Can You Replace the Top of Your Sleep Number Mattress?

Select Comfort, manufacturer of the Sleep Number Adjustable Bed, offers a product replacement service to customers who provide proof of purchase. Many of the bed's parts can be ordered online through the company's website. The only exception is for the top of the mattress, or mattress cover. This part can only be ordered by phone through Select Comfort's customer service department.

About the Sleep Number Bed

The Sleep Number Bed, which is an air mattress entombed in layers of anti-microbial foam and padding, is constructed like a puzzle. Each bed component, if damaged or worn, can be replaced or purchased through the company. If the damaged part or mattress pad is not covered under the company's limited warranty, a replacement can be purchased. The cost of part is determined by the part itself, the type of malfunction and the age of the bed.

Ordering the Mattress Cover

Because mattress covers are customized to bed size and model number, the price for a replacement varies. Select Comfort recommends that you contact Customer Service for a price quote for a mattress cover. While many replacement parts can be ordered online through the company's website, the mattress cover cannot. Be prepared to provide proof of purchase, and to describe how the part was damaged. The toll-free number is listed on their website (

Warranty Coverage

According to Select Comfort's limited warranty, the Sleep Number bed is guaranteed against defects in materials and workmanship for 20 years from the original purchase date. For the first 2 years, defective parts are covered at no cost to you. From 2 to 20 years, the percentage you pay is 20 percent plus 4 percent of the price for each year from the original purchase date. If the company determines the part is damaged due to tampering or misuse of the product or from laundering practices, the part won't be covered under warranty.

Mattress Covers and Mold

According to Select Comfort, all bed components are treated with an antimicrobial substance to resist mold and mildew. If, however, the mattress cover is damaged by mold, the company will do what they can to rectify the situation. According to the website, Select Comfort will "stand by their product and will replace any and all parts to make the bed like new." If your Sleep Number mattress cover was manufactured prior to 2002, check with Customer Service about the warranty concerning mold. Antimicrobial mold treatment was reformulated after 2002 and older beds may not be covered.
