Had one. Lost it in a divorce. Miss it every morning. (The bed, that is).
My sis and bro in law had one and loved it til it starting leaking air I think. They also found the black mold in it and it was disgusting! They now have an icomfort and they say they like it a lot more.
Especially when you figure on the lifespan of a regular spring mattress is only 5 years.I bet the factory would've warranted the product. We've had a sleep number for over a year and absolutely love it. Wouldn't go back to a regular mattress. Pricey at first, but as already pointed out a long-term cost comparison reveals that it's fairly reasonable.
I've been thinking about getting one of these too. The girl and I have vastly different preferences of bed comfort.
