Bests & Worsts Reviews from Amazon

I bought a very firm, high end memory king sized foam mattress about two years ago, and despite it being "perfect" for my body type and stomach sleeping, each morning, I'd wake up with sore back and hips, sometimes with a numb arm, and the sense that my sleep quality wasn't as good as it ought to be. I chalked all this up to being overweight, middle aged, stressed, not enough exercise, etc etc. Then I got fed up with feeling crappy all the time and decided to make a change. I wasn't eager to drop $1500 on another mattress. So, coming off an online review for this product, I decided, "what the hell, let's give it a try, it's less than $80." I was skeptical, to say the least. I'd had foam toppers before and always found them to be less than satisfying. I have one word to say about this one. Flipping miracle. (Ok, that's two words). I've had it on my bed for four days. The first night, I laid down and felt muscles relaxing because, for the first time, they felt gently cradled. This morning I woke up and had no pain at all, felt rested, rejuvenated, cheerful. I noticed my posture is better and I feel taller. It works well in any position. I tried side sleeping last night and had zero problems. For me, it's just thick enough without being so thick that I sink into it and can't turn over. I'm a little worried that long term use will compress it and make it less useful, because the foam is very light and easily squished. But even if I have to buy one a year, that's about $0.21 a night for a huge improvement. I can live with that.
