We had a similar trim issue under the TV. It seems many dealers remove the TVs during setup as they are an easy target for thieves, who can abscond with them in about 90 seconds. Sometimes the crew are careless and damage the trim. PrimeTime replaced our damaged trim without question.
A Memory Foam topper will fix your bed issues. We have a 4" foam that is terrific!
