Within 24 hours, the mattress expanded to roughly 13 - 14" depending on how it is measured.  I said it is around 13.5" which is good enough for me.  I lay on it briefly and it felt comfortable and but not too soft where my body would sink in too deep.  I weighted 175 lbs.

It looks exactly as the picture being shown on the website.  Only time will tell if this is a good purchase but so far I was/am pleased with the purchase.
