UPDATE: Caveat Emptor & Mixed Feelings
UPDATE: 7/26/2020<br /><br />Sitting on the Purple Ultimate Seat Cushion for a few months relieved some stress on my lower back but not by much. I also began to notice that I started developing back pain in the middle of my back, so the pain shifted from my lower back up to the middle of my back. I also noticed I developed stiffness in my neck and it would begin to make a cracking noise when I bent my head back.<br /><br />Worrying that I was making things worse and not better, I actually had to reverse the divot from the back of my seat to the front which improved things quite a bit. I decided to test this by going back to the divot side and my same neck problems occurred again. I'm not sure what the problem is with the divot but Purple probably needs to create another version without it. I don't understand why all their other smaller seat cushions don't have a divot but this one does. I think it's time they researched and redesigned the Purple Ultimate Seat Cushion for better ergonomics and back support. Overall, I am happy with my purchase but they could do a lot better in my opinion.<br /><br />-------------------------------------<br />I purchased the Purple Royal before opting for the Purple Ultimate. The Purple Royal was a nice cushion with rounded edges which I appreciated, but it was just too small for my body. I returned it and decided to get the Purple Ultimate directly from the Purple website since this item has been showing as unavailable for months. I thought that was awfully strange.<br /><br />So, I have now been using the Purple Ultimate for 3 months. I liked it at first and it made sitting more comfortable but I was hoping it would help my lower back, ankle and foot pain. It really has not helped at all. Also, the divot for the cushion doesn't really allow you to place on a seat that also has a cushion. It has a tendency to slide forward and my body ends up sitting behind the cushion. It's impossible to get it to lay correctly on my office chair. I have to stuff it underneath the back but it doesn't really work for very long. I also noticed that it causes pain and stiffness in my neck. So I now have neck pain where I get a cracking noise in my spinal column. I don't know if this cushion has made things better or worse.
