During the first year in the unlikely event of your mattress defect, Springfit Mattress #world collection warranties free replacement from the date of purchase against any material workmanship defects. Thenceforth the warranty benefits will be given on pro-rata basis.For example product with 5 years warranty, if defect appears after 3 years of use, pro-rata money back warranty is applicable for balance 2 years. It means that the Pro-rata value available to a customer on that say mattress worth 10000 with warranty of 5 years would be 10000 x 2/5 = 4000. So on replacement of old mattress under warranty claim of current worth 10000 you will pay 10000 - 4000 = 6000. *Pro-rata will be calculated on the prevailing price at the time of warranty claim
