Be aware that the "firehose" material, is not that of what a firehose is made of. It is very similar to Carhartt's canvas duck cloth...
I'm not even sure what "firehoses" are made of. But if it's heavy duty rubber...no thanks. I hate leather seats, because they don't breathe. And get super hot/cold. I'd imagine rubber would have the same effect.
Just got mine in today. Seems like good quality canvas. I'll install tonight, test it out for a few days, and report.
EDIT: Well, it's not going to work. Their description clearly says it's compatible with side airbags. But the way the bungee cords go right over where the airbags deploy, I really doubt this will work. I called them and they were baffled as well. But great customer service, as they apologized profusely, and immediately said I could return it on their dime. I hope they will make seat covers that are airbag compliant in the future, because I really like the material, and more importantly, the customer service has been great. I will most likely buy the cargo area cover, and maybe the rear seat cover as well.
