This product is really well engineered for the sake of assembling it at home (after having all 275 lbs of it delivered). I had no issues with things like holes, boards or panels not lining up or the island being unstable after it was mounted. The cabinet doors shut perfectly. I'm very pleased at the quality of this product. The best part was that the assembly directions were excellent and I was able to assemble it and the chairs in just about two hours. I'd say you definitely could use a second person for setting the counter on top of the frame. However, it is not impossible to do it solo.
