Do you use a breathable bumper? We bought one from target and the installation is really annoying me. Firstly I didnt realize it was gonna be in 2 pieces, so no matter how I install it the "breathable" fabric overlaps. At some points its like 4 layers of fabric, so it cant be breathable all around then? I watched the installation video and I'm doing it exactly as the described. If you use a breathable bumper does yours overlap a lot
