Bests & Worsts Reviews from Amazon

I got this mattress for our guest room. I've slept on it a few times now (I struggle with insomnia, so I will sneak out of the bedroom to read so as to not disturb my partner), and I find it VERY comfortable. I honestly like this mattress more than the $1500 one in our master bedroom. I am 5'6 and 125lbs, and I find it to be a true medium-firm: very supportive with just enough sink to cradle my lower back. I sleep both on my back and my side, and I have not experienced any more shoulder or hip pain from this mattress than from the plush mattress in our master bedroom. In fact, I think I experience LESS. I've never slept on it with my partner, though, so I am not sure how adding another person on the mattress might change the feel (the old "sink and roll" effect). The edge support is only so-so, which is part of what gives me pause on that. Having just bought it, I can't speak to longevity. Given the price, I don't expect that it would last more than a couple of years as an every-night bed (a bit longer as an occasional-use, guest bed). Still, if a $1500 lasts 10 years and a $300 lasts two, ultimately you are still paying $150/year. I'll update my review if it poops out any time before year 2, but otherwise it's a solid 5 stars from me.
