COCOON offers a LIFETIME warranty on all gear. Warranty requests are considered for defects in product manufacturing.  COCOON does not warranty products against normal wear and tear, unauthorized modifications or alterations, improper use, improper maintenance, misuse or neglect, or if the product is used for a purpose for which it is not intended.  If the product is beyond its practical lifetime and a product is no longer being produced, it is challenging to replace the product.  We try hard to repair products or offer replacement parts at a minimal cost or no charge when we can. 

A COCOON discount will only be offered if the product is no longer available. Except as expressly set forth in these terms and conditions, COCOON is not liable for any direct, indirect or consequential damages arising out of or resulting from the use of a COCOON product.  Processing of repair claims can take between 2 and 6 weeks depending on the time of year.  Warrantied products will be replaced or repaired at COCOON’S discretion. 

AirCore Pillow Bladder Replacement

As a small business, we value our customers and want to ensure that you are satisfied with your purchase.   You can send in your pillow for evaluation or we can provide you a link to our replacement bladder ($10.00).

Our first generation of pillows does not allow us to remove the bladder without cutting the seam on the cover.  We do have a replacement bladder that will fit the first generation pillows if you are capable of cut/sewing the cover.
