I've had 5 mattresses in 10 years, 3 of which were foam/blend... This one is the only mattress that didn't leave my back feeling like I'd been carrying boulders all night. The amount of time it takes to get comfortable on this thing is virtually nothing as compared to other beds I've slept on. It is just a well rounded mattress- especially for the price.
Im a chef and spend many lomg long hours on my feet and most times couldnt get to sleep on my old mattress. I've had my T & N for over a month now and have slept more soundly and comfortably than I ever had. I never want to get out of bed, I'd stay there all day if I could.
