These are beautiful Egyptian cotton sheets! They are soft after only one wash (I always wash new sheets before I use them). The only thing that I don't like about them is how deep they are. We have the Pro-Adapt Hybrid which is one of the deepest mattresses. We are trading out to the regular Pro-Adapt mattress which is 1" less deep. I think they will work especially since the new mattress is lighter weight. I would but them again!
