When somebody sits on something or lays on something they would be testing the comfort, so comfy testers are people who go round
trying to find what is comfiest.
They would compare answers with one another to hear each others opinions
on the level of comfyness.
Things that aren't comfy such as a thorn bush would get about a 1 out of 10 but things such as
memory foam mattress would get roughly a 9, 10 if extreme comfort is found.
