Here's one with my little girl Lacie. It's just a normal pet bed.
There is a Foam store in my area that is supposed to have the pet beds in the memory foam for an awesome price. I'm going to check it out when it's time to replace the one she has now.
I discovered a long time ago that she would not constantly seek the warmth of my lap if I put a heating pad in it. When I am home, it's on but when I'm gone, she goes into her crate and at night, she sleeps with me.
