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

Big Fig

Comfort

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

Big Fig

Support

"Big Fig 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.

Casper
