According to my friend....when she opened the space bag, which was in transit for 6 days....it plumped back up right away. I had told her to lay it out on her bed as son as she got it out of the box/bag. She said it looked great.
My friend lives in Nebraska on a cattle ranch.....true God's country. They only get mail Monday/Wednesday & Friday

.
Yeah we had a ball trying to get it all figured out & in the bag/box. I figured others may want to know how to do this, so they could save on shipping costs.
