For instance, I had to take both arm pieces off, almost completely. Why? Because the seat couldn't be stapled to the frame while they were attached. So, while they were off, I reinforced some areas with more foam and bonded poly - it just seemed a little thin to me.
So, for future reference: put the seat piece on FIRST! It will save you a lot of grief (and rework). Wow, I hate rework!
Now, I have to take the front band off and re-do it because there are 2 (yes, count them - 2!) staples that can be seen one above the black welting and one below. *sniff*
In other news - the inside back is stapled down. That was pretty painless. For this project, I used 3/8" staples and we should buy stock, because I used a TON of them.
