I bought the 3" pad from Mark's 1/2 Price bedding about a month ago. He sells on E-bay or direct for the same price (no advantage to going through e-bay, except that e-bay takes a cut of Mark's profit). I spoke to Mark directly and he was very helpful, answering questions about what I should buy (Tel # is 407-282-6592 - Call and ask for his URL, I can't remember it). I got the 3" pad, two pillows and a travel pillow. So far, I find it to be comfortable, but it takes a "little getting used to." The pad retains heat, so I only use a topsheet now, no comforter (yet - still summer here). I don't move much on it, either. All in all, I am happy, and I have a 60 day guarantee. I would go for it.

<<<I don't know about the mattress but the topper is usually found on @bay. Mark's 1/2 price bedding and another store. If you already have a decent mattress the topper is all you'll need. I think another store's name is Memory Foam Superstore. They also have a 4" thick model.[/quote]>>>
