Very comfortable and helps with pressure points for side sleepers. I like a soft mattress that lets you sink into it a little and this mattress does that while still giving good support. I am no longer waking up with shoulder pain and it has alleviated hip pain for my wife. I'm also a hot sleeper and this mattress seems to sleep fairly cool which is great. My only complaint would be that it isn't so great with motion isolation and it's a little on the expensive side.
