A stretch strap of a chair has multiple stretch ropes and a soft sleeve. The soft sleeve receives the two stretch ropes therein. Each stretch rope has multiple rubber cords and a covering layer binding the rubber cords therein. Since the covering layer is a weave, so there are gaps on the covering layer and a concave is formed between the two adjacent stretch ropes, when the stretch ropes are tied together. However, the woven covering layer is inside of the soft sleeve, the soft sleeve prevents dirt from receiving in the gaps and the concaves. In addition, a chair user directly sits on the soft sleeve not on the woven covering layers and feels comfortable.
