Hi Lesley, Thank you for your enquiry. The Airwrap is designed to be breathable to address the issue of suffocation. Although baby can still bump the sides of the cot as the material is a thin mesh, with the Airwrap the bumper surface is flat so they cant knock themselves on the edge of the rails and little arms and legs can’t get stuck between the rails. So although it is not padded it does protect your baby and keeps them safe. I hope this helps with your query.
