I look at the micro suede, and think how well weetabix will stick to it. Far too many crevices to clean too.
IMO, there are two sensible high chair choices - an Ikea Antilop or a Tripp Trapp. I have both, and the Antilop is so easy to clean - you can even sling it in the dishwasher if needs be, but there is literally no where for food to get stuck. The TT is brilliant long term, esp as they can climb into it themselves once the baby set is off
