How have improvements in home insulation changed the requirements for modern bedding?
Answer
There is less need for bedding to act as a heat-retaining tent
In previous centuries, houses were drafty and lacked thermal efficiency, meaning beds were designed to create a micro-climate of warmth, often utilizing curtains to trap heat. As modern homes became significantly better insulated, the thermal requirements of the sleeper changed. Contemporary mattress manufacturers now focus on incorporating breathable fabrics and cooling technologies, as the bed structure itself is no longer required to serve as a heat-retaining enclosure.
