The first thing I noticed about the mattress was it's breathability. I travel a lot for work and hotel beds, as comfy as they may be sometimes, really hold the heat in way too much. This mattress stays much cooler so I don't wake up in the middle of the night in a puddle of sweat. This mattress was also incredibly soft and yet just firm enough at the same time. I got an amazing night sleep, and for someone that usually tosses and turns it was wonderful to wake up in the morning and be surprised it wasn't one of many middle of the night uncomfortable wake ups. I can't recommend this mattress enough, I hope it last as long as I do because I don't want to have to part with it.
