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 Purple provide regular features for an affordable price while Casper is slightly luxurious."

Purple

Comfort

"A comfortable mattress ensures a deep sleep. Purple, 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, Purple is an excellent choice while for a firmer feel, you may want to check out Casper or Amerisleep AS4. "

Purple

Support

"Purple and Casper 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."

Purple

Temperature regulation

"Purple is made up of materials that retain heat during the night. If you tend to sweat while you slumber, you may want to go for Casper or Amerisleep AS4 as they contain proper temperature regulation mechanism. These two mattresses offer a chill surface for a refreshing sleep. "

The Bottom Line

Conclusively, Purple is a great mattress offering exceptional comfort, support and temperature regulation at a low price. Depending on your sleeping habits and preferences, all three mattresses are designed to rejuvenate your mornings through relaxing nights.
