Nice Looking Bookshelf... Lots of Work to Assemble
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I specifically bought this bookshelf because I already have the Heritage Hill desk and lateral file cabinet, so natually this is the one I wanted to add to my office. LOOKS: This shelving unit has the same look as the other pieces to the Heritage Hill collection, so it fits in perfectly to the look of my office. STURDINESS: I'm not a big fan of the side panels because are not one continuous piece. It definitely is not very sturdy while you are trying to assemble it (more on that later) but once it is fully assembled and secured to the wall it seems very sturdy. I do not anticipate any issues. STABILITY: A wall anchoring bracket was included with the product, so when it's properly attached to a wall there will be no concerns over stability. They did not include a drywall anchor with the bracket, so unless you plan to screw this directly into a stud, you definitely need to have a drywall anchor on hand to use. ASSEMBLY: This is where it gets a little frustrating. I am no stranger to assembling pieces of furniture from kits like this. I understand why they have chosen to use the hidden screws and L-brackets everywhere, but it does add time on to the assembly. It probably took me about 90 minutes to assemble this product. The trim pieces that go on to the front of the shelves (around the sides, top, bottom, and fixed shelf) make the shelf look like a higher quality product, and the L-brackets you use to attach them have oval-shaped holes so that you can adjust the positioning of each piece of trim to make everything line up right. You can adjust the positioning so that you don't see any of the unfinished wood or have ugly gaps. Or so I thought! This trick worked fine for everything except the 3 adjustable shelves which also have a trim piece that go on the front, but for the life of me I could not get everything to line up properly. I read this in other reviews so I was prepared to do some troubleshooting and adjusting, but I could not get it to look right, so I just left these pieces off. You really don't need them. It makes the shelves easier to more around and it still looks great. The directions offer some "hints" on what to fix. There was a 1/4" gap between the edge of the shelf trim and the edge of the trim going down the side of the shelf. So the directions tell you to adjust the side pieces of trim to close the gap. Well the problem with doing that is after you adjust the side trim then the other edge of it no longer lines up properly with the edges of the trim piece of the fixed shelf. Another tip: You don't have to leave the thing laying on its back the whole time you are trying to screw in the hidden screws or the L-brackets. You can carefully rotate it onto each of its sides to complete the installation of all the trim pieces, and it actually makes it easier to make sure they are lined up properly to each other the first time. I was just careful doing this because it's not very sturdy while it's being constructed. They also include a touch-up marker in the package as well that really is the same color as the wood finish. I had a couple pieces that had minor scratches on them, probably from shipping. I had great luck with the marker by just coloring in all the scratches and then rubbing all around it with my finger. One larger spot needed this done about 3 times, but when I had finished, I really couldn't tell it was ever scratched, especially at the "normal viewing distance" I would normally see it from.

Best DIY Bookshelf We've Gotten
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
Just finished putting this together and we're fully impressed. The product itself is exactly what it says on the tin, looks just like the photos. It takes a little bit of extra effort from your standard DIY bookshelf just because it has some extra decorative pieces, but we think it's worth it and that's one of the reasons we picked it out. Did have a MINOR bit of confusion since some of the decorative pieces weren't labeled, but they were easy to identify with the instruction manual. Which, let me just say, this is clearly a company who has seen the problems in the DIY furniture industry and has actually taken HUGE strides to make the whole experience easier on the customer and make the product sturdier. There are no bamboo pegs that might not even fit into their assigned holes, no weird turn-to-lock things that may are may not be tight enough to not unlock themselves, no ten different pieces of tiny hardware that barely look different from each other, and NO ALLEN WRENCHES. The entire piece can be put together with a regular screwdriver and a hammer (or just the screwdriver if you can't find the hammer and are determined enough, since you only need the hammer to tack on the cardboard backing); and because the structure's entirely put together with screws and because it's actually separated into two pieces, it makes the entire structure way more stable than your standard DIY bookshelf. The instruction manual is also not only EXCEEDINGLY, PAINSTAKINGLY clear about which way each piece should be facing and what hole you should be screwing it into, spelling it out for you when they can't just point it out on the diagram, or sometimes even doing both; it also comes with a little pre-measured spacer that you can cut right out of it to help you center the moldings on the shelves just right. And just as the icing on the cake, they also include a marker in the color of the laminate to fill in accidental scratches. We are extremely happy with this bookcase, and we'll be looking at Sauder products for future DIY furniture needs.

To be fair this is the worst side the other side is about an eighth of ...
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26", Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I used to work at big box store some twenty years ago and there were two selling points for Sauder furniture at the time. The furniture was 3/4 inch particle board and ease of construction. Well neither of those are the case any longer. I am putting this together and the L brackets that Sauder provides are of the adjustable variety. This lets one slide the two wooden pieces so to obtain a match on their edges. Well in theory, in reality one cannot slide them far enough so one has a 1/4 inch mismatched edge. On part H which is a horizontal trim piece. It is not long enough to cover the trim pieces edges that are below it in the vertical. Those edges are raw wood, but do not worry Sauder has been kind enough to include a brown magic marker so I will be able to cover up that raw wood. I included a photo of one side. To be fair this is the worst side the other side is about an eighth of an inch. And to be even more fair, there should not be any raw wood showing. It is not very sturdy either, the only thing that makes it from really wobbling is the fiber board backing at the rear of the bookcase. My expectations when I bought this piece of furniture was not that great. I wanted to buy a piece of furniture that was fairly easy to put together. I also wanted a piece of furniture that looked okay. This piece of furniture achieved neither one, I would have been better off going to a second hand furniture store and buying a bookcase there. Even if I had to refinish the second hand bookcase it would of been less hassle then this thing. Oh, Sauder I do not want to see a response saying please contact us at 1-800 whatever. When do most people put this furniture together? I would hazard to guess the weekend. When is Sauder customer service open? I can tell you it is not the weekend. If you are thinking of buying this, I would think twice.

Perfect buy
Color: Classic Cherry, Size: L:29.80" x W:12.99" x H:71.26"
I absolutely love this bookcase. It’s stable. It has the perfect color. It’s the perfect height not too tall, but definitely not short. And if it’s perfectly in the corner of my room, the only issue I had with this is the assembly process. Definitely don’t recommend you assembling it on your own. Definitely having someone there to help you assemble it. It’s definitely something I would do. It stores a lot of books, but definitely follow the weight capacity. I didn’t follow the weight capacity and now I have slightly bent shelves. It has good stability.The value is fair for how long it lasts because I still haven’t and it’s still standing.

Difficult to assemble, low quality, but looks nice
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
It looks nice when finished, but it's a major pain to put together. I've assembled a lot of DIY furniture over the years, but this was one of the more frustrating ones, mainly because of the unnecessarily difficult way the finishing slats need to be attached. Also the frame was very unstable during assembly. This bookcase is also not exactly sturdy even when finished. It's a low-quality product in all respects, really, except the nice way it looks. Value for money? meh. Color is nice.
