A mallet or hammer would assist in firmly locking the cross braces into the vertical frame, but not necessary. If you read the directions once and then think, you will be rewarded with a successful effort and a great sturdy product.

[This review was collected as part of a promotion.] Exactly what was needed for the task. I had purchased them before and knew that was the best choice.

Particle board is a bit thin so I expect will be warping in a few years but was easy to put together and great for organizing. Best with two people and need a rubber mallet.

Did not include all parts specified in the instructions. The four "post couplers" are missing. Cannot proceed. SMH. Packaging insufficient in that the boxes got scraped and torn, some metal beams inside got scratched.

I like the shelves but the edges of the boards were broken and there are no cuplets (I think thats what they are called) to hold the posts together. It isn't as sturdy without them.

Large, strong. Just a little hard to set up due to the flimsiness of joints. And would prefer a waterproof material or coating for the unfinished plywood shelves.

God deal. But a bit flimsy. Particle board shelves and really thin brackets. Level 1-3 not problem. Level 4-5 didn't happen. Maybe consider a set with a solid vertical level to ease things.

Beware that the particle board is thin but it's also surprisingly strong. You may want the wider shelves though. The metal is thinned out too and is a bit wobbly but still will hold your stuff. You just have to be patient putting it together.

These shelves are HEAVY DUTY. I love them!! They are very large and couldn't fit through our door frames, so we had to take them apart, bring them to the room we wanted, and reassemble them. They are 10/10! They hold 12 big tubs for storage.

Ordered two but returned one. It was a nightmare to put together. I had ordered the 36” size previously and it had post brackets to support the upright posts, a much better design. Don't recommend the 48” until they improve.
