Summary

Casper

Cost based value

"Although all these three mattresses are offered within the same price range, each of these sleep surfaces has a different value for money. Depending on your usage and the availability of the features, each of the mattress performs uniquely. Amerisleep AS4 and Amerisleep AS3 provide regular features for an affordable price while Casper is slightly luxurious."

Amerisleep AS3

Comfort

"A comfortable mattress ensures a deep sleep. Amerisleep AS3, Casper and Amerisleep AS4 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 Casper or Amerisleep AS4. "

Casper

Support

"Casper and Amerisleep AS3 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 Amerisleep AS4 better as its plush structure fits perfectly to the body curves and provides adequate pain relief to pressure points."

The Bottom Line

Conclusively, Casper is a great mattress offering exceptional support and Cost based value at a low price. In terms of comfort Amerisleep AS3 excels the other two mattresses. Depending on your sleeping habits and preferences, all three mattresses are designed to rejuvenate your mornings through relaxing nights.
