I don't disagree. I have never sat in one that I wasn't wishing for something more comfortable within 10-15 minutes. Usually cushions are a memory foam that is way to soft and ends up being 1" thick for an average sized guy. I "Generously" offer to allow guests the dinette seats and bring in a camping chair to sit at the end of the table if we are stuck inside playing a board game or cards. Fine for kids or those hovering around 100 lbs but torturous for anyone approaching 200 or with a back or hip issue.
I bought a toy hauler with a happi-jack opposing couches/bunk setup and while it wasn't the reason I went toy hauler, it was a definite selling point in my mind.
