Twin XL MLily Harmony Chill 3.0 Memory Foam Mattress
The MLily Harmony Chill 3.0 Memory Foam Mattress is a plush mattress that features a cooling ice fabric cover designed to provide enhanced breathability, temperature regulation and comfort. This model features AirCell Foam to deliver the comfort of supreme performance memory foam, that has been expertly crafted with breathable, temperature-regulating AirCell Technology to keep you cool and fresh throughout the night. The AirCell foam also contains a layer of PCM (phase changing material) that absorbs and releases heat throughout the night to keep you comfortable. The Bamboo Charcoal Memory Foam provides flexible, breathable support that helps regulate temperature, moisture, and odor to help the sleeper achieve the deep, regenerative sleep they have been longing for. An additional layer of Liquid Gel Infused Flex Foam provides even more cooling support for advanced temperature regulation. The Flex Support Foam provides an added level of flexibility and reinforcement by extending support out to the corners of the mattress, giving you a more refreshing night's sleep. If you like the support of a memory foam mattress with the benefits of enhanced air-flow and AirCell technology and enhanced temperature regulation, then you will love the Twin XL MLily Harmony Chill 3.0 Memory Foam Mattress!
