After months and months (literally, over 4 months!) of stalking this high chair on CL, I just found one on the street right next to our apartment! Wahoo! And it's in great condition!

Side note: you know you've truly gone over to the dark side of parenting when finding a high chair makes you out-and-out giddy!

So, my questions are:

Do I need to get the baby set? My twins are one year old.

Is this harness enough or should I look for the 5-point one?

Should I get the tray?

How do you adjust the height of the seat and foot rest?

Do I need to get the adjuster-things that are supposed to help it from falling backwards?

The date on the bottom says 10.10.03 and there's a serial number that I know is relevant to what the chair is compatible with that I can post if that's needed info.

Here's a pic of the chair for reference.

Thanks so much!!
