ClimateCool bought last year with no regrets: cooling runs on high every night, while their husband sometimes uses medium or low. The mattress cover lessens the cooling slightly, and sheets are limited with a flex top.

Split king Climate 360 lets two different sleepers set their own number plus heat and cooling.
Most owners love the separate settings for each side and the heating and cooling, which lets couples sleep differently. The downsides are the high price, with some calling the temperature features gimmicky, and a few who found it uncomfortable and returned it. Fan noise bothered one.

It's how well reviewed Sleep Number Climate is, out of 100. Negative and mixed reviews take points off, and so does having only a few reviews: a product needs plenty of them, compared with the most-reviewed products here, to reach the high 80s and 90s. It's worked out from reviews only, needs at least 5 of them, and updates as new ones come in.
