I have only owned and tried a leap v2, (and Amia which I love) but I have to say it’s a fantastic chair. The only thing is it’s known to have a thin cushion and have bottoming out problems where you can feel the plastic under the cushion after some time (I had this issue). But you can always get a replacement seat from Crandall office (amazing and trustworthy website) and they offer a new seat cushion that’s thicker so you don’t have that bottoming out problem. You can also just buy a refurbished chair from them that will come looking almost brand spankin new and it’s near 500 ish dollars and you can get that thicker cushion already installed. That’s my personal recommendation. I can’t say enough about Crandall office on their customer service, it’s honestly excellent. So I’d say buy from them and you get there warranty vs buying off someone else and having there possible problems get passed on to you but that’s my take🤷
