the Ikea Antelop does come with a tray which is simple to snap in and out, but also very stable! I really love mine to pieces! I'm so glad I didn't waste money on a high chair - as other said - my DS only needed one for 15 mo max, and then it was on to a soft booster seat (thank you Mothercare) on top of one of our regular chairs.
Spend the money on something else!
