Pillow gravestones are available in 16", 24" and 28" wide versions. The concrete bases are made of grinded concrete that results in an attractive exposed rock finish. They are a little easier to read than a flat gravestone. The standard granite plaque is .5" thick with 1.25" thick as a option. Photos are a popular option. They come with a standard base with an additional bigger base for situations where the ground is soft. They can easily be installed by two reasonably strong people. ,
