In a hands-on review for Tom's Guide, Ruth Jones evaluates the Orion Sleep System, a water-regulated smart mattress cover starting at $2,395 for queen sizes. Jones reports that its dual-zone active temperature regulation maintained a stable, neutral feel and effectively prevented night sweats across a month of testing. Unlike key competitor Eight Sleep, core temperature automation does not require an ongoing subscription. Reported drawbacks include a bulky control hub, continuous buzzing noise, slight added surface firmness, and an optional $250 annual sleep-tracking subscription that underperformed against dedicated wearables.

## Media review

The reviewer found the Orion effective at maintaining a comfortable temperature during their testing and appreciated the dual-sided controls, but noted its bulky hub, buzzing, added firmness and less detailed sleep tracking.
