Understanding the importance of motion isolation in a mattress can greatly contribute to a more restful sleep experience.

To improve edge support on the AS3 mattress, customers can consider using a solid and supportive bed frame or platform. Also, rotating the mattress regularly can help distribute weight evenly and maintain consistent edge support.

It is important to note that the levels of VOCs released during off-gassing are typically low and dissipate over time. Also, mattress manufacturers have taken steps to minimize off-gassing by using low VOC materials and implementing production processes that reduce emissions.
