I pop this gate in and out in a minute for use in different doorways depending on where I need it.
It's height makes it difficult for my medium-large dogs to jump, the metal meterial makes it impossible to chew through and the small door makes it easy for our cat to get around the house still. It comes with optional screw in brackets to use for addt'l support and all 5 of our dogs can jump on it without bringing it down!
