The Apogee Mattress warranty covers purchases from authorized dealers, requiring a warranty card, receipt, and the mattress for claims, excluding stains, fabric tears, and stitch openings reported after 15 days. Claims can be made by returning the mattress to the place of purchase or using the "Service @ Your Doorstep" for a fee, with replacements depending on availability or a similar model if discontinued. The warranty excludes damage from improper use, infestations, natural calamities, and certain structural issues, with specific exclusions for comfort preferences, minor depressions, odors, and liquid spills.
