I love the idea for grownup....I'm just thinking it would turn out like the lovesaq pillowsaq I bought the kids for the playroom.
it makes a fullsized bed for guests when unzipped from its cover, has a rocking metal frame, and can be used in a variety of bean-bag like postions.
they consider it a wrestling pit, or roll down from top to bottom to the point where I'm worried someone is going to lose a tooth or get a broken nose and I have to chase after them with a tazer (jk!)
my parents had 2 loveseats they got free that had 2 back cushions each, two side/roll cushions, plus the two in the seat area. so a total of 12 removeable cushions. EVERY STINKING DAY after school i had to go re-fluff them back to their original shape and put them back. often several times per day, esp if it was a day off school.
I vowed no couch of mine would EVER have removable cushions. LOL.
....course, I grew up in a big family and opt simplicity over looks....my kids have plain fitted sheets for their bunkbeds and a no sew fleece blanket for covers. less to wash when they were PTing, and less to deal with for making beds. my older one esp sleeps all crazy like so making the bed would be a futile and exausting effort!
