Thanks, y'all.
I had been leaning toward Permobil for a few reasons, one of which being it goes up to a 330lb weight capacity. I'm on the upper end of 200s, so it gives me a bit more wiggle room without going to an hd - especially since part of my condition causes exercise intolerance and medicine side effects can be unpredictable.
The rep seemed to be pushing for a Quantum. I got the feeling that it was because he wanted to sell a Quantum for whatever reason as opposed to it being the better chair, so I thought I'd see if there was something I was missing.
He did say that we could make an appointment to go look at chairs, or he could just bring a Quantum over next time he came so that we could see how it would work in my house. I think I'll just call and see if he'll bring the Permobil instead.
