I just bought a memory foam mattress of sorts.....I kinda put one together to save some money, but so far it has been awesome. I have slept on it for four knights now and it has made a huge difference in my sleep. I no longer toss and turn all night long and my back hasn't been sore in the morning for the frist time in years!!!!
If you have a back that is bothering you I would definitely suggest getting one of these.
Here is the thread that got me hooked on getting one of these:
Super long thread. Waring it is about a year and half old and is really long, but worth the read if you are looking at getting one of these.
Here is my review after my first nights sleep and how I came to put the bed together:
First night review.
I literally sleep without moving the whole night practically.....and I feel hundred times better in the moring, like I actually slept.
The downside with teh mattress pads I bought is that they were a pain to get opened up and setup. They come oversized slightly from where I bought them and it was a pain to cut them down to size a little better. It was only about 1" to big lenth wise and 2" to big across and I probably could have left it but it bugged me that it didn't line up with the mattress perfectly.
