Support is important in a mattress. A mattress that is too firm might be supportive, but not as comfortable. Meanwhile, a softer mattress might leave you feeling sore when waking up. The Tempur-Contour Supreme Firm Mattress is made for folks who prefer firmness over cushiness, but it's firm and supportive while still feeling plush. This 11.5-inch thick foam mattress features patented Tempur material that provides full-body support for all sleeping positions, regardless of height or body shape. This mattress also features the SmartClimate system that draws away moisture to keep sleepers cool and refreshed. All of this rests upon a sturdy, supportive base layer that further disperses heat to keep sleepers feeling good.
