I've got two, one is a Comfort Zone I think. The other I'm not sure who made it. I'm 6'5" -350lbs so I just like the added room to be ableto sit comfortable. The only thing that bothered me is the seat hieght in relation to the foot rest was too short. After about 45minutes- 1 hour my knees started to hurt and I would stand up and streach them out. Too much movement for me. I built a "booster seat" out of some treated lumber to raise my seat hieght up 5 inches. Much better for us taller guys.
