I'm looking for a booster seat/feeding chair (ideally with a tray) that will work on this type of bar-height chair. Most boosters say they won't work on padded seats. Our chairs are learger covered, but not very cushy.

Has anyone successfully used a booster on this type of chair? If so, which one?

We currently use a Bloom Fresco Loft high chair, which is awesone, but DD2 needs to move out of the bumbo and into a real seat, and DD1 isn't ready for a regular seat at the table...I'd rather not buy a second high chair. In fact, if I'm happy with the booster I may buy two and ditch the high chair, so I'd love something that fits both an infant and toddler, if that exists!
