Bought 1 for myself earlier in the year. Works great and super comfortable. So when my husband got a remote job we got a 2nd. Equally good. Helps to have a 2nd person for assembly but not too difficult.
I am 6'0 tall and the head rest is adjusted to its tallest setting yet the headrest jabs me in the shoulder blades (approximately 2 inches too low) instead of supporting my neck and head. The seat of the chair is pretty comfortable.
