National is a great place to Purchase a Mattress, Huge, Great selection. We were Able to purchase a really nice mattress at a very good price. The people at the warehouse were knowledgeable and very helpful. They deserve 5 Stars The Delivery people were just awful. Uncommunicative, Unhelpful, refused to help. We paid for it to be brought to our apartment, they did but put in the room on its side and wrong way around and refused to help make it right. Then the removal was a challenge for them to put it in the removal area at our building. They turned a great purchasing experience, into a really miserable time for two 80 year olds.
