Carved Stool Seat

My brother is doing some lathe work for me and I am paying him back with a nice carved seat that he will turn into a chair. I have been looking a different designs, and I was wondering if anyone here could point to the most comfortable seat? I don't need the model as I can do that, but having looked at a few different designs I am not certain which to go with.

Google Peter Galbert Perch Stool.

Looks great, sits great, and he has great videos and or plans to show how to do it. I think even FWW did an article on it....1 year ago?

Thanks Prashun. That is a great looking stool, and I might buy the plan to make one for myself. Using that search term I found a ton of other nice options to think about.
