Numero Teak USA has one year warranty against defect in workmanship and materials on all of its furniture.  The warranty applies to the original owner and does not cover damages caused by the effect of normal wear and tear, severe weather occurences, negligence, misuse and/or unauthorized repairs.  The owner is responsible for routine cleaning and maintenance.  

All wood, including teak, may develop fine cracks or "checking".  This is caused by the wood expanding and contracting due to changes in the weather and the resultant change in the wood's moisture content.  The "checking", if it occurs, is normal and will not affect the life or serviceability of your furniture.
