Stokke Tripp trapp high chair accessories?

Does anyone have the Stokke Tripp trapp high chair? What accessories do you suggest? I think I want the tray because I think it would be easier to clean up than our wooden table, but are any of the other accessories nice? I’m considering the newborn seat so that we can have baby near us while we eat, but it’s expensive so I’m wondering how nice it really is😬 And what about the seat cushion? Is that nice, or is it just one more thing to clean? There are so many add ons available! What accessories (if any) did you actually buy and use?
