What You'll Need
About Your Order
Your sling fabric is custom-cut to your exact measurements. The spline cord included with your order arrives as one continuous piece that you will need to cut to the length of your channels.
Step-by-Step Guide
Remove the Old Sling
Carefully remove the existing sling fabric from your chair frame. Pull the fabric out of the channel on both sides. Discard the old sling — measurements should always be taken from the frame, not old fabric.
Measure the Top Width (Back of Chair)
With the old sling removed, measure the distance from the center of the left rail to the center of the right rail at the top (back) of the chair. This is your "Top Width."
Measure the Bottom Width (Front of Chair)
Measure the distance from the center of the left rail to the center of the right rail at the bottom (front) of the chair. This is your "Bottom Width." On many chairs, the front is wider than the back, creating a trapezoidal sling shape.
Measure the Length
Measure from the top of the top rail to the bottom of the bottom rail. This is your sling length. Measure along the frame rail, not across the open space.
Measuring Two-Piece Slings
If your chair has a separate seat and back piece (with a cross bar in between), you need to measure each piece independently.
Seat Piece
Measure from the bottom rail (front of chair) to the cross bar that separates the seat from the back. Measure the width at both the front and back of the seat section — center of rail to center of rail.
Back Piece
Measure from the cross bar to the top rail (back of chair). Measure the width at both the top and bottom of the back section — center of rail to center of rail.
Common Mistakes to Avoid
Measuring the old fabric instead of the frame — fabric stretches over time and won't give accurate measurements.
Forgetting that top and bottom widths can be different — always measure both.
Measuring the outside or inside edge of the rails instead of the center — always measure center of rail to center of rail.
Not measuring two-piece slings as separate seat and back pieces.
