My little boy is a smelly little one. When he sleeps, he drools & sweats a lot... His sheets get pretty nasty, pretty quickly. But, I never would change them as often as I should. It was just such a chore. Sometimes the mattress gets really stuck. I often need Scott's help. It was just really hard. But - not anymore. I just got the Quick Zips. This chore no longer exists. It is a breeze to change his bedding! Check the out!
