Excellent storage unit for narrow spaces. Like the adjustable feet for uneven floors. I also like the height, provides great spacing between shelves for tall items and the shelves are deep enough to hold a lot of items. I'm 5'3", so reaching the top shelf is a stretch, but I'll just put some greenery up there or use a small stool to reach items safely (worth it for the spacing you get). 

If using the shelving unit in the kitchen (or anywhere for that matter), I would recommend getting the baskets featured in the picture (two for $22). The baskets fit the shelves nicely and are great for things like breads and bagged chips in the kitchen and in the bathroom, for holding hair products/dryers and other accessories for examples. Good quality weave and sturdy construction.
