A bed cooling system is the cheapest, most effective way to fix night sweats without buying a new mattress. Four serious players in 2026: ORION, Eight Sleep Pod 4, ChiliPad Dock Pro, and BedJet 3 V3. Each takes a different technical approach. We tested all four for 14 nights apiece.

The Lab pick: ORION Smart Cooling. Best price-performance of any active hydronic system, no subscription. Below, the head-to-head-to-head-to-head.

Hydronic vs forced-air cooling — which is better?

Hydronic cools more aggressively (to 55°F vs 62°F) and is quieter. Forced-air dehumidifies and has no water risk.

Will any of these damage my mattress?

No — covers and pads sit on top. The mattress is unaffected.

Power consumption?

ORION ~80W. Eight Sleep ~120W. ChiliPad ~100W. BedJet ~250W.

Travel-friendly?

BedJet is the most portable. ORION and Eight Sleep require Hub setup at each location.

Trial periods?

ORION 30-night, Eight Sleep 30-night, ChiliPad 90-night, BedJet 60-night.
