Query: Tray is a pain in the neck

I received this booster seat as a shower gift and while I love the convenience of it, I have to admit that the tray is nearly imposible to get on and off which makes it less of a convenience and more of a hassle. My mother in law has the booster seat made by The First Years and is much easier to use. I called Safety First to get a refund and they would only refund me the manufacturer's cost without proof of purchase. Who has proof of purchase when it was a shower gift and now your child is 18 months old. What choice do I have now? Keep it or get less for it. Overall, I have been pretty unsatified with ALL Safety First products.
