My in-laws have the IKEA Antilope for when LO is over there...it is great in terms of cheap price and easy to clean, and you find them in many restaurants.
However, they have the space in the kitchen and so they never pack it away- as a result, I think that all the adults at some point have tripped over the legs as they splay out quite a bit.
Luckily LO was only sat in there on one occasion...but you can imagine a 6 foot plus grown man tripping over one of the legs! 
I prefer a wooden highchair at home (Stokke Tripp Trapp)- it is so easy to clean, you adjust the size as LO grows. It is possible to buy a separate tray that attaches or you can bring it up to the table.
They are pricey but if you look on ebay/local listings, you can get them for a reasonable price second hand (I bought most of the bulky baby equipment second hand- cot/bed/changing table/pram pushchair- this was with my firstborn which I guess is a bit unusual, judging by our friends & acquaintances, we were almost the only ones who did this!)
When it's not in use it can be left at the table like an ordinary chair- I love it as it looks like a normal piece of furniture and LO will be using it for years to come!
