Delivery of this King Mattress was almost unbelievable. It was sealed up and packaged like a expandable sponge. Remember the one that you put in water to grow to acutal size. Of course, NO water needed!!! When air hit the mattress, it grew into a 14-inch King Size dream come true. We ordered a medium firmness and I think all should know that it is on the firm side of medium. Like a good pair of shoes; each day this mattress gets better and better. To sum it up: this mattress was delivered to my door without one issue and it is the answer to my slumber solution.... You will not regret this purchase for Great Offer Stock.com.
