Good idea, but poor workmanship and design.
Provides good support, but cheaply made.  Stiching on piping was unravelling out of the box.  It is a bit of a velcro nightmare to put on and take off correctly.  The tendency is to discconect fasteners in the wrong places.  Mava customer support appears to be nonexistent.  I would not purchase again.
