...if you count the peaks of the egg crate pattern. The topper arrived promptly and in good condition. When we opened the saran wrap that it is shipped in, it pretty quickly assumed its normal size and shape. While you can tell that the foam that is there is of a high quality (and density) there isn't quite as much of it as I'd expected. About half of the 3 inch thickness is taken up with egg crate pattern, leaving only about an inch and a half of solid foam. This being said, my parents (for whom it was a Xmas gift) have had no complaints, so I guess there's no harm done.
