Inquiry (采购产品): urethane foam mattresses I would like to know the difference between urethane foam and memory foam that is used in mattresses. Could you tell me the advantages and disadvantages of both? Is one cooler to sleep on? I've heard that some of the foam mattresses become quite warm to sleep on because they take on the body temperature. Please let me know or direct me to whom you think I could get the answer. Also, what do you recommend to put on top of a urethane mattress to make the bed cooler?
