Larger than I thought it would be.  Best you have two people to assemble.  BUT I was able to do it myself using pillows and other furniture as leverage to "hold" pieces as I put it together.  Make sure you put the large handle on the "lid" piece first to keep it from rolling back and out of place before you attach it at the ends.  I learned this the hard way.  Now if we only would get some cooler weather.  I've used it twice and have been very pleased.
