Hubby and I put this together over the course of a day during our baby's naps so I dont know exactly how long it took but we did predrill all the pilot holes with a power drill prior to assembly, which made it go faster and was easier on our hands when using a handheld screwdriver. We are completely satisfied with the quality of this piece and would purchase again if we needed more storage in the future. Make sure you anchor it to the wall for added stability, especially with kiddos! We have the one with and without the drawer (due to product availability and requiring two for our storage needs) so you can see the side-by-side comparison in the pictures. Definitely recommend this (or similar) product for basic storage.
