Cushions make the sofa comfortable to sit on and to sleep on. However, your sofa or chair will not be as attractive if you do not put cushion covers on your cushions.
Cushion covers do not just hide the flaws of your cushions but it makes your cushions more appealing. Cushion covers are great fashion items but looking at the same colour and pattern for months can make it look boring and ordinary. When you start having this kind of impression every time you look at your cushion covers then it is time to re-invent them.
