Query: BAD tray design

If you are just using the seat at the table, this booster is fine. However if you want to use it more as a high chair, look elsewhere. The tray is impossibly difficult to snap onto the seat and also hard to get off. The white top tray designed to keep the bottom tray clean is too easy to remove so the baby will just pull it off and make a mess. As a seat, it's OK as long as you are putting your child at the table and rarely using the tray with it.
