Is it just me or are replacement high chair covers ridiculously expensive?

[3xyummymummy]

The cover needs replacing on our cossato aurora high chair and they want almost £30 for a replacment seat cover! I thought this was ridiculously expensive but then looked into other covers and the chicco ones are about that much too, if not more! Is it just me or is this a stupid amount of money to charge for an additional piece to a high chair I've already bought, especially taking into account the whole landfill thing, I could get a cheap high chair for less? ( we are on child 3 and not planning on having more). Was wondering about bringing it up with Cossato but wanted to check general consensus first.
Thanks

you can buy the antilop highchair from ikea for half that price. it hoses wipes down clean.

Def get the Antilop - if you take the legs off you can even put it in the dishwasher. Easy to take anywhere too

Thanks both of you, looks like I might be making a trip to Ikea!
