This is an outstanding mattress that hits all of the "sweetspots":  Soft yet firm; cool; incredibly good motion separation; very economical; delivered quickly; easy setup.  I'm an awful sleeper who is bothered by and also bothers anyone in the same bed, and so often sleep alone in the doghouse.  My wife and I had to share the Sweetnight Twilight Queen at an AirBnB and were amazed how well we did, both getting full nights' sleep.  I didn't even wake up when she got out of bed in the morning, a first.  We immediately took down the make and model and ordered it.  Now my doghouse has a queen bed in it.
