This is a very nice rug pad, however I am not so sure it's worth the extra money.  I don't think it makes your rug more spongy or soft.  It does keep the rug from moving, and it's better than the other rug pads that are flat and have holes.  And, it does place the rug higher up.  It's just tough to justify why it is so much more than other rug pads.  Overall I definitely like it, and kept it and happy to have done so.  Just not sure why it is so expensive for a rug pad.

Pros: Rug hasn't moved once since placing it down;  Rug is higher up than it would have been with other rug pads.
Cons: Too Expensive for just a rug pad in my opinion
