We had the BEST baby gates!!! they were expensive... But boy to me, they were worth it! I do not remember the maker, I think they were made in Europe, maybe Sweden. We got them at the Baby Superstore, now BabiesRus. they are white powdercoat painted metal, and look like porch or verandah railings. ( Very NON babyish, they work so well with any decor.) One side is hinged, and screwed firmly to the doorjamb, while the other side latches-unlatches, with one hand, to swing open.
The biggie for me is to get one that does actually attach to the doorjamb..... The Tension Spring types are such a pain!! Having to be totally removed and reset EVERY time you go thru!
These were GREAT, I highly recommend them, and I would buy them again!
