Up until this point, my 2.5 year old has used our Oxo high chair and my now 11-month old has used the Bumbo during meal times. Well, the younger one has outgrown the Bumbo (can't believe it lasted us so long) and we would like to put her in the high chair, and bring the older one to the big table with a booster.

The issue is that we have retro style leather swiveling dining chairs, and I am concerned about what kind of booster will fit on them.

What do you use? Should I find something that somehow straps onto the chair or under them? She's petite and I think it is something she will use for a long time...

TIA!

ETA: I was considering something like this, but I don't think it provides enough "boost" for her to eat comfortably at the table, and since our chairs are leather and rounded, I think it would just slide off.
