I sat in some of those seats. I didnt like them at all. I am a skinny kid 32in waist 5'11 175lbs and they were too tight on me. I didnt sit in the microsued's just the regular seats. The material will pill and frey in under 3 months-I work at my families dry cleaners and I know fabrics.
To be honest if I were to do it again I would have either gone the route I went Sparco Torino 2's or I would have gone with the affordable yet durable Summit/Jegs seats.
It comes down to what your going for with the budget you have to work with.
Personally my seats rock. They are not in yet because I am waiting for a carpet but I have been sleeping-yes sleeping! in my passanger seat. Why? Because its my passanger seat and I will never get to enjoy it after I install it. I have it on my bed and I watch F1 races...call me crazy. It is very comfortable and supportive. To someone much larger than my build they may be tight.
Like said above, test every seat you are considering out before you buy. I was so close to getting the Corbeau CR1's without testing them. What a mistake that would have been. From what I have seen if you go with them you are just paying for the name and bragging rights disregarding comfort and functionality.
If you are curious, everything (belts, brackets, seats, shipping) came in at just a bit over $1900-No Regrets.
