Hi, I had a couple of questions about this chair. Does it have airbags in the seat, or just the rollers? Are the hip airbags tall enough/angled such that they push down on the top of your thighs to enhance the glute massage? This is something I really like about the JP3000, I'm wondering if it's similar this chair. How would you say the massage compares to the JP3000 and the Ohco M8 Neo?
