You don't need a box spring and the frame I bought was a frame that can be used as a box spring because of it's shape. Packaging was easy as unpacking and taking it out the plastic covering to let it unroll and fill up with air. It was to size in minutes. On the frame/box spring it is not as cloud soft but better as for those who want soft it is, for those who want firm it is as well. It's perfect and I am in love. For the price, the quality, the ease of comfort and more I will buy every 5 years just cause I can afford it. It You do not need the 50bucks warranty.
