I recommend the Svan. It looks like the Tripp Trapp, but it has a tray (removeable) which is really really useful. You may want to use it somewhere other than at a table one day! Also, I buy plasticized fabric by the metre from John Lewis and cut lengths to put under the chair. You can chuck iit in the washing machine, it's inexpensive (and comes in a range of funky patterns) and when it's really too far gone to wash - check it and cut another bit off!
