Depends on the store. To get the best service go to a locally owned baby store.
You didn't say how old/heavy the child is.
I've had a look, All the high back, 5 point harness style seats, are similar in design. A one piece injection molded shell with stiffining ribs on the back/bottom. I didn't much care for that.
If the kid is 4-5 years old, believe it or not, one of the least expensive, was the best, as far as leather damaging potential goes. It's a simple styrofoam cushion with a cloth wrapper.
