Thank you for viewing! ⭐️ This is a Farska baby anti-rollover cushion. I used it by placing it between my husband and me. When sleeping with my child, I was worried about accidentally rolling over and squashing them, but this cushion eased my anxiety. You can adjust the position of the triangular parts by using the Velcro to make them narrower or wider. The white part of the mat has some fuzzing and pilling due to the Velcro. Please check the photos. I have discarded the outer box, so I will pack it compactly for shipping. This is a used item stored at home, so please purchase only if you understand.
