The 5 & 10 Year Mattress Warranty begins at the time the mattress is purchased by you, when the mattress is used normally for its intended purposes and on a rigid, solid surface or slatted bed base that is structurally capable of supporting the weight of the mattress and user(s). A proper bed frame is defined, for the purpose of this Mattress Warranty, as having at least five to six (5-6) leg support for a Queen, King, and California King Mattress, four (4) leg support for Twin and Full Mattresses. For Queen, King, and California King slatted style bed frames, there cannot be greater than five (5) inches between each slat in order to provide ample structural support for the foundation and user(s). Each slat needs to be a minimum of two and a half (2.5) inches wide. It is recommended that users rotate their mattress head-to-toe, 4 to 6 times in the first six months, then every 4 to 6 months for the life of the mattress, to ensure even wear. Failure to do so may void the Mattress Warranty. In the event of the issuance of a replacement mattress, Engineered Sleep Mattress Company may ask you to donate the used mattress to charity to help repurpose the mattress for someone in need. In that case, you will be required to provide a written receipt or proof of return, disposal or donation of the original, defective mattress, from a legitimate organization, before any replacement mattress or refunds will be issued. This Mattress Warranty is not transferable and applies only to a mattress purchased from Engineered Sleep Mattress Company by the original purchaser. DEFECTS COVERED UNDER THE MATTRESS WARRANTY: Any VISIBLE indentation equal or greater than (see chart) that is NOT associated with or resulting from a faulty, improper or unsupportive foundation, box spring or platform that is not designed or constructed so that it is capable of handling the combined weight of the foundation and its intended users. The indentation must be visible to the naked eye when no weight is applied to the top of the mattress. If the purchaser uses an inappropriate foundation, box spring or base as determined by Engineered Sleep Mattress Company, the Mattress Warranty, without limitation, will be void. Engineered Sleep Mattress Company may require the purchaser to provide proof of the quality of the foundation, box spring or base used. Any physical flaw in the foam that causes it to split or crack under conditions of normal use and proper handling. Any manufacturing defect in the mattress cover such as the fabric tearing or stitching unraveling. Any cosmetic damages to the mattress, NOT caused by normal wear and tear or that affect the performance of the mattress. THIS MATTRESS WARRANTY DOES NOT COVER: Normal wear and tear or any condition resulting from misuse or abuse of the mattress or failure to keep the mattress clean and free of stains and potentially unsanitary conditions. A normal increase in softness due to normal usage. Comfort preference. Any comfort level description of any mattress is solely provided as a guideline and Engineered Sleep Mattress Company does not guarantee the firmness or softness quality of any mattress, nor does it warrant that a particular comfort preference will be to your liking. Mold, odors, and/or discoloration caused by abnormal care including, but not limited to liquid spills, improper ventilation including, but not limited to humid climates and/or areas where the mattress is exposed to excessive water or humidity. Damage associated with an improper bed frame, foundation, box spring, or base as determined by Engineered Sleep Mattress Company. Imperfections that do not prevent ordinary use and enjoyment of the mattress by a reasonable person are not considered to be defects. For example, surfaces may not be perfectly even, and corners may not be perfectly shaped or symmetrical. These are not defects for which you can seek a remedy under this Mattress Warranty. More specifically, this Mattress Warranty excludes: (a) minor imperfections and slight cosmetic flaws; (b) normal wear and tear; (c) tears, stains, soiling, burns, and discoloration that occur over time; (d) dampness or mold; (e) individual or personalized preferences relating to firmness, texture, comfort, etc.; (f) normal body impressions not greater than one (1) inch in the mattress as measured below the quilt level — in other words, some settling of the fiber in the quilt should be expected and is not considered a defect); (g) individual or personalized allergies and sensitivities; and (h) naturally occurring cotton or latex foam aromas. In addition, this Mattress Warranty does not cover conditions resulting from abusive handling, misuse, or neglect. Accordingly, the following circumstances, if discovered upon inspection, will void your Warranty: (a) any unsanitary condition; (b) burns; (c) use of the Product on an improper bed frame; (d) physically abusing the Mattress; (e) attempting to clean the Mattress in an inappropriate manner; and (f) improper storage of the Mattress (including storage in damp locations, areas infested with insects or rodents, or any other unprotected storage areas); and (g) purchase from resellers who are not authorized retailers. YEARS 1-5 or 1-10: FULL COVERAGE During the first five (5) or ten (10) years of the Mattress Warranty, Engineered Sleep Mattress Company will not charge purchaser to repair or replace purchaser’s mattress if it qualifies under the Mattress Warranty. This period is non-prorated which means that Engineered Sleep Mattress Company does not charge a percentage of the repair costs or replacement product based on the amount of time you slept on the mattress prior to noticing a defect.
