When I started looking at high chairs, my main concern was being able to open the tray with one hand. I did buy the one that was easiest to use, one handed. It has held up for 5 years and made it through 2 children! The tray is still easy to use! On cleaning - the front of the tray and the top of the seat is easy to clean. The fabric seat cover was very easy to remove, clean and replace. The underside of the tray, sides of the high chair and under the seat are very hard to clean. There are just too many little areas that you can not get into with fingers. The back is adjustable. It seemed like a great idea. We ended up using a bouncy seat for infant feeding, not the high chair. During the first child's use, the back started "leaning back" on it's own. during the second child, it really became a problem with the back of the seat tilting backwards on it's own. it seemed that the brackets in back would just not stay in the tracks I wanted it in. It also came with a plastic "second tray" that snaps onto the main tray, I never used it.
