Air flow mattress constructions and variable density mattress cores

摘要

The present disclosure and related inventions includes various mattress constructions with improved air flow characteristics, and in particular mattress constructions which induce or control air flow when force is applied to the mattress support surface.

主权项

1. An air flow mattress comprising:
a mattress core; a mattress topper located at the uppermost planar surface of the mattress, the mattress topper comprising one or more layers of foam; a plurality of air flow passages in the form of elongate tubes located between the mattress core and the mattress topper, each air flow passage having at least one intake and an exhaust, the exhaust having a valve which operates as a one-way valve to allow air to escape the air flow passage.
