Silver chill plush king. Great support and super soft! I'm using the sealy charcoal infused sheets along with it since they are a low thread count and are moisture wicking. The chill effect does get minimized by the sheets and only last a little while. That being said it's not hot like our old all foam mattress was and using a linen quilt also helps with airflow/temp instead of a comforter. There is a very slight stuck in the mud feeling but again it's nothing compared to our old foam mattress Having springs again is also nice when you're having fun with your partner lol. We are both just shy of being 6' tall and weight range is 140-200lbs. All in all happy with the purchase and I'm hoping it's structural integrity holds up since it's new!
