Living in New York City I consider myself lucky to even have a dining room albeit a small one. Choosing a high chair for our son was actually an easy decision since we needed something that would make the absolute smallest impact in this undersized room.
Since the Me Too attaches to the table, it doesn't use any floor space which is nice from a practical standpoint as well as visually. It's easy to sweep or, in many cases, mop the floor under it and the chair itself gets wiped down after particularly messy meals and scrubbed in the bathtub every few weeks (or before my mother visits; whichever comes first).
My favorite feature of the Me Too is how portable it is. We haven't taken it to a restaurant yet (as many parents do), but it goes on every overnight trip and we use it on the picnic table in our mini-backyard. It comes off the table in a few seconds and folds flat so you really can tuck it in a large bag. We also enjoy the feeling of having our son right at the table with us both to share meals or play games. We often sit at the table with him and even get a little work done on our laptop as he gets "work" done with his toys.
This style of highchair (there are others besides the Me Too) really works for us in our small apartment. What's working for you at your small place?

We have a weird table that the Me Too wouldn't work on. We almost got the Handi Sitt but ended up getting the Svan. It takes up very little floor space compared to the other chairs we saw but I liked that it had its own tray.
We have the Me Too and love it. Super handy. Other than that, we have also used the fisher price healthy care booster that was on here a couple of days ago. And our other favorite is the cushie booster, which can go on any seat and is soft and squishy. I know it seems cuckoo to have three different boosters (we do have three kids too) but they all seem pretty essential depending on the stage your kid is in. And we never missed having a high chair. Those things are huge and a pain in every way.
We too love the Me Too, but my only complaint is that the canvas seat doesn't come off to be able to wash it. Any solutions anyone?
We have a Fisher Price Space Saver high chair, which turns into a booster. I'm not sure how much space it saves, really, because now we just have one of our dining room chairs in the middle of the room instead of pushed under the table. But it works. It is a bit smaller of a footprint than some high chairs I've seen.
We also have the MeToo chair. Love the concept, but haven't used it yet because when we tried, the table didn't have enough of an overhang to attach it. Though I'm sure we'll use it a lot this summer.
We got the Me Too seats for our twins and it worked for a bit but we had to move them around for diff feeding configurations (depending on if one was feeding two etc)
In the end, I got two Ikea high chairs that are cheap and lightweight and never looked back. I can easily push them to the kitchen if Im cooking or the living room if Im relaxing (as if)
I love this chair. We got it when our first son was born and it's still going strong for a second son, 4 years later. I love that it's simple, no bells and whistles. The arms fold up nicely and the entire chair can fit in most mid size diaper bags. I take it with us whenever we go out to eat and it's a godsend because our son loves to feel like he actually at the table with us. If you need to clean it just run it under the sink and scrub. It will dry overnight. Comes clean with ease.
I have a couple of metoo chairs (three kids under three) but rarely use them, primarily because you have to have a certain type of table and they are difficult to clean. The Fisher Price Healthy Care booster is pretty unattractive, but great for small spaces and for ease of cleaning - it just straps to your dining room chair(s), has a tray for the months before the little one(s) can sit at the table, and it goes into the dishwasher for cleaning (I do this weekly and just wipe it down in-between). And, you can just push the chair into the table when it's not in use so the plastic-ness of it is not on full display. It is hands-down the best solution I've found for our small space.

CPSC Alert: Consumers Urged To Stop Using phil&teds USA Clip-on Chairs Due To Serious Dangers Posed To Children
The company has refused to agree to a national recall of their hazardous product that is acceptable to CPSC. The company has offered a repair kit consisting of rubber boots to place on the upper clamp grips of the chairs. Consumers should be aware that CPSC has not approved a repair kit for this product, despite the firm’s prior statement that it was conducting a recall “in cooperation with the U.S. Consumer Product Safety Commission.”
