Just tried this out in our guest room last night, we bought what we thought we wanted for ourselves and we definitely want this mattress! We were worried 10” might be to soft for him (6’2”, 220lbs) but nope! Which is great because I wouldnt want to go any firmer (5’4” 145lbs). You definitely dont feel your partners movement and our biggest 
puck was  was the cooling feture. We slept great! Definitely recomend. We will be ordering another for ourselves
