Mattress Buying Tips! Check the warranty! A good mattress will have a minimum of a 10 year full replacement or non-prorated warranty. All latex mattresses from Unique Sleep have a 20 year limited warranty. We are committed to using the highest possible quality of materials available in each of our products. Mattresses can have their warranties voided due to the use of an improper foundation/ frame and the presence of staining, soiling or fluid penetration, so make sure to use a proper foundation and a washable mattress protector.
