Unusable. Very disappointed.

Extremely disappointed by this product I was looking forward to! First of all it is too full and I end up with a "pudding" not very hard to modulate and very uncomfortable (but that can be fixed by removing some balls, you might say, at this price, it I can imagine to use sns having to reroucher). The most annoying rest the horrible chemical smell polystyrene that emerges! A month later, despite its ventilation and washing attempts, it remains persistent and gives me nausea and headaches for the whole family! I can not imagine the day I approach a baby!
In short unusable cushion ...
