This slipcover is Not non-slip on leather chairs.  Only one strap going around the back of the chair to hold it in place.  The strap is black elastic, 1.25 inches wide.  It’s one piece in a loop with a fastener attached to adjust the length.  On each end are flat metal hooks to slip through fabric flaps sewn onto the back of the cover.  Nice, it can be laundered without the metal.  Comfortable two ply material with a little filler and nicely constructed.  There are three pockets on each arm, all are 6” deep, middle one is 8.75” wide, all the others are 6” wide. No pockets on reverse.  All edging is finished with double seam binding and the quilting pattern is in 2” squares.  The squares are not stitched but heat sealed perforations. Also note placing anything heavier than a pencil or tissue in a pocket and the weight pulls the cover off, unless you keep both sides balanced.  I’ve added fasteners to secure the arms.  Fit was right on and looks sharp.
