Excellent alternative to water-based cooling, with a catch
I've had the Smart Topper for a few months now, and it has definitely transformed my sleep in a positive way. My usual pattern is - wake up between 3 - 4 am (wide awake), cool myself down with ice packs/an AC unit, go back to sleep for 40 m - 1 h, repeat until morning time. The worst part is waking up over and over again - the second worst part is needing to cool down & wind down repeatedly throughout the night. While the Smart Topper didn't solve the first issue (I still wake up repeatedly at night), it did solve the issue of needing to constantly get up and use cumbersome ways of cooling down. Now, when I wake up I just reach for the control panel on the unit, lower the temperature significantly, let myself cool down for ~10 minutes, and go back to sleep without ever getting out of bed. The unit differentiates itself from other similar products on the market by being air-based rather than water-based. I find this super convenient, as I've owned a cheap water-based cooling pad previously which would easily mould. There's one important catch, however. Unlike water-based cooling pads, the Smart Topper has some real thickness to it. I assume it needs to be that way in order to give space for the cool air to flow up the pad so it can reach every part of your body. The problem with this design is that the pad loses its shape over time, forming wells near the heftier parts of your body which never poof back out. This hasn't become a huge problem yet for me, but as I said, I've only owned mine for a few months at this point. If the pad continues to deform, I could see it becoming a problem from a sleep posture point-of-view.
