Good Concept, Too Small for my Application
The concept is good and the quality seems good.  Unfortunately, the pad is not as large as it could be.  Measuring these things is a bit of an approximation due to the taper and shape.  However, mine seems to measure only 15" X 17" on the bottom, which is the largest surface.  The seating surface is smaller due to a taper in the design.  My office chair seat cushion is 20" X 20".  If this were a true 19" X 19" it would be very good.  I understand that not all chairs and users will require the same size.  More sizes should be offered to better suit more applications.  As it is, the too-small size causes pressure lines where the cushion ends and I extend out past the cushion.  If I keep my knees tight together, the problem of pressure lines on my legs is less, but not completely eliminated.  A bigger cushion would allow the user to settle down into it and it would wrap around the person, distributing the pressure.  The best solution is to get a better chair, not a cushion to try to remedy a deficient chair...  $85 is a good downpayment on a truly great chair.  In my case, shipping a new, expensive chair to Afghanistan to be used for only a few more months did not seem to be a good choice, either.  Although, my replacement might have appreciated it!
