This chair is the best! I’m petite and most desks are too high for me, which means even at the tallest level a basic desk chair doesn’t left me up high enough. Which turns into all other sorts of ergonomic issue, arms hurting using the mouse, neck hurting due to arching up higher, hips hurting, you name it. One can only add so many pillows to a chair for height! Anyway, this chair solved all my problems and the arms lifting up and down are a bonus! So is the bar to rest your feet on! A friend of mine ended up getting one after she sat in mine. Working from home now, as many are, comfort is huge! Love the desk I got from Wayfair too!
