What style of your rug?

You'll want to select the rug first and then select pillows that work with both the sofa and the rug.

This rug is a great buy if you like the concept.

There are so many possibilities; it’s hard to give specific suggestions without seeing the house, knowing the styles you like, etc. Just for fun, I went to PB and found a few things I think look good (and calm) with such a wonderfully vivid sofa.

I am mostly traditional but I also like modern. I dont have a rug chosen, which can make it harder with all the options! I do like the lighter colors you picked for the pillows and curtains.

You've got a dark red couch, dark floors and a dark entertainment unit. I'd try a light rug with some red in it to pick up the sofa color. Light pillows and drapes.
