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.
I have 6 of these for my outdoor kitchen. I finished them this weekend and they look fantastic! They were easy to assemble. The price/quality can't be beat.
10/26/2015 - I don't do social media but I would like to provide a review. The tables were very good quality (I used to work for Gloster Furniture so know quality teak) and I was very happy with them. I would order them again and advise others as well. I did take a picture of it actually, but not sure you can use it as it shows my other teak around it, image attached. PD, DC. (Teak End Table 067) See Customer Photo Here
