I'm 5'3 petite female. I sit for 6-8 hours a day in my home office this is a very sturdy task chair designed for extended sitting. The key to finding the best chair is to make sure you get a chair with a rating for what you utilize it for. The mesh is supportive both on the butt and thighs and back. The seat bottom hits at a nice area behind my knees for a shorter petite person a lot of my other chairs had too large of a chair bottom and my knees were not supported. The lumbar support helps my lower back the head rest is nice because it has 3 tilt options. the arms also have adjustability at 3 different levels. The chair high has a nice range to move it up and down. It also has a tension feature that allows you to be able to lean back or keep the chair from leaning back (like rocking back n forth). I personally keep the tension tight so it doesn't lean back n forth to have good posture. All and all great chair for the price for extended sitting.
