Summary

Saatva

Comfort

"A comfortable mattress ensures a deep sleep. Saatva, REM-Fit Sleep 400 and 4Sleep 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 REM-Fit Sleep 400 or 4Sleep. "

REM-Fit Sleep 400

Support

"REM-Fit Sleep 400 and 4Sleep 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 Saatva better as its plush structure fits perfectly to the body curves and provides adequate pain relief to pressure points."

REM-Fit Sleep 400

Motion transfer/isolation

"For couples and pet owners, this is an important consideration. Saatva is bouncier than REM-Fit Sleep 400 and 4Sleep. Thus, it may cause issues if you or your partner move a lot at night. On the other hand, REM-Fit Sleep 400 and 4Sleep have excellent motion isolation properties because of the remarkable technology utilized in the layers. "

The Bottom Line

Conclusively, REM-Fit Sleep 400 is a great mattress offering exceptional 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.
