I don't think this is true. Ikea is often included in Sweethome comparisons for which Ikea has products, but the overlap between what Ikea sells (mostly furniture) and the Sweethome reviews (lots of tools, small appliances, kitchen electronics, etc.) is not that great. But Ikea products seem to have been included in all the reviews related to mattresses or bedding, flatware, dishes, pots and pans, etc.: http://thesweethome.com/?s=ikea
