Been using a Branch chair for ~2 years after having a cheap ikea chair for 1. Definitely notice the difference. You’re going to want some adjustability, especially with lumbar support and arm height/ width.
Otherwise, the biggest thing to feel better is just getting up every hour or so to move around. I try to go for a walk/ run once a day since leaving retail and losing 10k steps of physical activity.
By that same token, sit-stand desks are nice if you have the spare budget. Otherwise, just get a nice chair and exercise.
The IPO announcement w/ shares being offered to Reddit users. Also, the deal with AI training off of user data without consent. Hard to keep track these days lol.
