Sleepyhead Memory Foam Mattress Topper

I really hoped to love this mattress topper. And it may come in handy as an air mattress topper for guests. But, I most certainly wouldn't have paid $225 (queen) for guests, just a few times a year. My pillow top mattress is either reaching it's end of life, or I've aged into needing something different. I had spent the night at a friends house a few months ago and got excellent sleep. When I commented on the great mattress, she said it was actually not all that great, and just had a cheap memory foam (2 inches, I think) on top. I've been shopping for just the right memory foam option, and willing to spend a little more if it meant good sleep again. But, unfortunately, this didn't provide any improvement. It would probably still be a great mattress topper in the right circumstances. Just not for what I was trying to accomplish. It's not uncomfortable, per se. But, it doesn't absorb your body like a memory foam mattress. When I'm on my side for a while, I get the same aches on my hips and need to turn over. On the pros: It does not sleep "hot." I buy cooling sheets, and run my winter thermostat at around 66. So, I like it cool. And this did not cause any heat issues. Cons: It doesn't quite stay put after a few nights. I sleep solo, so it's your pretty basic TV viewing and sleeping efforts. But, being that it is on top of a pillow top mattress, it shifts around, where it's a couple inches off one edge each night. It certainly would not stay all that put if your bed usage were more...active. It never seemed to fully expand on the ends. Maybe that is part of what is causing it to shift on me when I sleep. I'm sure this could be a great addition in the right circumstances. Maybe for a dorm room, or on top of a very firm mattress to give it some cushion. But, if looking for that experience you see in the commercials of a side sleeper where the foam absorbs all the air space of your body and gives you total support - at least for someone in their late 40's - I did not find it to be any help for that.
