office chair fabric

Over break, I was hoping to get a chance to reupholster my nasty office chairs.  They're so ugly, I keep a black sheet over them because I just can't bear to look at them.  And as for that blue thing under the chair?  It's just a box, so try to ignore it. :)

I've been trying to find a suitable fabric for the chairs that goes with the yellow, gray, and white color scheme I have going on.  However, ever since we decided to change up the design of our master bedroom, I've been itching to possibly switch up the color scheme in the office to green and blue instead of yellow.  Because of my indecisiveness, I am struggling to find the perfect fabric.

Here are some of my top contenders right now...

...if I stay with a yellow color scheme:

1 // 2 // 3

...if I switch to blue & green:

1 // 2 // 3 // 4

...or if I stay neutral because I'm indecisive and want to keep my options open:

1 // 2 // 3 // 4

As of this very moment, I'm really liking the blue and green daffodil-esque fabric.  But then again, I saw that bird fabric on a chair this summer at Pier 1, and I really love that too.  

Decisions, decisions.  Which would you guys choose?
