Bolster pillows are cylindrical pillows that are commonly used on sofas and beds. As decorative throw pillows, they can add a beautiful finishing touch to sofas, chaise lounges or chairs. If you have a sofa with high arms, the bolster pillow can help soften the look by creating a step-down affect. They are also effective when used on slip covers to help create clean lines where the slip cover may naturally pucker or fold where the sofa arms and seat join. Smaller decorative bolsters can also be used as finishing pillows on beds. Place them in front of your larger toss pillows to add color and a contrasting shape. Depending on the size of the bolster pillows, they can be used for neck or low back support.
