8 hours of standing still (even with good posture) is not the healthiest thing. Movement, using the range of motion of ones joints, changing the posture and alternating load and deload is healthy. This does not happen automatically with a desk job, and even expensive equitment might not be the solution. But there are many different positions one can alternate between (floor: standing, sitting, kneeling, lunging, squatting; chair: sitting upright, leaning forward with some weight on the elbows, reclining with feet elevated, indian style sitting). Additionally one can do some squats and alike regularly, e.g. every time one visits the toilet (aka. "pee, squat, drink"). Making movement an effortless habit ensures that for example the spinal discs get their nutrients pumped in etc.
