Removing cushion from Aldi Bikemate Boodie seat I would like to remove the cushion from my Aldi Bikemate Boodie seat - it is unpleasant after spending the winter in a damp shed. There is only so much cleaning I can do while it's on and I don't want to expose the plastic shell to cleaning chemicals.

(Edit: Daniel R Hicks pointed out it looks like "Polisport Bubbly Maxi" and it is exactly the same seat, and it turns out so is "Raleigh Avenir" and others - they even keep the "boodie" embossed on the cushion. Clearly it's all licensing etc.)

I contacted Teknihall using the info on the product information plate - but I'm not sure if Teknihall are the original licensor or one of the many licensees. Anyway, they said they would look into this, they may still get back to me and I will update this question if they do.

The problem is that the cushion is held in place by a clamp/jaw which I highlighted in photos 5 and 10. It seems like it should be possible to slip the jaw off. I gave it a go and it didn't move. I'm conscious I will brake/strain the "tongue" that the buckle sits on if put any more force on it. I can see how there might an element of rotation involved in slipping it on and off. I can't see any catches/levers I would need to prize/lift.

The question is: has anyone removed the cushion on a seat like mine or similar? The tongue that holds the buckle is clearly a safety critical part so I don't want to mess with it unless I am happy my actions are safe.

First, for what it's worth, this is probably a Polisport brand seat, possibly the "Bubbly Maxi" style.  Contacting Polisport (however one might do that) would be more likely to be productive than talking to Aldi.

Unfortunately, I can't make much sense of the pictures.
