Outdoor sling chairs are popular for their modern style, breathable comfort, and easy maintenance. However, after years of exposure to sunlight, moisture, and general wear, the sling fabric can sag, fade, or tear. Instead of discarding the entire chair, replacing the sling fabric is a cost-effective way to restore its look and function. With the right materials and a bit of patience, you can give your outdoor sling chairs a second life.

Understanding Outdoor Sling Chairs

Sling chairs feature a durable fabric stretched tightly across an aluminum or steel frame. The fabric — often made of textilene, PVC-coated polyester, or olefin — provides both support and flexibility. Over time, constant exposure to UV rays and weight stress causes the sling to lose tension. Replacing it requires precision to maintain proper alignment and comfort.

Step 1: Gather the Required Tools and Materials

Before starting, prepare everything you’ll need for the replacement process.

You will need:

• Replacement sling fabric (measure to fit your chair model)

• Spline (vinyl cord that holds fabric in frame channels)

• Scissors

• Tape measure

• Screwdriver or Allen wrench

• Pliers

• Utility knife

• Sewing machine (optional for hemming)

• Rubber mallet (optional for adjustment)

Always use outdoor-grade sling fabric that resists UV damage and moisture. Textilene or PVC-coated polyester is the most common choice because of its strength and elasticity.

Step 2: Measure and Order Replacement Fabric

Accurate measurements ensure a snug fit. Measure the width between the inner edges of the sling rails and the length from the top to the bottom bar of the chair frame. Subtract about 1 inch from the width to account for fabric tension when installed.
Most sling fabrics are sold by the yard or pre-cut according to chair dimensions. When ordering, include matching spline size — typically between 0.125 to 0.25 inches in diameter — as it must fit securely in the chair’s frame track.

Step 3: Remove the Old Fabric

Lay the chair flat on a clean surface. Use a screwdriver or Allen wrench to loosen the bolts or screws that hold the sling rails in place. Gently pull the rails away from the frame — avoid bending them. Slide out the old fabric along with the spline using pliers. If the fabric is stuck, cut it into smaller sections for easier removal.
Once removed, clean the rails and frame thoroughly to remove any dirt, rust, or debris before installing the new sling.

Step 4: Insert the New Fabric

Place the new fabric on a flat surface with the good side facing down. Insert the spline into the hemmed edges of the sling fabric. If your replacement fabric doesn’t have hems, fold each edge about half an inch and sew a straight line using strong polyester thread to create a channel for the spline.

Slide one side of the fabric and spline into one rail channel. Repeat for the other side, keeping the fabric straight and evenly aligned. Some resistance is normal — use gentle pressure to avoid wrinkling.

Step 5: Reattach the Sling Rails

Once the fabric is in place, reattach one side of the sling rail to the chair frame with its screws or bolts. Then, carefully stretch the fabric across and align the second rail. You may need a helper to hold the fabric taut while you insert screws on the opposite side.
To achieve proper tension, start tightening screws from the top and work downward. Use a rubber mallet to tap the rails gently into place if needed. The fabric should appear tight but not overstretched.

Step 6: Trim Excess Fabric

After the sling is securely installed, trim off any excess fabric sticking out beyond the rails using a utility knife or sharp scissors. Wipe the chair frame clean, and check for even tension and alignment. Sit on the chair to test comfort — it should feel firm, supportive, and evenly balanced.

Step 7: Finishing Touches and Maintenance

To maintain your new sling fabric:

• Rinse it regularly with mild soap and water to prevent dirt buildup.

• Avoid leaving the chairs under heavy rain for extended periods.

• Apply a UV-protective spray once or twice a year to preserve color and flexibility.

• During off-seasons, cover or store your chairs indoors to extend fabric life.

Common Mistakes to Avoid

• Incorrect measurements: Even half an inch off can make installation difficult.

• Skipping spline replacement: Old splines lose elasticity and won’t hold properly.

• Overtightening screws: This can warp the frame or tear the new fabric.

• Using indoor fabric: It will fade or weaken quickly outdoors.
