Hey Heba,

You can do a few things to brighten up your space, but my favorite option would be with an area rug.

You could do something with a more earthly tone, but still have some color, like this rug that pulls some of the brown from your sofa, but also adds some green:

Brown Persian Rug, 7'9"x11'4" · More Info

Brown and Gray Flatweave Kilim Rug, Rectangle, 5.50'x7.92' · More Info

Hey Heba, I think it would be a great addition to the space and will brighten up the room!
