The reviews for this bookcase were not all good, but the style fitted what I was looking for so I took a chance. So glad I did. The supports are very sturdy and it came with fittings to attach the bookcase to the wall if you wanted more support. I am using it freestanding as it is sturdy enough for where I want it and what it will be used for ie: lsmp, phone and Wi-Fi router. It would not hold a lot of books because of the corner shape of the shelves, but for what I bought it for it is perfect. It looks attractive and does the job perfectly for me!
