This anti-rollover cushion is suitable for newborns up to 9 months old. It's easy to use in just 3 steps. I purchased it on Amazon, but I'm selling it because I didn't use it. It's brand new and unused, still in the box. Thank you. - Brand: GUSUMIN - Target Age: Newborn to 9 months - Features: Anti-rollover cushion - How to Use: Easy 3-step usage - Included: Instruction manual - Color: White Thank you for looking.
