BackShape comes with a high quality woven polypropylene strap,
adjustable with a buckle. It is wide enough not to twist, and unbreakable in normal use.
The strap attaches either horizontally, to suit office chairs, or vertically, to suit vehicle seats. It uses hook-and-loop fastener so you simply peel off protective strips and press on the strap, to suit your application.
If you wish, you can peel off all the protective strips and let the hook
strips on the back of the cover cling to the seat fabric. On many fabric
seats this grips so well that you do not need to use the straps (note that repeated removal will affect the seat fabric with a
plucking action that eventually gives it a fluffy appearance).
The flexibility of the system allows it to be fitted securely to most seats.
