I'm not a fan of the ikea ones at all personally.
I have a love and care one, it has a round heavy base, wouldn't recommend anything like that if you plan on moving it around! Dd is 2 and I'm now looking at buying a cheaper one that folds up bacau we I can't move the one I have now by myself!!!
Also make sure you can fit a dinner plate on the tray, not a big deal when they are young but so frustrating when they get older.
