Ordered for an office area. Used a cordless very slowly, as it can strip bolt heads-but is fast for taking out the bolts, especially the long arm bolts. Used the cordless to begin & hand tighted all bolts with the  provided Allen Wrench(Ladies-use gloves as it helps).Loosely put in all bolts as the fabric covers some predrilled holes-then tighten. Put washers next to the bolt heads-not next to fabric. 
FYI: 1)Blue fabric will show all lint, 2)Legs in headrest behind zipper, 3)Cut off Certification Notice to tighten velcroid fabric, 4)It is short to the ground!
Two people are needed to carry it to the room, but if a 76 year old woman can put it together, put it up - Anyone can do it!  Cannot comment on comfort or durability at this point.
