Seal and Buckle Ends

What happens here

Bring the two open ends of the lounger together, gripping the fabric firmly. Roll these ends over several times, creating a tight seal that prevents air from escaping. Once rolled sufficiently, connect the male and female parts of the built-in buckle to lock the rolled ends in place, maintaining the lounger's inflated state and shape.

Goal: Once inflated, tightly roll the open ends of the lounger and secure them together using the integrated buckle to seal the air inside.
