ive had several sets of them and one pair was just over 40quid, they used to flood ebay with them and sell them auction style, back to the point though, they are a cheap pair of seats! but for the money they are excellent, pretty hard wearing and look th e mutts nuts.
i would reccomend them, only downside i could think of is if you do lots of driving (motorways ect), they get a bit uncomfortable.
