilot holes for the hex bolts, but before you start assembling, screw bolts into the pilot holes to make threads first, then remove the bolts and do the normal assembly. This will help with balancing pieces and getting screws started much easier.Some complained about the finish. Yes, it's not some really layered polyurethane finish. It's wood stain and light semi-gloss finish. If you want it to shine, just use a can/bottle of regular furniture spray wax. It'll make it look like it has 3-4 layers of glossy finish. Again, this bookcase is half the price of similar bookcases, so expecting this to have the same finish as a five hundred dollar shelf is just plain ridiculous.Update June 5th, 2023:I've bought more of these bookshelves, 6 in total now, and they are still just as amazing 3 years later as when I bought my first one. I'm almost tempted to buy one now just to store away in case I need one later in life, because the current price now is just so tempting. Again, for the price you will not find a bookshelf that is sturdier, more beautiful or spaceous. Still a 5 star rating after 3 years!
