I agree and quite rare to get the rears as-well

.
Your right they look a little out of shape / saggy, they don't seem to have the frames with them (rears) they look like they're just the covers, as long as there OK it will just mean a little effort changing the frames over

.
The fronts don't have the runners but this is normal as they're supplied without them

, again a little work involved changing them over
