This extra surface allows children to lie flat or elevate their legs for improved comfort during sleep. It's also a perfect platform for play, providing space for toys and relaxation. Adults can benefit too, using the cushion for better posture, sitting cross-legged, or changing positions for added comfort. - Versatile Height Adjustment: The double cap valve allows you to customize the height. Inflate just the lower chamber for a lower level, the upper chamber for a mid-level, or both for maximum height. The specially designed valve ensures quick and easy inflation. - Lightweight and Portable: Weighing only 0.8 lbs, this footrest conveniently folds into a compact 9"x10" drawstring bag for easy transport. When needed, it inflates to a spacious 17"x12"x18", providing comfortable sitting or floating options. - No Pump Required: Our tests show that inflating by mouth is quicker than using a manual pump, eliminating the hassle of carrying a pump and minimizing noise during your flight.
