Mlily PowerCool Firm Sleep System

Experience the Mlily PowerCool Firm Sleep System at The Mattress Clinic in Oklahoma City, OK — a uniquely engineered hybrid and cooling-base system designed for sleepers who need stronger support, firmer comfort, and top-tier temperature regulation. Built with dense ventilated foams, a 7-zone support coil system, and a fan-powered adjustable base that pushes air directly through the mattress, this system is ideal for back and stomach sleepers who run warm at night. If you’d like clarity on which firmness best supports your alignment and comfort goals, optional insight from APRN-CNP Quynh Boerner is available to help you compare models — supportive and never clinical.

Cooling & Temperature Control

The PowerCool Sleep System offers one of the most advanced cooling combinations available:
