I slept my first night on this mattress last night, and while I ordered the medium comfort level mattress, straight out of the wrapping, it feels a bit firmer than that, but that could very well be because I’m not used to the mattress yet… I’m sure as time goes on the mattress and I will acclimate to each other, and it will conform to my sleeping styles. It is a very comfy mattress, with good side support, as I am not a small person, I weigh 350 pounds and stand 6‘2“ tall, and the sides support me well when I sit on them to get dressed in the morning…  The pillow top addition adds just the right comforttothe mattress…. I am typically a hot blooded person, and prone to night sweats, if the temperature is above 70°, and lately it has been very hot here, And last night the mattress was nice and cool even with a 78° temperature inside the house. I would recommend this mattress to all of my friends and family
