As Mark asked did they come like this in shipment, or over time did this problem arrise. I can understand the seam bustin as Brent mentioned, BUT, bubbling under the vinyl sound like a problem with the adhesive process to the mdf, possibly a manufacturing problem, which is not out of the questions. jm2c
