Tillet seat fit

[JREmira]

I’m interested in Tillett b10 seats but would like to sit in a regular sized seat before ordering. I recently sat in an xl and it felt good but I’m looking for a snug fit with maximum lateral support but not uncomfortable. Does anyone in the Philly area have a car with these and would be willing to let me check them out? I’m 5’11 and around 175 and drive the car on 1-2 hour back road drives. I guess I could go either way but nothing beats actually sitting in each before buying. Thanks!
