No little L shaped screw included so definitely have at least a screwdriver or even better an drill! Looks great, feels great. Firm but comfortable. Enough room for me and my boyfriend to sit on comfortably. 4 stars because some of the pre determined holes underneath weren’t prepped or lined up correctly and some were (not sure why). And it made a cracking noise when my boyfriend sat down too fast (to be fair, he is 6’6” and 280)
