Repair or replacement as provided under this warranty is the exclusive remedy of the consumer. Kolcraft shall not be liable for any incidental or consequential damages for breach of any express or implied warranty on this product, except to the extent this exclusion is prohibited by applicable law. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

          Any implied warranty of merchantability or fitness for a particular purpose on this product is limited in duration to the duration of this warranty.

          What does the crib warranty cover?
          The manufacturer warrants that all structural elements of this crib, including hardware, joints, bolts and mechanical devices shall be free of any defects under normal household use and will be replaced or repaired free of charge for ONE YEAR from the date of purchase. You must be the original owner of the crib and must properly use and care for the product as indicated in Section 2 below.

          Proper Crib Care and Maintenance
          After completing assembly, check that all bolts and screws are secure and tight. Hardware can become loose over time, so it is your responsibility to periodically check the tightness of all fasteners as long as you use the crib. Wood is a natural material and as such, it can be affected by changes in temperature and humidity. Extreme changes in humidity and temperature can cause the wood to warp, swell, crack or shrink, thus compromising the structural integrity of the crib and making it dangerous to use. Cribs should always be stored indoors in climate controlled, dry locations. Use care when using a vaporizer or humidifier around the crib. Do not aim the vapor at the crib or any other wooden furniture in the nursery. Avoid using vaporizers or humidifiers for extended periods of time.
          To clean the crib, wipe with a damp cloth and immediately dry the surface. Do not use any chemical cleaners or polishes. Such products can leave a residue on the finish and come in contact with your child. Your crib has a durable and protective non-toxic finish, however if you decide to refinish it, you must use a non-toxic finish specified for children’s products. Do not use any toxic stripping methods to remove the old finish.

          If you purchased your mattress from and have a warranty issue - call us at 1-800-506-5890

          If you purchased your mattress from another retail store, please call Kolcraft directly.
