These amazing pads are 100% organic cotton with untreated cotton filling that is needle punched so they can be machine washed and dried often without bunching. I use these in my dog crate and to protect areas my dogs lay on. Like on my chair. They are absorbent and pure.  
These are about 1/4" thick or so after washing. 
They can be made custom and used to protect your couch, chairs, etc from drools and dirt
 
Choose Natural or Dandelion Twill (much more durable).
