I'm not sure about a cooling system, but heated blankets/mattress pads exist for pretty cheap ($10ish.)
Anyone know if there's an inexpensive way to cool a mattress? I found the "ChiliPad" for US$450, with discount codes taking that to $336, which is still way more expensive than any heating pads.
Everything else I've found just seems to be mattress pads with cooling fabrics, which just feel cool to the touch and don't actually cool you down.
I would have expected some plastic hose meshes to exist, that could be plugged into any sort of cooling system (be it pelletier, compressor, evaporation, or just radiator based) trough a closed-loop "watercooling" system, but couldn't find any. Such a mesh could be built into the mattress itself.
I would expect waterbeds to be easier to regulate as well, as I imagine they have a higher thermal conductivity. This could allow to place the cooling apparatus underneath, and make it something like a regular fridge radiator.
Actually, I found a few commercial products for the first idea while researching the second, among which a "mycoolbuddy" mesh that seems to retail for around $60. To be fair, cooling is always a lot harder than heating, courtesy of thermodynamics.
edit: seems like BedJet does it trough air cooling (~$100), which is interesting as well (and they made a fun marketing video, btw).

I dunno if you've ever slept on a waterbed, but you probably would not want to have a cooling system. The large heat capacity of water means that they act like a giant heat sink, they're actually pretty cold as is. It's the same reason a pool full of water at room temperature feels cold when you jump in.
Chilipad is a complete lifesaver. I am a hot sleeper (sweat in a 55 degree room with just a sheet), and it can keep me so cold that I shiver if I don't turn it up.
It's a super chintzy product, not well made at all, but I am unaware of any substitute for it at any price or quality.
