Stinky seat's gotta go

It's been almost 2 weeks since we got this play set to help Mads learn to sit up. The seat smells horribly like plastic glue and unventilated plastic factory. Every time we pick her up from the seat she wreaks of the smell for minutes.

I've washed the seat with my trusty homemade baking soda/vinegar concoction and have tried airing it out. No go. So gotta go. Too bad, it seemed like a great idea for a little while.
