This is a compact functional table that fits well in our craft room.  However, assembling it was very complex (2 people, extra tools, about 5 hours) Several of the hardware pieces (lock nuts?) were made of a plasticized metal that sometimes broke when lightly tightened as directed...   I'm sure the manufacturer knows about this problem as there were 2 extra of these pieces included.  Despite the extras we ended up short one but luckily in the middle of the table where it wasn't as essential.  The table feels sturdy enough for a small sewing machine but it might be top-heavy with anything over 15 pounds which is likely why they include a 'wall-brace' option, minus the castors.  I wouldn't have it around young children who might climb up or pull on it.
