I got a Zinus full from Amazon years ago for a guest bedroom and my daughter was visiting and spent four nights on it and said it was great. Normal. Don't know about a cooling version. I think the only one available at the time was the 12" so that's what we got. My own bedroom has a Nectar queen-size. Most comfortable bed I've ever slept on. Had it for 5-years. Came with a 365-day full-replacement guarantee and a 10-year warranty. The free pillows that came with it are my favorite. Youngest got a Nectar twin at the same time (5-years ago) and love it, too.
