This 3-Inch Bamboo Charcoal Infused Memory Foam Mattress Topper - Queen is simply amazing!
It makes my bed so much more comfortable than it was before.
I love the charcoal infusing, it is so much better for your body and helps with hygiene.
The memory foam makes it so my back doesn't hurt at all in the morning when I used to experience back pain regularly. It conforms to my body perfectly and I get a much better sleep.
I would recommend this to anyone. I couldn't go back to sleeping on a mattress without it now. 
If you want a great night's sleep and possibly, help with any, aches and pains, give these a try. They come in many different sizes, there has to be one just for you. I've found mine!
