TEMPUR-ProAdapt® is the middle of the Adapt family and the widest choice of feel in it: soft, medium and firm in all-foam, plus a medium hybrid, all 12 inches tall. It adds ventilated Advanced Relief® Material and a SmartClimate® cover that draws heat away from the surface.
It is the tier most people settle on once they have felt all three. If you sleep hot, compare it against TEMPUR-ProBreeze®; for more contour again, TEMPUR-LuxeAdapt®. The entry point is TEMPUR-Adapt®.
Every one of these is on the floor in Richmond, Katy or Rosenberg, TX, so you can lie on it before you decide.
