I liked that this has a high weight capacity, so that it can be used as a seat.  I use it as an ottoman, and it is the perfect height for me when I am on the couch.  I have fallen asleep while using it as an ottoman, so it is great for that purpose.  It was so easy to put together (takes less than a minute once the package is open.  It also seems to be constructed well.  My only complaint, which isn't really a complaint, is that it does not have sliders to move it around the floor, but I don't know if that would even be possible with this collapsible design.
