Warranty Information

At Caluful Mattress, we are committed to providing the highest quality products that have gone through extensive testing and inspection in order to ensure that you receive a healthful night’s sleep. Diamond’s commitment to quality and comfort has led us to offer industry leading warranties on all mattresses and foundations.

●How to Make a Claim  
Adjustment Period: As with a new pair of shoes, after so many uncomfortable years on your old bed, it may take time for your body to get accustomed to your new gel memory foam mattress. This period of adjustment varies, from as brief as one week, but normally takes 2 to 4 weeks to get fully used to your new mattress as your muscles and joints recondition themselves.  
Body Impressions: The comfort layers of a mattress naturally conforms to your body and often results in impressions. These body impressions are normal and therefore do not mean the mattress is defective.  

*To prevent excess body impressions you must rotate your mattress – whether it is “one-sided” or “two-sided."  

body impression

A “body impression” occurs when the comfort layers of a mattress naturally settle and conform to an individuals unique body.


“Sagging” is often caused by an improper foundation or frame.

A stable, supportive frame is necessary in the prevention of sagging. To comply with the warranty queen and king size mattresses must be on a frame that has solid center support. The queen must have at least one center leg, and the king must have at least two legs to ensure proper bed support. Make sure that all legs are level.
