I'm pretty sure we want to get a Boon Flair and have listed our Tripp Trapp on CL. But before we sell the Tripp Trapp I'm curious whether there will be a gap between when he outgrows the Flair and can sit in our regular dining chairs? (We have Panton chairs, so they're not very accommodating to booster seats, I imagine, having curved surfaces.) If you've used the Boon Flair at what age/size did your LO outgrow it or do you think it'll happen?
