I couldn't help but notice that your furniture is angular, modern and monochromatic except for that bright blue chair.. I think it would make it more difficult to choose a rug with that piece in place, and the style seems to fight with the rest of the furniture. I also like aktillery's choice of rug best.

You have beautiful hardwood floors. I don't think you need a rug where you have the gray one currently. Look for one larger, multicolor rug for the seating area that combines the warmth of your floors and the grey of the furniture. Maybe even with a bit of the blue from your room above the steps.

Wow!! Thank you Beverly!! That’s awesome what you did with placing picture on the wall, placing the rug on the floor, and placing it in different areas. We are a bit stuck on the location of our couch and rug, as we use a wheel chair (has to be open), but based on your pictures, i think we could go up to a 10 x 14 rug size instead of the current 9 x 12 (currently pushed back to the wall). I just have to make sure there is enough room to “roll” on the floor (without the rug getting in the way). I love the colors you posted, as well as the inspirational/idea photos!! I definitely like and want one or more of the colors you posted. There is a rug currently on sale that is very similar to the one your posted (aqua and ivory). It’s a 10 x 14 for only $220 (says it’s normally $1200) with a matching runner for only $48. It’s a shag style, BUT....... I “think” I really prefer a wool rug.

I made this on a design tool for your room. It shows a rug on the medium to smaller size with the dark hardwoods and white tile you talked about. I think because you have hardwood it may be better not to cover them all up which would give for a better design with more textures in my opinion. Hope this helps!
