Checking is a term used to describe small cracks that appear on the end grain of the wood. These checking cracks would most likely occur at the ends of the slats, ends of the arms or anywhere where end grain is exposed. This is completely natural and not a cause for concern. These checking cracks will stabilize in the first few weeks of exposure.
Wonderful experience dealing with Golden Teak! Everyone I spoke to was very helpful, and the furniture is beautiful! I bet I couldn't find anything as nice here in the NY City environs for less than twice the cost. Keep up the great work! D.F.
