Super easy to assemble.  We have 12 cushions to store and though the box is fairly large, we are unable to get the last one in.  Our lanai furniture is big, so cushions are pretty big also.  Will probably buy a second box in a smaller size as we have an additional six chair cushions that need to be stored.  That should solve the “one left over” problem.  Box looks great, is well made and we are totally delighted with it!
