Summary

Saatva

Comfort

"A comfortable mattress ensures a deep sleep. Saatva, Amerisleep AS4 and Casper Wave all are comfortable sleep surfaces. However, the choice depends on your sleeping position and comfort level preferences. For a plush feel, Saatva is an excellent choice while for a firmer feel, you may want to check out Amerisleep AS4 or Casper Wave. "

Saatva

Support

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

The Bottom Line

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