ComforPedic from Beautyrest 10-inch Twin-size Gel Memory Foam Mattress Set| See All ReviewsI purchased the ComforPedic Beautyrest memory foam mattress set about 3 weeks ago and have been very pleasantly surprised at how comfortable it is. The "plush" softness is perfect to prevent body aches, but not too soft so that you feel like you are in a hammock. I like that the edges are firm. It feels comfortable to just sit on the edge of the bed. Most of the mattresses I was looking at did not have this feature. I'm very pleased with my purchase of this mattress.
