MLB Mavrik Stadium Cushions

Is this the same brand/seat cushion? Description says measurements are 14" x 14" x 1".

Can you confirm if this is 1" or 2" cushion? And what material this is made out of?

We just added this to the features:

The material is 420 denier polyester and the dims are 14” (L) x 14” (W) x 1” (H).
