The Hearth Gate was deigned to protect small children from fireplaces and even heaters.
It consists of 6 panels that are each 60cm wide and 75cm tall. One of those 6 panels is the actual gate to let adults through.
Each of the 60cm panels can be removed if you wish make it smaller. If required, you can also purchase additional 60cm panels to make it bigger!
The best news is that each panel is joined to the next panel with a Push Button Ratchet Mechanism that adjusts in 10º increments to give the required shape you want. As such, you can turn it into a hexagon and use it as a playpen, or turn it into almost any shape you like to completely close off a fireplace or heater.
