I purchased these sheets because I have pillowtop mattresses and am usually disappointed with the fit of the bottom sheet. These sheets truly are as advertised. The extra deep pocket is ample for my pillowtop without being too big. The elasticized band all around the fitted sheet guarantees that there won't be any "pop-up" corners. The embroidered polka dot adds a splash of color without being "over-the-top". These sheets aren't for your regular mattresses though. The deep pockets would cause excess fabric on shallower models. In this case, the extra pocket statement in the title is actually true.
