White

Needs to be as neutral as possible after the statement those armchairs make. Rug looks like it'll play nicely with the armchairs and you can incorporate some of the rug's tones into your cushions/throws.

Definitely a neutral, whichever one you like the most. Since the chairs and rug are so bold, the sofa needs to take a backseat and let the statement pieces shine.

White, light gray, or natural linen color. Love the chairs!

A natural linen would contrast the other two nicely, but I LOVE the zebra idea. I think it would look great but still be neutral colors, but like bel... said, only if you are daring. Are the chairs velvet? It's hard to tell, since they look like they are glowing in the picture.

Your photo shows a greyish wood tone - I think a soft greyish fabric.

...unless you find a pillow like this with linen background, then linen. "Charcoal, Hot Pink, Poppy Red, Grass Green, Aqua Blue, and Pale Lime Green are artfully showcased against a warm Sand background."

I vote for Grey!

Your best choice would be an off white sofa that it very linear and simple.

If your lamp or frames or pouf tends to be silver, then probably same color as table is, so as not to over-complicate [with sand/linen].

Just for example, this combines grey and creamy --

But it depends what colors you'll pull out of the rug: any burnt orange, then I might not go grey..... etc...?

also if you use reclaimed or rustic wood a bit, maybe not grey couch.

Something neutral - maybe a dark beige? Since you're placing it on the carpet, there's no need to worry about picking a thick rug for underneath the sofa to protect the floor.

Ooooo navy is a good idea. Thinking outside the boring, neutral box.

With the white coffee table, I like the idea of choosing another lighter color from the rug that you love - a solid - and going with a sofa in that color. It's difficult to see the exact shades, but my eye is leaning toward the blue/aquas and that color will be much more forgiving than a really light color since I'm assuming you have friends who drink wine and are known to spill from time to time! Although zebra print is young and fun, I think it may get really old really quickly. Maybe some zebra pillows on those darling hot pink chairs if you love the zebra idea. Or on the sofa along with other bright and fun pillows. I think if you find a color you like then you will be happiest with a solid sofa in the long run. Have fun!

love your choices and congrats on your place. let me show you my favorite zebra
