Hi fireman43,
We have a couple of documents in the manuals section of the forum that speak to counter top care.
Here's a link. Some owners have repaired deep scratches by sanding with progressively finer grit paper and then polishing with a very mild abrasive cream. It can be a little scary though because during the early stages, the counter tops may look like you've ruined them.
If your trailer is fairly new, it's possible you might be able to buy a new mattress bag from Heartland Parts. Call Heartland Customer Service at 877-262-8032 / 574-262-8030. Have your VIN # ready. If Heartland doesn't have the bag, ask for contact info for the furniture supplier.
