Bought the Cal king regular mattress back in November although I was skeptical of a bed in a box. I’m an athletic build at 5’10 and weigh anywhere between 205-240 depending on if I’m in season, and this bed has done wonders to help me in recovery. The wife and I have slept great every night since we got it!
I had slept on one of these previously and always slept well. So when it came time to buy a new mattress, I went with what I knew. I sleep hot so any cooling was appreciated. It's very supportive. It shipped quickly and in a box that makes it "easy" to move around to where you want to unbox it. (Easy being relative but compared to other stuff I've gotten in boxes, this was a breeze.)
This mattress is amazing!!! It's hard which i love, and comfy enough to put me right to sleep. I've been sleeping on it for almost a month now with no complaints. I was nervous about switching to a foam mattress from a traditional one but i don't regret it one bit.
