I think the original one they started with just called 'The Body Pillow' is the best

They have stacks of different ones now, but the original one is fantastic... DH & I still fight over it now & Luke is 10yrs old

We bought ours from Myer, but I think you can get them from most manchester shops.. there are cheaper versions, but ours was about $39.95...

I've found the pillow cases for them are more expensive than the actual pillow

Mine is still in fantastic condition 10 yrs on.. and it still gets good usage
