This is a highly personal preference, but since you asked... I’ve been sitting on a yoga ball for about 5 years and it has relieved a lot of back pain I used to have from sitting long periods programming. I alternate to standing and using a portable laptop platform, it was about $25 on amazon. Not the most sturdy, but it’s fine and I don’t leave the laptop on it when walking away.
