ORIGAMI Refurbished 5 Tier Rack w/Wheels - White

I didn't have any trouble with assembly except for the locking mechanism for the shelving system ( as others have commented). I solved this by getting a heavy coffee table book to place on the shelf, while pushing down on the book to elevate the lock into place. This provided the leverage needed without getting a helper. For reference I am a partially handicapped senior with arthritis...so this project will be easier for young folk. Since I have the larger units, I can say that this will not be useful for heavy items like my other origami shelves that are hefty and larger. However, I can see this working for a laundry room, office files and knick knacks, or as a bakers rack. Overall, I am pleased and didn't have any damage discovered while unpacking, or during assembly of the wheels. Quite an easy project after my last furniture assembly project last week that was very difficult. My shelf unit is going in the laundry room for my containers of powdered laundry soap, cleaning supplies and towels. I wouldn't use it for garage items or canned goods in a pantry however. Just my two cents. 🤔 I do have the 5 shelf origami system for a food pantry in a spare closet that I am extremely pleased with.
