This underpad makes you want to lie on the carpet and roll around!  It is like walking on a cloud, this memory foam pad is worth the expensive price and much better for a home, your family than the "chip" foam that is available everywhere.  
This product is not readily available in Canada, yes we are behind in variety of many products :-(  , so get this memory foam pad, it is luxurious, clean and well worth the investment for a great carpet that you may have!
