Using these lumbar pillows is a breeze. Just place them on your favorite chair, sofa, or bed. They're great for adding a pop of color and extra comfort. When you're lounging, you can lean back against them for support or hug them while cuddling. As for maintenance, spot - clean them with a mild detergent if they get dirty. Avoid machine - washing to keep the fabric and the geometric pattern in good condition. Also, keep them away from sharp objects to prevent any tears. These pillows don't need any assembly, so you can start using them right away as soon as you get them. Make sure to check the options you've selected to ensure you get the exact color, size, and other features you want.
