Posture Stools

[22]

I thought I'd injured my shoulder on a rowing machine, and then thought an exercise bike. I've done neither for months after (unrelated) surgery and it's still increasingly troublesome. Physio (through work health insurance) thinks it's top-of-bicep related, it's painful at certain points - but sleeping being one of those!

I think it might be RSI or bad posture although I have a standing desk. It's one of those adjustable desks. I'm standing for ~80% of my time at the computer. I've tried adjusting it so my elbow is at different angles. Today I've chucked it out and I have a screen on a desk. I'm now thinking I need to look at my sitting posture so happy to be recommended a decent posture stool. Sensible budget for something people have used.
