Bought these 2 mattresses (with bed bases also from Wayfair) for spare beds for guests.  They were delivered `rolled' and came with full instructions as to `how to undo'.  I `undid' as instructed and felt a little sceptical that they would settle but they did! I have had occasion to have to sleep on them myself and found them to be extremely comfortable.  No complaints from guests or me so very happy!
