Using these pillows is a breeze. Just place them on your sofa, chair, or bed to instantly upgrade the look of your space. They're also great for providing lumbar support when you're sitting. As for care, it's simple. Spot - clean them with a mild detergent and a soft cloth when they get dirty. Avoid using harsh chemicals as they can damage the polyester fabric. Since no assembly is required, you can start using them right out of the box. Remember, these pillows are designed to hold their shape, but try not to over - stuff or squeeze them too hard to keep them looking their best. Also, choose the right color and size according to your personal taste and the existing decor of your room.
