I don't know if it was this manufacturer that you mention or not, but I purchased a set of leather seats on eBay five years back that looked just like the picture. They were $200 at the time and purchased from a US based company but were delivered from China. While I was able to make them fit, it required lots of extra fill padding and quite a bit of work to make them fit and look decent They were made from heavy leather but the fit was nothing like Mr Mikes seats. If you use these covers be prepared to buy a couple of bags of pillow fill (available at Walmart) to take up the loose fit that they will have. Mr Mikes leather seats are expensive but they fit perfect.
