This is not the best memory foam we've owned to date. It doesn't seem to have the same support and comfort levels of previous (non-blue) mattress toppers. In addition, it has a "chemical" odor that seems to really bother my wife, even with a mattress pad and sheets over the pad. Not bad for the price, and still better than the mattress itself ... but, I wouldn't purchase this item again ... I'd go back to the traditional memory foam.
