. I was very pleased right from the start because I was able to compare it with another cushion from a different manufacturer. This product was $20.00 less than the first one I had used and yet it DID NOT squash down completely the first time I sat on it. Yes, I flattened the more expensive product flatter than a pancake the first time I sat on it. This one is still in good shape and I would say that this product is truly 100% pure memory foam. Very much worth the cost.
