Hard to tell as I haven’t slept on it but it feels much thicker and is truly memory foam . Much better quality than what I replaced which was a much older version and thinner so I’m sure this will fit the bill. It does have a smell which the instructions said it would for 72 hrs … also said it could take that long to puff up but mine puffed up with in minutes. I will wait to make up the bed until the smell is gone.
