I use my iPad with this case constantly and it has yet to fall apart. It's just supposed to rotate, making it easier when watching videos or shows. So to answer your question it is only one piece not two.
No its all together in one piece. Set the ipad in the case & the folding cover goes over it & the band holds it close. The apple shows in the back as pictured. Its like a book almost then it opens & you turn to position it on the little ridges to stand it up, hopes this help Samantha
