Super easy to assemble, just slide the side-arms which have the feet, onto the main body. The sofa folds flat by pressing it closed like a clam and then it releases flat. 
The color is a luscious ivory. The only reason I graded it as 4-star is that the multi-cushion style feels alittle lumpy compared to a normal bench-style seat. I am fine with it buy my husband who is larger says he feels he might roll off when he lies down on it. (When it's in the flat position of course that's not a problem.)
