In addition to being extra wide, the BERG Champion edge cover is also extra thick. This gives greater protection. The springs are attached to the jumping mat by triangular hooks and secured by a full 8 rows of stitching. The frame is galvanised on the inside and out to make it rustproof.
BERG Toys has developed a unique spring, the goldspring. It enables jumping energy to be built up gradually so that the forces on the body are gentler. This means you can jump higher, more comfortably and more safely.
