The cover fits snuggly iver a carseat. However, I find that the fit is too snug to comfortably nurse under. In addition, I selected the cotton/rayon option, but the cover appears more synthetic to me, which makes it quite hot to nurse under, especially in the Namibian summer heat. Given how hot it is, I wouldn’t use it as a car seat cover on a hot day. Overall, I think it works quite well as a car seat cover under the right conditions, but I personally would not use it as a nursing cover.
