No back support
After some extensive searching online for a comfy seat to cush my tush, i came about this site. Based on the reviews i purchased two of these seats. i would not purchase additional seats. although the padding is nice and the zipper compartment is great, there is no back support at all. the backing is almost useless. in addition, carrying the seat via the strap is awkward. the seat is very light weight, so that is a plus. if you are looking for something with back support, do not purchase this item.
