Product Overview & Review
The Orion Sleep System is designed for couples and individuals who want better control over their sleeping temperature. Instead of replacing your mattress, the system fits over the mattress you already own like a fitted sheet.
Its dual-zone design allows each side of the bed to have an independent temperature setting. The system can cool or heat water between 50°F and 115°F, making it useful for sleepers who prefer different temperatures.
The smart cover also includes built-in sensors that track sleep stages, heart rate, movement, breathing rate and HRV. This data can be used through Orion's sleep technology to provide personalized insights and temperature recommendations.
Orion offers Queen, King and California King sizes. The current official product page lists the Queen at $2,295, King at $2,495 and California King at $2,595. The system includes free shipping, a 30-day trial and a 2-year warranty.
One advantage over some competing smart sleep systems is that purchasing Orion does not require a subscription. Orion Intelligence is available as an optional add-on for users who want additional sleep insights and personalized recommendations
