It arrived earlier than projected and is thicker than I expected. I have a very firm mattress and needed some cushion because my shoulders were starting to ache and I knew it was from the mattress. I had a pillow top that ended up sinking in the middle (I will never buy again) and my daughter had a fairly new mattress that she didn't want. Now I know why. This was the perfect solution other than buying a new mattress. My shoulder pain is easing away and I sleep better. I have hot flashes and it doesn't seem to hold anymore heat than a regular mattress would.
