I love this Serta Perfect Sleeper Nurture Night 14.5" Plush Pillow Top Mattres. It is the most comfortable mattress I have ever slept on. Previously I was using a more firm mattress and I thought that that's what my body needed but I was wrong! This pillow top mattress cradles my body and it feels like I'm sleeping on a memory foam cushion that couldn't be more comfortable. It's so comfortable even my dogs want to sleep on it. I've had no issues with getting hot in the middle of the night I can sleep very comfortably the entire time. It's so comfortable that I'm no longer waking up in the middle of the night to switch positions either. I've been sleeping for a solid chunk of 7 hours because of how comfortable the mattress is. I'm so glad I switched to this type of mattress and can't believe I wasted so many years sleeping on a hard firm mattress.
