Patterns on Furniture

We have these chairs from ikea:

I love the shape of the chair, but the color & pattern has been hard for me to work with in our living room. There's a website called Bemz which makes slip covers exclusively for Ikea furniture. I think I am going to tryout this color scheme:

in the living room or something close to it and I'm deciding on what color to do for the chairs. Would it be better to stick with a solid? What color? Have you heard of the 60-30-10 rule for using color in a room? I'm going to have to think about this, as in the past I have haphazardly bought furniture and items & didn't not like outcome!

But I love this pattern and color for the chairs....

I've always been of the opinion that it makes more sense to buy solid colored furniture and then decorate with patterned throw pillows to mix it up. That way you can change things when you get tired of it. But...I really like this pattern! Our last patterned-purchase did not end well, but I did not particularly love the leaves to begin with. So what do you think, solids only or are patterns okay for furniture?
