Thank you for the recommendation.Where are you based? I saw a half decent one in Costco a while ago for about £120.
If you can get one where the seat and back sections are adjusted simultaneously as it automatically gives you the best angle. Old style ones have two separate adjustments and aren’t as good.
I live just outside of Washington, DC and have a Costco membership.
I’ll be honest- I hadn’t thought of them but probably should have. They sell everything.
