By far the best mattress I have purchased. It is so comforting to sleep on. I paid for the extra cooling and it is worth it. My body temp runs hot and I don’t have the night sweats as I have with previous mattresses. I recently stayed in a very nice hotel. While the bed was comfortable, it wasn’t my Helix mattress and I missed my bed while on vacation. The hybrid technology is definitely the way to go. I feel embraced yet I don’t feel stuck while laying in bed compared to the immovability of foam mattresses.
