Staples had one or more of the mesh-type chairs and I was tempted to get one. It seemed comfortable and I thought about the cooling benefit of the air flow that you mentioned. Making a final decision was difficult. They had many models of chairs and, of course, they all feel a little, or a lot, different.
That visit to Staples on June 6 was not the first time I had looked at chairs. But, I was really getting fed up with the old chair. The underlying seat cushion material (presumably a foam type material) had lost it's elasticity, so sitting on it felt almost like sitting on a board. It felt hard. The new chair has a higher back, with better lumbar support than the old chair. The chair back actually comes up to about shoulder level when I'm sitting in it.
I looked at one chair in the store which had unique features, features which I think more chairs should have. It had three handles on the right side under the seat, whereas most chairs had one. One of those handles could be used to adjust the tilt angle of the chair back. And, I believe another one allowed the user to adjust the tilt of the seat. This just makes good sense, doesn't it? How many years now have car featured adjustable seats? I doubt there's a single car made today that does not have adjustable seat backs.
