I ended up ordering a travel hammock due to the size constraints of my exsisting posts. It came in only a few days! Here is the before:
and the after! I tried it out after mowing, but had dirty feet and didn't read the instructions on how to get in the thing, so I didn't spend much time and it wasn't very comfortable because I didn't know what I was doing!! I'll have to go back out later this afternoon and give it another whirl.
