Here are some stairs I designed for our 14ft trampoline. They can be scaled to fit different sized trampolines. These are meant for small children to help them get on and off safely. The stair path is only 15" wide with 16" high rails. The design can be made using roughly 6 common 8ft 2x4's, with an adjustable square, screws, wood glue and a circular saw. Enjoy!
