I am a fairly petite person (5’3” around ~115lbs) and I work as a psychologist. I sit at my computer around 5-7hrs a day (minimal typing, mostly face to face zoom call style).

By the end of the day my hips are aching as tight, and I feel my lower back rounding (needing some lumbar support I think). I’m also a runner, if that means anything related to how my body functions while sitting for a full work day.

I’ve also sat in either my dining room chair (don’t judge me too harshly) or in a crappy old computer chair. I am ready to actually spend some money since I spend so much of my time sitting. Ideally Amazon because I want to try a chair and be able to return it if it isn’t a great match.

Thanks in advance for any guidance!

I am a college student and I have a in person summer internship, so my desk chair at home doesn't get used much or for very long periods (most just for gaming and occasionally getting work done, but I'm never really in it for more than an hour or 2 max)

When I moved for college my mom got rid of a bunch of stuff in my room (including my cheap IKEA hard plastic chair, which I hated but again didn't really matter) but basically I just need literally anything and just need something quick on Amazon. $100 max budget, but I saw some options around the $50 price range which would be a lot more ideal. I understand I'm not going to be getting a good chair for this price, but what's my best option for something that's going to be somewhat comfortable and ideally not fall apart in a few years. (Are the Amazon basics chairs any good? Anything in particular I should look at or avoid, I really don't know what I'm looking at here)

Edit: I know buying a better used chair is the best option, but I have an Amazon gift card and don't really feel like looking for one used
