I realize products periodically rise in price, but I am surprised to see the Tension Adj. by Strap back upholstery jump from $175 on the January order form to $300 on the current (July) order form.

Does anyone know if there was a change to the upholstery?

The tension adj. by strap seat upholstery has not changed in price, in fact it is the same price as when I ordered in '09, $150.
