The Swacchao! series are sitting Nendoroids. They are sold as a whole Nendoroid or as only a lower half with a chair. All Swacchao chairs use the same sculpt and paint job and come with a peg to secure the Nendoroid to the chair and double-sided stickers to affix the chair to places like bookshelf ledges. See last photo for instructions on how to assemble the chair for use on a ledge.
