If your legs are falling asleep it probably means your seat is too high. If you lower it, that should give some relief. As far as a cushion goes, I can’t help too much. I had one for my last chair and it worked fine, but I ditched the chair for an Aeron and haven’t had any problems at all. As far as I know, any cushion is gonna be just fine. Padding is padding.

Was gonna say a cushion is probably not the solution to OPs problem, they’re either not using their chair correctly or the chair is bad
