Summary
Comfort
"A comfortable mattress ensures a deep sleep. Amerisleep AS3, REM-Fit Sleep 400 and Casper all are comfortable sleep surfaces. However, the choice depends on your sleeping position and comfort level preferences. For a plush feel, Amerisleep AS3 is an excellent choice while for a firmer feel, you may want to check out REM-Fit Sleep 400 or Casper. "
Support
"Amerisleep AS3 and REM-Fit Sleep 400 are more adaptable to people with heavyweight than the skinny people. The heavy layered structure is built to support people weighing over 200lbs. Lightweight people might like Casper better as its plush structure fits perfectly to the body curves and provides adequate pain relief to pressure points."
Motion transfer/isolation
"For couples and pet owners, this is an important consideration. Casper is bouncier than Amerisleep AS3 and REM-Fit Sleep 400. Thus, it may cause issues if you or your partner move a lot at night. On the other hand, Amerisleep AS3 and REM-Fit Sleep 400 have excellent motion isolation properties because of the remarkable technology utilized in the layers. "
The Bottom Line
Conclusively, Amerisleep AS3 is a great mattress offering exceptional comfort, support and motion transfer/isolation at a low price. Depending on your sleeping habits and preferences, all three mattresses are designed to rejuvenate your mornings through relaxing nights.
