The reason for the lower rating is that for one the chair itself when you get it is not great. The foam that is used on the inside of this one is terrible. It's basically just foam chunks but the issue is that they don't expand at all. Even if you leave the chair for 3 to 5 days after opening as I did and it did nothing at all but stay flat as it did when coming out of the box.

I had to actually buy the bean bag beads from here in order to fill it up and get it good enough to use. Now it's great but upfront I feel that you shouldn't have to do that at all. It should be filled with those from the beginning and you shouldn't have to do extra work or spend more money.
