TEMPUR-LuxeBreeze® is the coolest-sleeping Tempur-Pedic we carry. Tempur-Pedic measure it as feeling up to 10° cooler than the TEMPUR-ProAdapt® across an eight-hour night, using their most advanced Pure Cool® Plus material under cool-to-the-touch covers. Thirteen inches tall.
Soft and firm are all-foam; the medium is a hybrid on 1,300 double-stacked springs. The step below is TEMPUR-ProBreeze®, and the same height without the cooling layers is TEMPUR-LuxeAdapt®.
Every one of these is on the floor in Richmond, Katy or Rosenberg, TX, so you can lie on it before you decide.
