I brought this to cushion the top of my 
new mattresss. I was looking at those pillow topped mattress when I realised it was easier and cheaper to buy a mattress and then a mattress topper. This topper is brilliant. It really makes the bed comfy and cosy. I love sleeping even more now. Definitely recommend the thickness of this. And it doesn't make you hot, but pleasently warm and cozy and comfortable. So glad I brought it.
