We got the bed during the summer. The bed was very comfortable due to the cooling layers. We tried other beds that were hybrids but it didn't work out because of the heat. Not so with this bed.
It took a little breaking in but we get a great night's rest. There's great motion isolation.
The sides supports could be better but it's good enough to keep me from falling out of bed. In the end, we both love the bed.
I have Ehlers-danlos, so it is hard to find anything that is truly comfortable and helpful for our bodies and sleep. So far, this mattress is amazing. It is just the right amount of firm and give at bony prominences, and it really is cooling... I am praying it continues to please.
