I searched all around to try to find out if the side impact cushions on the Britax Advocate 70 CS child car seat are removable. I couldn’t find anything, so I went ahead and looked. It turns out that each cushion is held on with 3 Torx screws that are located on the inside of the seat underneath the cover and foam.

I guess this is not widely touted, because people buy this car seat specifically for those cushions and probably don’t typically want to remove them. For us, we wanted to remove them, because we’re going on a plane tomorrow and we don’t want those side cushions taking up extra space. Fortunately, they’re easy to remove.
