The first version of this pillow which was created in 2012 was a gift for my nephews. As a mother, I noticed how comfortable they were sleeping and how well they slept because of it. I wanted to make more pillows like the one we had and I found the perfect material: hollow polyester fiber from polyester blend fabric, which is similar to what polyester t-shirts are made with. The softness of this fabric allowed me to put many layers on top of each other without making it hard for them to breath inside their pillow.
