Vintage kilim living room set

That is a striking living room setup! The bold, red patterned vinyl rage kilim upholstery has a fantastic, warm bohemian or global-inspired energy.
Because the sofa and ottomans have such a strong, repetitive pattern and intense color, decorating around them is all about balance. You want to create a space that feels intentional and cohesive, rather than chaotic.
Here are a few design ideas to help you style the rest of the room:

 Balance with Neutral Walls
Since the furniture is the undisputed star of the show, keep the walls relatively calm.
Warm Off-Whites or Creams: This will keep the room feeling bright and airy while complementing the warm tones in the fabric.

To break up the massive block of red pattern on the sectional, introduce solid-colored textiles with plenty of tactile texture.
Throw Blankets: Drape a chunky cream knit, a fringed beige linen, or a deep olive green faux-throw over the chaise or back cushions.

Solid Pillows: Introduce a few solid-colored pillows in materials like velvet, washed linen, or leather to give the eyes a place to rest.

Ground the Space with the Right Rug
The cream rug in the image works well because it creates contrast. 
Kilims : A thick, woven kilim rug would add incredible texture and enhance that global, bohemian aesthetic.
Subtle Vintage/Distressed: A highly distressed rug with faded, muted tones that hint at blues or sage greens can look incredibly sophisticated against the crisp pattern of the sofa
Art: Look for artwork that incorporates small accents of the sofa's red or orange tones, but relies heavily on neutral backgrounds or negative space so it doesn't compete with the furniture.
