Oh, not at all as far as volume of actual foam goes. They also ship theirs in a large cardboard box that is about 28 x 28 x 28 so there is lots of room for foam. I shipped his in a wooden crate that is 21 x 23 x 13 without a single molecule of air space that is not occupied by foam or Atlas parts. There is literally 6 cans of spray foam in that box with the Atlas, all the necessary bits, and 2 quarts of the supplied gear oil. We had to make room for everything by getting rid of all the plastic bags it came in except for the instructions, we put those in a plastic bag otherwise that would have just been mean.
