First of all - THIS FIREPLACE IS NOT USED AND NEVER HOLDS A FIRE OF ANY TYPE. It actually has a fake fire that uses a light bulb and rotating gizmo for pretend fire - no heat - no worries. If you use your fireplace - you must remove any and all type of cushions, pillows, blankets, papers, plastic, etc. - Anything that would be flameable. Use Common Sense - Stay Safe Everyone!This is my second Fireplace hearth project. The first hearth cushion project I created is on HT (https://www.hometalk.com/diy/build/furniture/have-a-seat-please-38157277) and was a project involving redoing what my daughter and husband had originally created to project their young toddlers from sharp edges. It was also a fireplace that was not used for fires of any type. Those same toddlers that were the inspiration of the first cover visit my house so I wanted to soften the hard rock edges giving them some protection along with creating a favorite corner to hang out in.
