So far, so great. This bed is very comfortable. My hot sleeping husband has been sleeping cool, which never happens. If you’re reticent to buy a memory foam mattress because of the temp, I think you’ll find that this one does regulate temperature very well. My husband no longer sleeps with pillows under his legs to help with back pain as the mattress provides stellar support. Very happy with this mattress. Would give 5 stars if it was a little less expensive.
