No, it does not.
The Nolah foam mattress is not temperature sensitive, so it sleeps cool and does not trap heat as traditional Memory Foam does.
Any form of Memory Foam is viscoelastic, meaning that the foam contains a chemical that reacts to body heat. This is what makes up the main property of Memory Foam, but also the main issue, that it trap in body heat to sleep hot and uncomfortable.
The Nolah Air Foam™ is temperature neutral as it does not contain the viscoelastic chemical and therefore sleeps cooler than any Memory Foam mattress with or without cooling gel!
