As a side-sleeper with osteoarthritis, finding a comfortable position was nearly impossible. This mattress topper is a gem! The bag it arrives in allows the mattress pad to roll out, easily. It feels like I'm sleeping on a cloud. Your body will mold to the gel comfortably yet reshape when you get up. Personally, I haven't found it to add any heat throughout the night. I plan on ordering more in the near future for guestrooms. Great price-point, as well. Highly recommended.
