Right now I am struggling because the mattress seems to be to build too much heat for me to sleep comfortably. I did not use a mattress cover and there is plenty of air flow under the mattress. I have only been sleeping on it a week, so I will give it more time to see if I can adjust.
Quick delivery, well boxed and price was very competetive. The mattress is very comfortable and almost zero outgassing. It was 1/3 the cost of my other mattress. I will buy one again.
