I was looking for a portable high chair or booster seat for my upcoming travel and came across this deal at Kollektive. I saw that this particular product is commonly listed as one of the most portable high chairs as it folds almost completely flat and reviews are generally pretty good. Got mine delivered a few days ago and it looks pretty solid and good quality.
Bombol's website and other retailers sell this at $192-$199 so I think $99 is a pretty decent deal. Both the grey and blue models are on "low stock" at the time of posting.
Nice first post, OP. Free shipping over $100 if you can find something cheap.
