The OOLER is a water-based (hydronic) cooling and warming system, utilizing a control unit/water chamber and a mattress pad that circulates the water through water tubes underneath you. We compared the OOLER to the BedJet 3, an air-based climate comfort sleep system for beds which does not require use of a mattress pad. While both products are effective solutions for sleep temperature control, we tested each in our engineering lab to demonstrate their differences.
The OOLER was installed per the manufacturer’s instructions and not modified in any way.
