My husband’s posture has been awful while working on his computer during this Covid-19 work from home crisis. So we read many of the reviews from customers and compared our top three possible choices. This one met all of our criteria! It arrived quickly and was easy to assemble. The arms and seat height are adjustable and the higher back works well for my 6’1” husband. He now sits up straighter and  doesn’t complain about back and neck pain.
