The chair seat felt low when I bought it but I just thought that was the style of this model.

After a couple days I started to think something was up. I can't remember exactly how many but the seat has either four or five springs. I was able to push down on the seat and could feel the center springs push down a lot further and not spring back compared to the springs at the front or the back of the seat.

When I flipped over the chair, you can unzip the fabric. I could see a split on the foam where the spring was broken and the foam over stretched.
