I have a Combi daybed which is multi-functional. It serves as a rocker, daybed and high chair. It is also reclinable and adjustable to different heights and can be pushed around the house on wheels. I also have a Fisher Price high chair which is foldable and reclinable, though not as much as the previous one. A lot of moms use the basic IKEA high chair but it is rather unstable but it's cheap. Some tips on choosing a high chair: http://sg.theasianparent.com/how-to-choose-a-baby-high-chair/
When baby is younger, I used ikea baby chair with tray. When they get older, I let them dine on children's tables and chair, in kitchen so they can be more independent. Also, baby chair is not very safe when baby tends to stand up and struggle even when buckled up.
thanks
