Small side

I read other reviews before making my purchase.I read they ran more on the smaller side , which was perfect for me. So , I ordered anyways and it fit my antique high chair perfect. My highchair didn't have straps so this served its intended purpose. I am shocked at how good the material quality is. Very affordable. Will NOT fit a normal size chair... Imagine a child's chair back. I don't even see this fitting a normal sized high chair but I could be wrong. I personally love it and it holds my 9 month in place.
