Tianjin Rostone Fitness Products Co., Ltd.

We began to manufacture trampolines from the Jump trampolines in 12 years ago. They were the best trampolines on market in 7 year ago until we put Elite and Pro trampolines into market. Now, they become standard trampolines.

A lot of manufacturers lower the quality in order to reduce the cost as much as possible. It is a dangerous way to do business of trampolines. We don't reduce the quality to burst our sales. We keep on using the good materials for our Jump trampolines, and put some advantages of Elite and Pro trampolines on them in order to improve the quality. Thus, our Jump trampolines is better than the standard trampolines on market. We think we can keep our customers longer than others by our good quality.

We have TUV/GS certificate for our Jump trampolines.
