Although the sheets are nice and soft as bamboo promises, the workmanship of the stitching and the quality of the elastic is poor.  there were lots of loose threads that I had to pull out and a lot of longer threads that were still stitched and attached so I had to "trim" the sheets.  The elastic does not old around the mattress.  By the time morning arrives, all 4 corners have popped up and off the mattress.  I'll probably sell these in a garage sale.
