Foam thickness was acceptable, the cover was not much. I certainly wouldn't say it was 1.5 inches...maybe if you really fluffed it up you could call it that. We thought the cover over the top would help provide a barrier and have more breathability but even with it plus my original mattress cover it was still too hot to sleep on. My husband and I both woke up sweaty in the middle of the night. We had to return it.
