A standing desk and a "premium" chair (Steelcase Leap). A lot of people I talk to about spending $800-1K on a chair rebuke the very idea; while they themselves are on their second or third IKEA MARKUS ($300/per); while offering a far worse user experience in the interim. Depending on where you live, there's also an unusually large supply on the used market due to telecommutting. There's a saying: "Spend money on what separates you from the ground." Meaning shoes, beds, and chairs. But I'd also say a desk that is supporting your hands, wrists, and arms should maybe count. Standing desks can help a lot with sitting too long in one position, in particular if your work has times when you don't need to type you can switch to a non-traditional handheld mouse (e.g. ELECOM Relacon), and stand more naturally. YMMV of course.
