Of the last 5 mattresses I have slept on, this one is the best. It's not amazing. But it is ok. I like the edge support. I like that it is softer than the Helix medium-soft mattress. I like that I don't feel like I'm falling out of bed, and it doesn't overheat me from below (even without the cooling mattress pad I feel like I didn't need to buy--the pad makes the sheets slip when I turn over, so now I don't use it, and so far so good-but we haven't gotten to summer yet). I wish I was getting amazing sleep on it, but given the alternatives we've tried at home and elsewhere, I'm relieved to be getting decent sleep.
