Bought this for my husband for the garage. It literally took maybe 10 minutes to assemble! No tools required. And this shelf can hold a lot of weight! He was able to pack several heavy tools and items on this shelf with no issue or worry that the shelves will bend over time. Would definitely recommend. It’s a little more expensive than some of the other units we looked at, but this will never need to be replaced. Definitely worth the extra money. We plan to buy several more to store our other items!
