Yep, she's a keeper.
...so, what *are* you using?
That's a papasan chair cushion, covered with a fitted sheet. The excess is tucked under the cushion.
Remember, I told the story about buying a papasan chair on Craig's list (to take to the house at the lake).
Chair, cushion & footstool frame (no cushion) for $30.00 found on Craig's List.
vs.
Frame (only) World Market $69.99.
Cushion (only) World Market $69.99 - $79.99.
Papasan Stool Frame World Market - $29.99. Can't remember how much the cushion for that was. I think around $25 - $30.
I really only wanted the frame, the guy grossed me out though, so I was never going to use the cushion,

but hating to waste it, I decided to use it for Rita on the floor.
It didn't smell or anything, and it actually looked brand new, but still *shudder*, couldn't do it.
I sprayed it down with Lysol spray, set it in the sun for like three days (the sun kills germs too).
...extra large dog beds from Orvis were a bit over $100.
Um yeah, that's the extra large. 48" diameter
