Trampoline legs support the horizontal frame member above a ground surface. A trampoline enclosure supports a trampoline enclosure net from a spring enclosure netting support. The trampoline enclosure surrounds the trampoline bed and the trampoline enclosure is supported on a trampoline pole. The spring enclosure netting support is formed as a leaf spring. The leaf spring is flexible in a horizontal direction and in a vertical direction. A leaf spring vertical dimension is greater than the leaf spring horizontal dimension.
