Don't buy!
I purchased this king mattress for the cooling factor & the fact the company had a 100% refund policy if not satified after trying for 30 days. I even purchased the mattress protector & ghost sheets. My boyfriend & I were excited to try out. Unfortunately, we both had terrible nights sleep. Of course, I figured it's new & were getting used to it. But, it continued every night where we were both hot & it was just too soft for us. I emailed the company as requested & got asked numerous questions..what sheets I'm using, temperature of the room, home. I answered with the main reason that we were both so hot & that was my initial focus on this "coolest mattress in the world", but was told being too hot is not a reason for a refund. I wish I would've done a better google search of this company as I would have saw the numerous complaints just I have encounter. I'm still trying to get ahold of someone in management, but have not been contacted. I'll keep continuing to fight this issue, but I highly suggest you use another company.
