there's bedjet. i find that it doesnt work well with adjustable beds though because when you raise the leg part up, the bedjet hose thing tends to slip off.
I suspect the sleep.me chilipad systems (ooler/dock pro) would work pretty well with adjustable beds since they just run a pair of insulated water hoses to a capillary tube network in a mattress pad. Further, if the hose routing didn't work for you out of the box with those you could DIY something else pretty easily since they use off the shelf connectors (https://www.cpcworldwide.com/General-Purpose/Products/Multil...)
