Longer answer: if you're a taller person you probably need more elevation below your rear end. Your weight should be distributed between both knees and your rear end evenly. For taller people this is harder: we tend to not get enough elevation under the rear end (it doesn't "look right" and they don't make cushions tall enough), so we rest a lot of our weight on the leg that is tucked under instead of getting our knees low enough. This disrupts the triangle that creates the stable posture, and it also causes the leg to fall asleep. So if you're taller than say 5'8“ try using two cushions beneath your rear end and see if that helps.
