$55 under your budget

■ The catch — co-equal billing, always
It's mild relief, not real cooling. A fan just moves room air — it can't drop below room temperature the way water does, the airflow can dry your skin, and on a hot night without AC it may not be enough.

The subscription tax
The Eight Sleep Pod gates sleep tracking, alarms and its AI behind a mandatory $199-299/yr Autopilot plan — skip it and you've bought a manual heater/cooler. Chilipad, BedJet, Perfectly Snug and HydroSnooze charge no mandatory fee.
Air can't beat the room
Air systems (BedJet, BedFan) blow ambient room air and cannot cool below room temperature — BedJet won't help in a bedroom over 78°F without AC. Only water systems hold a sub-room-temp surface all night.
Water means upkeep
Water units run a control tower with a reservoir you refill every 1-4 weeks, plus periodic cleaning to prevent buildup — and dual-zone (the config most couples need) costs roughly double single-zone.
