I’m very impressed with this mattress . It’s durable and it’s comfortable. I’m a side sleeper and this is so comfortable that it takes the pressure off my joints as I sleep . It’s also amazingly cool , it keeps my body temperature cooled down . I usually run really hot . It’s got a pillow top to it that gives the perfect amount of cushion. It’s got an 825-coil density system, this supportive mattress gives zoned comfort and pressure relief . Awesome cooling layers and support. Sheets go on easily without a struggle .
