We love this mattress so far in regards to the comfort aspect. It is extra firm but not hard and unyielding. However it makes a creaking groaning type sound as you get in and out of it. So much so that it will wake my wife up at times. The delivery guy said that it has to have a break in period to work that out of it. He also said the reason you might not hear it in the showroom is because it has been demo-ed by so many people that its all worked out. But we ordered it online without going into the showroom. (Our Bad) Well we will find out.
