Double Bounce Trampolines produces two models of trampolines for backyard fun. The Original, and the recently introduced Deluxe. The Deluxe model introduced several safety features that were intended to scare overly protective parents into upgrading. Since its introduction, the deluxe model has been increasing in sales, but at the same time, the companys profits have been declining.
