The tiny cracking in plywooden product is inevitable

It is not 100%, but there would be tiny cracks in plywood products.

Jose's case is the example.
To make the plywood curve, we will need to make the wood panel soft by using the steaming technology. Once the shape is finalized, then cool the curved plywood and dry it.
Thus, if the chairs or furniture are placed on a hot and humid environment, the surface would deform and the tiny cracks would show.
But this is only for the surface, the inside instruction is still strong and stable, those tiny cracks would NOT affect the usage at all.

Even though, we still agreed to offer Jose a new chair at a reduced cost, to ease his anxiety.

Yes, sometimes, you are not only needed to be a professional manufacturer, you have to be a psychological volunteer too.
