They are comfortable for me… I DDed them and I’m an old man, you should be ok.
For a very low car though you do have to get down low (not Flo-Ryda low though) and slide over into them because the thigh bolster is higher than stock.
Doing it in a Miata with the hardtop on takes a bit of practice but it’s not a big deal. Other cars, it shouldn’t be a big problem.
They’re not going to like cradle your heiny and soak up bumps like you are floating on a cloud, but do offer good lateral support and are good reliable seats, not a brand X seat where you’re not sure about the quality.
