ours is an extra high one. We got it because DD is tall and we didn't want her to be able to open too early. It has a latch at the top that you have to push down and lift. It also has a lock on one side. My DS is an average sized 20monther and can't reach the top.....but I can't tell you the brand cos DH is on night shift and asleep where the gate is.
Will BBL with an update though.
