When Im worried about my legs falling asleep, I roll up my yoga mat and sit on it, letting your knees rest more lightly on the floor. It lets your hips be a little more extended and comfortable, allowing you to sit in that position for longer periods of time.
Spot on!
As an avid practitioner of Yoga and meditation, I totally agree with your advice.
