I have the contempo high chair (but not the winnie the pooh patterned one - wish we did, I love it! So adorable).
Pros: removable tray cover made for easy ish cleaning, fold flat design was very nice for storage, seat cover did wipe clean relatively easily, sturdy design
Cons: removable tray cover didn't cover the sides of the tray, so I often washed the entire tray, seat cover was not machine washable and I really wish I could just toss that thing in every once in awhile, cover also had a lot of crevices that got pretty nasty and were difficult to clean
Other thing to note is that it has a little snack tray underneath the normal tray, which was nice for a quick dry snack between meals. Only thing annoying about this is that it made the seat a bit more restrictive to get the kid in and out and as a result my daughter outgrew this at a relatively early age (17 months) due to her long legs. You can adjust the height to allow them to eat at the table with you rather than on their own tray, which would have been awesome if my daughter fit into it longer. Also the foot rest is designed weird and may as well not be there (sits too far back).
Overall not unhappy but if I have extra money when we do kid #2 I may decide to replace it.
