PURPLE: I don't know about the safety of any eggs, but my back-side thinks it's okay.
To be blunt, it is not what I expected and it isn't exactly what I wanted. First, it is heavy: yes, I bought the biggest one that is double the height, but it was still heavier than I expected. The upside to this is that it doesn't move around much on the seat. Second, the shape is very specific and the cover is made to fit that: I had the cover on backwards at first and it was less comfortable. The upside is that with it corrected, it's fairly comfortable.<br /><br />THE MAIN REASON I BOUGHT IT: to deal with a hot butt. I have used many other types of seats and the only one that comes close to the heat dissipation of this Purple seat is a sobakawa pillow. But even this will get swampy if you never move. I find that I still have to adjust about every 20 minutes, but here is where it succeeds: I stand up and stretch and then sit back down (20 seconds or less) and it has completely lost all the heat! Most everything else would still be hot, but the Purple seat does the trick every time!<br /><br />Summary: Is this the most comfortable seat ever? No. But it is better than most other things out there and with someone like me for whom heat in the seat is an issue, it works wonders and I would recommend the (high) price.
