To start with I purchased padding at the local craft store and cut it fit our fireplace.
I used Velcro along the back side of my cushion so the fabric could be removed if necessary (like for washing). And I found that while cutting out and around the actual fireplace insert for the cushion did take more time it looked a lot nice that not doing so.
I added a few pillows and skirting to front and sides of the cushion to cover up the rest of the bricks. I did this mainly as another layer of protection for MacchiOTTo but also because I thought it looked nicer, however you could easily omit that and just do the cushion.
