I’m too cheap to spend the kind of money the ask for stools and armless chairs that would work. I went to my local Re-Store thrift shop and bought two cloth covered armless chairs with padded seats and backs for $10.00.
One for me and one for a student or jam partner. They may be a little on the ugly side but they were cheap and more than adequate for the task. To each his own.
Totally get wanting a super comfy chair if you’re gaming or practicing for hours 
. I used to cheap out on basic stools too and my back hated me for it. Ended up grabbing a decent office chair with good lumbar support, huge difference. Now I always check comfort and build before buying.
If you’re eyeing outdoor stuff, there are some solid options built for Canadian weather that hold up way better than the big box ones. Saw a few setups that looked straight outta https://wickerpark.ca/ and ngl, kinda makes me wanna upgrade my backyard too 
.
