We need a stair gate in anticipation of a child and to prevent the dog from getting muddy foot prints all the way up stairs. Our stairs have 1970's diagonal banisters and a window at the bottom so we will need to put the gate 3 steps up. We can't block the bottom of the stairs as the front door is in the way. I have read various reviews about the Kiddicare retractable gate from really good to don't touch with a barge pole, plus is it three times the price of most others. Is it really that difficult to open one handed? And has anyone got any other suggestions?
