INTERESTING product!
INTERESTING!  Firm when you sit down, does not feel like a down pillow (for example).  However, while sitting and shifting weight, the cells collapse and still cradle!  We did try the egg test... husband could not break it, even when sitting and bouncing on it!  Egg only broke when it bounced and hit the table from a the height of the cushion!  Would recommend trying if you are interested in their products or you get sore sitting for long periods of time!
