For the 10 months of DD's eating we have been using the Bumbo with play table. Fantastic! I sit her up (yep I know I shouldn't) on our bench on it and she is happy as she is part of everything.
A GF of mine has the Fisher Price Space Saver high chair and loves it.
We have just put DD now into our high chair we have had since DS1..the Fisher Price Healthy Care high chair..it's been great and lasted well with all three kids. I love the fact I can take the cover and straps off completely and throw in the washing machine.
And yep..the Ikea ones are great, they are used in Play Centres as they are easy to clean and safe to use.
