I have no clue what sort of beds everyone is using! I've added a 3inch mattress topper and a fitted mattress pad...and the sheets STILL FIT! They're not the softest, but definitely not bad for the price! Overstock has been wonderful with giving discounts/shipping and having it all delivered within the time span. The quality is great and if you don't like it..RETURN IT! They'll give you the shipping label. But yes, the sheets fit well and there is an elastic that is just like all my other sheets including the ones I've spent $50 plus on.
