When evaluating safety air cushions, prioritize material durability and inflation speed. Look for high-tenacity PVC-coated polyester or aramid fibers that offer flame retardancy and high tear resistance. The internal structure should feature a dual-chamber or multi-cell design to ensure that if one cell is punctured, the cushion maintains its structural integrity. Additionally, verify the maximum fall height rating (e.g., 16m, 30m, or 60m) and ensure the recovery time between jumps is less than 20 seconds for emergency efficiency.
