Fairly easy assembly, I am handy and took me from start to finish, including adding the decals and staging it with all the pots pans and food (as it was a gift from Santa) 2 hours.
One piece did not fit properly, will have to call to get a new one. but overall it is a great kitchen and grill set. My 3 1/2 year old son loves it plays in it for hours at a time. I would recommend a small crate of some kind to collect all the accessories - the storage space gets crowded for little ones to put it all back neatly. Cleanup time is much easier for my little one with a small crate.
