Before you begin:

Off with the old. Cut off worn-out straps and remove the screws or rivets from the frame.

Do the math. Determine how much replacement strapping you'll need. Measure the distance from the back of the hole on one side of the frame to the back of the hole on the other side. Then multiply these measurements by the number of straps you'll be replacing.

Purchase replacement parts. Get new straps and fasteners from a furniture repair store or garden center. The staff there can cut each strap to your specifications and make holes for the fasteners.

Replace the straps:

1. Soak the straps in hot water until they're flexible.

2. Push a fastener through one of the holes in the strap and then attach it into the hole on the back of the frame.

3. Pull the strap across the frame, wrap it around to the back, and push another fastener through the strap and into the hole. Make sure to hold the strap taut while securing it to the frame. The strap will stiffen as it cools.
