Newsflash: Innersprings do this 28% better


Foam beds are hot and innersprings sleep cooler.

As Ron Burgundy would say, “It’s science.”

Leggett & Platt partnered with the Kansas State University Institute for Environmental Research, where it was shown that innersprings transfer heat up to 28% more efficiently than all foam products. More heat transfer leads to a cooler core. All that adds up to cooler sleep. As the anchorman might say, innersprings are “Kind of a big deal.” 

Face it, gimmicks and applications might create an initial cooling effect, but over time most of those add-ons eventually heat up and the warmth does not dissipate until the heat source (e.g., a person’s body) is removed.

Not unlike Ron Burgundy trapped in a glass case of emotion, body heat gets trapped in a foam case of hotness. Innerspring and fabric-encased coils sleep cooler than all-foam mattresses because innersprings feature an open design, while foam is a lock-cell material that traps heat.

Innersprings are proven to more efficiently move heat away from a sleeper. Like we said, “It’s science.”
