Overview

The Ooler Sleep System is ChiliSleep's predecessor to the Cube—it uses the same water circulation technology in a more compact unit. It offers dual-zone cooling with 55-115°F range and app control. Slightly quieter than the Cube but with a smaller reservoir. Still available and a solid choice for those who prefer the older form factor.
