Using these pillows is super easy. You can place them on your favorite chair, sofa, or bed to instantly add a touch of style. For the best back support, use the lumbar pillow when sitting. When it comes to maintenance, if the pillow gets dirty, you can gently spot - clean the pillow cover with a mild detergent and a soft cloth. Since no assembly is required, you can start using them right out of the box.
