I am a Stearns & Foster mattress loyalist. Their value is immeasurable. I am a side sleeper who prefers the firmest mattress I can find. The firm Estate mattress delivers excellent supportive comfort. My first S&F lasted 20 years and my new firm Estate mattress is proving its worth for fabulous sound sleep. The quality careful construction of my new firm Estate suggests this fabulous mattress will serve me well for another couple decades. The mattress is very heavy but with the handles I can still manage to move on and off the platform bed by myself. The reinforced side walls are amazing and will hold up to sitting on the bed edge when necessary.
