Sleep Trial and Warranty

  • Trial Period and Guarantee

    Trial Period and Guarantee: Sealy mattresses are available through third-party retailers. For this reason, customers should defer to the sleep trial and return policy of the brick-and-mortar location where they purchase their mattress.

  • Warranty Details

    Warranty: Sealy offers a 10-year warranty for all mattresses.

    1. Warranty coverage begins on the date of original purchase. Two types of warranty coverage are available for Sealy memory foam mattresses:
      • Products with the 10/10 label will receive nonprorated coverage for the entire duration of the 10-year warranty. This means owners will not have to pay additional charges for replacing a defective mattress. However, they will be responsible for shipping and transportation fees; these fees will never exceed standard freight charges.
      • Products with the 5/10 label will receive nonprorated coverage for the five years. From years five to 10, owners will pay a prorated charge to replace their defective mattress. This charge is calculated by multiplying the original mattress price and the number of years the mattress has been owned, and then dividing that product by 10. For instance, a mattress priced at $600 that has been owned for seven years will result in a prorated charge of $420 during that entire coverage year.
    2. If a mattress has been discontinued, Sealy will use the most comparable mattress in their current line to calculate the prorated charge.
    3. Replacement mattresses will be protected under the same warranty as the original model. Owners who wish to upgrade will pay the difference in price between the original mattress and the upgrade model.
    4. Sealy mattresses are designed for use with certain types of foundational support. A queen- or king-size mattress must be supported with a bed frame that has a ‘rigid bridge bar with a supporting leg’ and at least five legs or at least five ‘equally spaced hardwood slats’. Sealy will void the warranty if the mattress is used with an inadequate support system, or if the mattress is found to be in unsanitary condition.
    5. Floor or demo models are not eligible for warranty coverage.
    6. The warranty will cover the following mattress defects:
      • Visible indentations or sagging in the mattress surface that measure three-quarters of an inch (3/4″) or deeper.
    7. The warranty will not cover the following:
      • Indentations or sagging that do not measure three-quarters of an inch (3/4″) or deeper. This is considered standard wear and tear.
      • Repair or replacement requests that occur due to changes in the owner’s comfort preferences.
      • Burns, cuts, tears, stains, and other types of physical damage that occur due to owner misuse, improper cleaning, and/or inadequate foundational support.
    8. Warranty coverage is exclusively extended to original owners who buy their mattress directly from Sealy or an authorized Sealy retailer. Those who buy or acquire their mattress from the original owner or an unauthorized Sealy retailer will do so ‘as is’, and will not qualify for warranty coverage. customers will be eligible for a three-year limited warranty offered through that website.
