Choosing the right size of cushion for accent chair can be hard Armchair is not just chair, it works as style accent. Throw pillow adds comfort and improves the shape and size of the chair. Proportion decides everything when talking about sizes of cushions.
For normal armchair or accent chair, choose smaller 20-inch lumbar cushion or square of 20 to 22 inches. 20×14-inch rectangular pillow works well for accent chairs and small sofas. There is no “standard” size for decor cushions that improve the look, but some sizes work best in certain cases.
How to Choose the Right Cushion Size for an Accent Chair
When you choose square cushions, think about the width and depth of the accent chair. Size equal to or a bit bigger than the seat width gives the room full and welcoming look. Even so keep you from overfilling the chair with too many square cushions.
For instance, chair wide in 22 inches works well with cushion between 18 and 26 inches wide.
The thumb-rules are these: 30-inch padded cushions work well for accent chairs over around 27 inches, and 46 inches or more for big chairs. The best size genuinely depends on the chair itself, especially on its depht.
For arranging cushions on armchair, a 20×20-inch cover with 22×22-inch insert in the back part and 12×20-inch cover with 12×22-inch insert in the front works well. Lumbar cushions also go well with chairs. Throw covering over small lumbar or back cushion can match the sofa arm for nice rest.
Color has big role. Choose cushions in colors opposite to that of the chair for bold and elegant look. For instance, orange cover-covers strongly contrast with blue sofa.
For luxury look, add dimension by using same-color cushions with different shade, as lemon green cushions on forest green sofa. The color of the cushion should agree with the main accent in the room.
Right pillows can tie the room style and add fancy touch to the space without long commitment. Because covers commonly sell separate from insert, you easily buy new to update the style any time. Decor cushions offer fast and cheap way to refresh the home.
Mixing forms and textures keeps everything interesting, for instance match patterned cushion with cable knit bolster for look that matches but not too much.
Adding cushions or throws to chair improve comfort. Pillow behind the back gives extra support. If the seat back cushion is flat and feels lacking, simply use throw cushions to fix that.
