I love the texture and color that these add to my kitchen/family room.  My cabinets are dark brown, so these go really well, without being one-dimensional dark brown.  They are also surprisingly comfortable (although, when I'm wearing shorts I have to put a tea towel under my legs so that they don't get indentations from the seagrass.  

Pros: Comfortable, add visual interest to the decor.
Cons: Make indentations in my legs when I'm wearing shorts.
