Does not live up to its guarantee!
I work in an office and some days I can be at my desk for 10+ hours.  I bought this cushion because office chair's padding seem to go to heck quick and wanted something better.  I have been using it for a month, and I feel its horrible.  I has totally flattened out in the middle and I feel like I am getting no support what so ever.  Its just not holding up especially for the price and the guarantee they give.  I want to return this item.
