When your home has a fairly open layout, it helps to distinguish one space from another with different colors or patterns. By using mainly neutrals in the living and kitchen areas, this home's orange dining area with modern floral rug feels separate and distinct.
An orange floral rug under Chinese orange chairs sets the dining area apart from the rest of the open floor plan, and it's just plain fun. The Kaley Sculpted rug is no longer available from Pottery Barn, but it sometimes shows up on eBay.
Like the arrangement, mismatched chairs and table. Love the orange but almost too much even for me, and looks to "Halloween-ish" with the dark cabinets. But overall design and use of space is very nice.
