Build quality is excellent. The seat cover material feels like it will last and it sits comfortably, much better than entry level seats. It has a wide strut base for stability and adjusting the height is incredibly smooth and easy. It stays locked in perfectly once you tighten it. I have not experienced that with other thrones.
The seat has a firm memory foam that in the first month will be a little too firm. After I used it the seat gets more and more comfortable. I often get pinching under my legs because I like to sit slightly higher. I got this in the first week of use, but after time the foam became softer and now it is incredibly supportive and comfortable. I went back to change my review on this subject. Highly recommend.
