My sister had this highchair for my niece...it is a good one, but it takes up a lot of space. I was her nanny for a few months, and I liked the fact that the highchair had rollers, and the harness. But putting the harness on takes even more time and with a hungry screaming baby sometimes it was frustrating. Otherwise it is fine...but I am not sure I would pay $140 for it!
Personally I tried several highchairs. I liked the folding Avalon one I got from my other sister [I think it was from Target] until my sons legs were too big for it. It folded flat and was nice and simple and easy to clean. I tried an Evenflo one with a back that you could adjust to tilt back for a baby that can't sit up yet. That one had rollers which was good but the rest of it was badly designed. I also tried [and still have] a restaurant style wood high chair..but that is not a good one until they are older since they have to sit at a table and be trusted not to throw food.
The one I ended up sticking with was from a garage sale...it is a Gerry brand older style, probably from the 90's. It is not "cute" by any means but I love it. The best thing about it is it has a padded vinyl seat, adjustable footrest, and a nice big tray with high sides that is easy to get on and off. I definitely suggest getting one with a big tray with high sides that is easy to take on and off, and a padded seat that is easy to clean is another must. Since it is comfortable to sit in my son doesn't mind it for other things...I put him in it to color, play with play dough, watch Baby Einstein, etc
My son is 17 months and I still use the highchair because he likes to wipe his food all over with his hands at the end of the meal. We call it the "window wiper". I just can't trust him to be in a booster seat at the table yet.
I like to figure out the monthly cost before deciding if something is worth the money. If you figure most babies don't sit up on their own until at least 6 months and you will use the highchair until your child is 18 months to 2 years, that is 12-18 months of use if you don't switch to a booster earlier. You would be paying $9-13 a month if you go with the Chicco one...and you can also resell it after you are done with it [probably for $25-35] but that is still $7-11 a month for a highchair. I got mine at a garage sale for $5 [28 to 42 cents a month]....but say you get one for $15 it would only be 84 cents to $1.25 a month for the time you will use it [assuming you even use it that long...maybe you will want to buy a booster before 18 months in which case the cost per month would be higher yet]. If you figure out all of the things you are buying for baby that way, you can see how it fits in to your monthly budget and if it is really reasonable compared to the cost of other things. Personally I don't see a point in buying anything new, because the time it will be used is so short that it just doesn't make it worth it for me when I can get something much much cheaper used [especially clothes...I would not even pay $5 for an outfit..at least not until my son gets to be older and wears them for a longer time]. But if you plan on having more kids and are hanging onto things that changes it a bit.
If you do really want the Chicco one I would at least check craigslist and Once Upon a Child first to see if you can get it cheaper
