The mattress was delivered earlier than scheduled which was great.   However; I almost didn’t give the mattress 5 stars because I noticed it didn’t inflate past 8 inches and I bought the 10 inch size.  I went online and learned it’s common for the bed in a box foam mattresses to be compacted in shipment.  It was suggested to put the mattress on the floor and roll on it and put the heat on in the room.  It worked.   I slept on the mattress in the guest room to check out the comfort level and was pleasantly surprised.  I will be buying the same one in queen sized.
