Wow... I can really fly across the hardwood floor in my home office in this one ...and do lots of spins too. ( that’s the fun part) when it comes to working at my desk it is fine but I wish it had a front and back adjustment so I could modify the tilt of the seat. I find I am putting a pillow under my thighs or at back to get it just right. The up-and-down function in the armrest height is perfect. I am happy with it and liked the price
