LinenSpa products are backed by extensive warranties and they have some of the best customer support in the industry – which is always a mark of a trustworthy manufacturer. Even though your LinenSpa mattress protector is taking care of your mattress, it too needs to be taken care of. Be sure to wash the protector regularly in cold water with a gentle detergent. Do not put in the dryer or take to the dry cleaner. If you take care of the product it should last past the warranty which is an extremely generous 15 years.
