BERG is the Champion of Trampoline Safety and Fun! The BERG In-Ground Grand Champion Oval Trampoline offers top safety, performance, and quality for long-lasting fun. The oval shape combines the strength of round trampolines with the top performance of rectangular trampolines. The exclusive AirFlow mat allows 50% more air permeation which enables easier and higher jumps due to less air resistance. The TwinSpring Gold Springs are rust proof and placed diagonally around the mat to create a larger "sweet spot" than other trampolines. The strong galvanized rust-proof steel frame includes a 10 year warranty. The Deluxe Safety Net is supported by padded curved steel poles to provide a safer distance between the poles and the netting along with a carbon fiber top ring to keep the net structure in place. The Deluxe Safety Net also features very small holes to prevent any finger injuries and includes a self-closing entrance for added safety. The green PVC padding is extra wide (15") and thick (1.25") for comfort and safety and is resistant to fading.
