Received in a timely fashion, this thing is seriously huge.  My husband measured it and it is actually closer to 17 inches from base to pillow top.  The quilt I got for it was for a California king and it barely covers this mattress from side to side - unable to tuck it in. It is a firmer mattress than I am used to, but I can sleep on concrete - so there's that. The white glove delivery service was nice and included in sale price. Overall pleased and was a great value.  Just a bit bigger than expected - usually it's the other way around.
