Apparently, this was a very old model. The owner says it the previous owners reinforced the leather straps with nylon (aftermarket) so ignore the green.
What I've been wondering is, when did Knoll start stamping the bottom of their daybeds with Knoll all over, like in this picture
I know that the older models didnt have stamps or the knoll logo on them, so that makes it harder to authenticate an old model like this... so my other important question is
...does quality leather ever bleed into the fabric on the bottom?? that seems to be weird.
Here are the pictures
