Deceptively thin.
You look at the cushion and see a tight nice tight grid pattern on the top. You would expect that kind of support all the way through the cushion. That is not at all the case. The tight grid pattern on the top is about half an inch thick or so. The bottom of the cushion is a much larger pattern with thin walls that just collapses.  The result is a the part that does the actual cushion is much thinner then you think. Makes me wonder if the cheaper models are just as good or better.
