Throw pillows have different shapes, styles and sizes. If you very keen on the materials of their coat, you can get the piece of your preference. When you go to shop a throw pillow for your home, the shape that you see in common is square and has the size of 16 to 18 inches in size. You can also see other shapes if you prefer a different type. Before you buy for your throw pillow, be sure that you are certain on how it will be used. If you will need a full support on your back while leaning on your sofa, the square shaped throw pillows are the best in providing full-back support while the rectangular shape throw pillows are best in supporting the lower back portion of your body on your nape for proper neck support too.
The size of your throw pillows should compliment on the size of your sofa set. If the sofa is big enough, you can place bigger size decorative throw pillows on your couches. Bolster serves different purpose than the throw pillows. If you have bought a couch in spare, you can put round pillows on top of it to soften the look of your furniture. You can try to mix the shapes of your throw pillows if you are not certain on one shape. You can also make a customize suit and uniformed looks for your throw pillows in case you will need to clean its coat if it gets dirty.
