The best I've found
I thought, why not? Nothing else has worked. I even got the Broyhill big Man's Chair, and a month later I was back in agony from leg numbness. I have a lot of health problems( MS, Arthritis, Spinal Degenerative Disease) so I need stuff that works, and until this cushion nothing did. Now it's not a cure all. You can't expect perfection but like I say it is the best. The only trouble I always have is that my dogs like to sink their teeth in it and ruin it, but that's far from the manufacturers fault. A word in addition is that it took some trial and error to adjust the air level. A full cushion is NOT best. Like their literature suggests, go with a low volume. You'll be surprised at how much a puff or two of air will do.
