For those of you like me, here's a recap of how I did it. It was super easy (don't know why I was intimidated) and it took about 10 minutes from start to finish.
You need a way to get the old fabric off. I had tiny nails holding the fabric onto the base, so I used a hammer.
Hubby let me use his staple gun to attach my new fabric.
I laid the base face down on the fabric.
Then I stretched it smooth and attached it with staples all the way around.
Any excess in the back was trimmed off.
And here's my newly upholstered chair:
I am wanting to repaint the chair in the near future, but it already looks a million times better!
Super Simple...Super Cheap...Big Difference!
