I purchased a sofa from Coleman 4 years ago and within 2 years a spring had begun to peek through the bottom but didn't bother us until recently. I wanted to file a warranty claim (5-year manufacturer warranty for springs) and was told to take a photo of the sticker on the inside of the sofa with the serial number. Well, the tag with the number had worn and was not legible. So because of that, they said I cannot file a warranty claim even though I have the email showing I purchased the sofa with them 4 years ago.
