We have an IKEA antilop - £15 everyone swears by them and a Stokke Tripp Trapp (£100 second hand on eBay).
We've never fed DD in the antilop. Just use it for sitting in the kitchen. Love the Tripp Trapp. Dd Can sit at table with us and eats food straight off plastic table cloth. We are doing baby led weaning and it's brilliant!!
