The edges of foam lack density (this means there's just not a lot of foam), so they're susceptible to cosmetic issues. One such issue is the foam being wrinkled, a cosmetic issue that can sometimes be visible through the covers. This issue does not impact the foams performance and is not abnormal.To deal with this issue, please do the following:1. Take the covers and liners off.2. Take a hair dryer and put it on the lowest setting.3. With the hair dryer a few inches away from the foam, go around all the edges to get out all the crinkles!When doing this, please be careful and keep the hair dryer a reasonable distance. It will take time, so do not speed the process up with a hotter setting, as this may permanently damage the foam. Below is a before and after example from one of our very own Roopers, Carlene. After:
