Beach chairs are lightweight and portable, providing a comfortable place for you to recline while at the beach. Most beach chairs are inexpensive, but the sea air and rough sand can create quick wear and tear on the fabric. If you have environmental concerns, you may want to repair the chair rather than discarding it right away and adding your personal landfill contribution. Replacing the fabric is easy to do.
