Summary

Comfort
"Amerisleep AS2 has the softest sleep surface in comparison to OSO, Casper and Nectar. The use of high-quality plush layers offer contouring support to your body for a comfy rest. For a firmer comfort level, consider Amerisleep AS2."

Motion transfer/isolation
"The motion isolation offered by Amerisleep AS2 is much better than OSO, Casper and Nectar. The pressure absorbing layers prevent motion transfer, making UUUU favorable for couples, families with children, and pet owners. It is a superb choice for a peaceful snooze. "
