S.H.
we made our own gate. "Picture frame" style for the 3 pieces (across the front of the hearth & 2 sides), which are attached together with hinges. We filled the frames with lattice. Been using the gate....really it's a fence!....for the past 8 years for my inhome daycare.
The ends of it are not attached to the wall. Instead we use furniture to keep it in place. This simple wooden style works well with our home filled with vintage & antique pieces.
