Product description Size:Queen  |  Style:Medium The coolest take ever on affordably luxury was derived from science—the average skin temperature is 91 degrees, but the ideal sleep temperature is 88 degrees. To maintain the optimal sleep temperature of 88 degrees, We infused a phase change molecule called titancool™ on the surface of the Brooklyn Aurora to moderate your temperature: cooling gel beads Liquefy at higher temperatures to deliver cooling relief; those same beads solidify at lower temperatures to ensure an ideal sleep environment. A premium smooth top weave allows the proper amount of cooling to be delivered to you on contact. The result is the most elite sleep experience yet. certi-pur us certified, which means that our mattress is made without ozone depleting, PBDEs, TDCPP or TCEP (“Tris”) flame retardants, mercury, lead, heavy metals, formaldehyde or phthalate regulated by the Consumer Product Safety Commission.
