I have not measured but I am not sure it is really 10 inches, also the top layer feels a bit thin and you can kind of feel the springs I wish it was a bit thicker, my wife has not complaint much about her back so it did help her compared to our old bed. Still decent but not a 5 star bed. Also a bit noisy when moving around you can hear the springs.
Alright mattress
