Niki Papadopoulos These cute little puffs are from CB2! If you click the "more info" button under the image, it will take you to the product link. Good Luck!
Consider adding a pouf. More than just a fun accessory, a pouf of the appropriate size can be tucked beneath your desk to use as a footrest. When not needed, you can pull it out and use it as a mini side table for stacks of books and magazines.
In case you hadn't noticed, poufs have taken over for bean bags. While you can't sink into them, they have a more uniform look, and, I don't know, if you do sit on them, you'll probably build up some killer thigh muscles in some sort of pilates kind of way. Regardless, they look good and add texture to your room.
