IKEA has the best baby gates- hands down. My whole family has bought several of them over the years (for kids and pets). We have at least 5 in our house right now. They have white metal and wood ones. We only have the metal ones. I think they are about $35. They are pressure mounted and open up easily for adults but kids can't figure it out. Love love love them.
