Before purchasing lawn chair webbing, you will need to determine what size webbing you need, as well as the color you want. Vinyl, nylon, and polyester are materials commonly used for lawn chair webbing, and all three will be waterproof and strong enough to be used on any chair. Remember that lawn chair webbing is not commonly used, as this style of chair has essentially gone out of style, but a thrifty homeowner can save money by replacing damaged webbing instead of simply throwing the chair out. Since webbing is out of style, it may be difficult to find as well.
The two most common sizes of lawn chair webbing are 2 1/4 inch (5.7 cm) and 3 inch (7.62 cm). Very old chairs were more likely to use 2 1/4 inch (5.7 cm) webbing, while more recent models were likely to use 3 inch (7.62 cm). Be sure to choose the right webbing before purchasing; simply measure the current webbing size already mounted on the chair and purchase the similar size. Purchasing the wrong size can make re-weaving the chair more difficult, and you may end up with excess material. If your chair uses plastic tubular webbing, you may want to consider switching to wider nylon or polyester webbing for strength and durability.
Lawn chair webbing often comes in rolls, and the roll length will vary according to manufacturer or seller. Be sure to buy enough webbing for your chair or chairs. This may mean purchasing more than one roll to accommodate many chairs, or just one roll for part of one chair or one entire chair. It is a good idea to buy a roll with more material than you need, not only to have spare material for future repairs, but also to have extra material should you make a mistake and need to cut a new length.
When you replace lawn chair webbing, it is a good opportunity to change the appearance of your chair if you want to. You can buy a different color or design of webbing than you had on the chair previously, and you may even consider purchasing more than one color of webbing to produce a different weave appearance. Lawn chairs that use webbing tend to be quite old, and it is likely that you will not be able to find an exact color match anyway, so consider carefully how you want your chair to appear once the project is finished.
