We’ve had this chair for a little while now and I figured I’d say something about it. Took me a while to actually buy it. We both retired a few years back and these days I try not to spend money unless I’ve really thought it through. My wife was already on board way before I was. Before I ordered it I did send them a couple emails, just had a few questions. Honestly didnt expect much, figured I’d hear back the next day or somethin, but they got back to me pretty fast. And then again when I asked another thing. Not those generic answers either, felt like someone actually read what I wrote. That kinda stuck with me. Delivery was another thing I was a little worried about. Big heavy chair and me and my wife arent really in the business of hauling stuff around anymore. I was already thinkin I’d have to call my son but they ended up bringing it into the house which helped a lot. That part alone was worth it to me. As far as the chair, yeah we’ve been using it most evenings. My back tends to act up later in the day, probably from years of sitting wrong or who knows what, and the heat on the back actually feels real good. Not too much, just enough to kinda loosen things up. I will say too, it feels roomier than one we tried at a store a while back. That one I remember thinking “well this isnt gonna work” after like 15 minutes. This one I can sit in longer without feeling all cramped up. Anyway, I’m not gonna over sell it. It’s a good chair, does what it says. But honestly what stuck out to me was how easy everything was with the company. These days that matters more than it used to. Funny enough, neighbor came by the other day, tried it for a few minutes and next thing I know he’s asking me where I got it. So yeah no complaints here. Glad we ended up getting it.
