A little over a month with the Climate360 half split, bought just before knee replacement surgery; adjusting the firmness allowed side sleeping again quickly. The foot warming is nice, the adjustable frame sealed the purchase, and cooling still works despite a mattress pad retaining some heat.

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.
Category: Mattress. Type: Adjustable air. Firmness: 0–100 Sleep Number setting. Height: 12–13 in. Notable features: DualAir adjustability, active warming and cooling, sleep tracking.
