Aside from the increase ride height, I have no complaints about my TMI foams. They fit just fine under my stock seat covers.
I mean, they could have just built them the same height as the stock ones....then people would complain that they aren't any better than stock and offer the same crappy support?
....and you haven't gotten your stuff back from the upholstery shop. Might wanna hold off on the praise till you see what they look/feel like.
