This product is listed as being 18"x18". I ordered these pillows in 3 colors and was surprised when they all shipped in one small box. When I unpacked them they looked rather small, so I measured them and the dimensions are actually only 16"x16" and therefore a bit small for the the purpose they're intended. The filling/insert is not very plush and could use a lot more thickness. Otherwise, the pillows are very pretty and seem well made. My only disappointment is the inaccurate size and lack of enough filling.
