We're going to be in rented accommodation for the foreseeable future and DS has got to the stage where stairgates are now a necessity! Are there any about that don't require some sort of permanent fixing to the walls/newel posts? I've got one via a friend but it has wall cups that have to be either screwed to the wall or stuck with adhesive pads. I'm guessing that when we come to try to remove them, they'll either not come off or leave ugly dints in the plaster work and then it's bye bye deposit. Any thoughts? Thanks
