No, it wasn't an easy removal. I removed my upper bunk this spring. Previously I put in a wood clothes rod in the lower bunk, pole and fittings from Home Despot. I moved that up in the upper bunk area but had to add two wood spacers going from the rear wall to the over dinette cabinet, or I would have had to buy a new clothes rod dowel for adding 1/2". There are pics in the "What did you do to your Camper today" thread.
Once you pry off the top & bottom upper bunk panels, you have access to the screws holding the bunk frame to the walls, 10 or 12 of them. I had a couple that would not unscrew and had to cut between the frame and wall with a Sawsall. Thinking back, instead of trying to save the frame, I should have destroyed the sections of bunk frame to protect the wall finish and exposed the bad wall screws. I wanted to be able to reinstall the upper bunk for resale. Rebuilding it would have been simple enough.
Now the lower bunk can be used easily by an adult and be used as an out of way seated dressing area with no windows.
Both the master bed and lower bunk have Zinus brand foam mattresses and are very comfortable. I did not buy a second new bunk mattress, just previously stacked the two factory ones on the top bunk.
