They're good quality sheets, but definitely not as soft as I was expecting.  I've felt other bamboo sheets that were way softer and these don't compare.  I've washed them twice and they're not any softer after the second wash.  I'm going to make a guess that bamboo sheets are definitely a "pay for what you get" type product.  These aren't the worst sheets in the world, but if there wasn't a cost to return, I would have.
