3 stars, because we can not put that 2

Indeed, the product itself is nothing special and you really had to replace the old cushion.
The real benefits here were sufficiently reasonable price and the fact of not having to move.
We are waiting to see how long this cushion will hold because the sensitive parts (slots for the passage of fastening straps and seams of the PVC cover on the perimeter of the airbag) are not particularly strengthened.
Everything depends on the same resistance of the PVC cover that is especially thick.
So not top quality, but not zero not more ... especially for the price + home delivery.
