The bean bag mattress that we purchased for my wife was worn out and she was laying almost on the floor so it needed to be replaced.  I was looking for this item for some time an this was the only vendor that I was able to find it.  She has poor circulation in her legs and has to lay with her feet above her heart to get the impurities out of her legs and this does the trick.  Very hapy with purchase

Pros: tThe previousn mattress was not refillable and this has double zippers be able to add or replacve the fill.
Cons: none
