If you have alien like long arms and hands the size of Barbie, this is fairly easy to assemble. It's a great bench, our second one. The first one has held up so well over 7 years we decided to buy another. However, be prepared for circus act like contortions and marital counseling if you assemble with a spouse. Everything is machined well, holes all line up, but the location of the screws can be really difficult to reach and start/tighten in some areas.

This add on cabinet makes a great addition to an already great cabinet. Looks good and adds more space to make it a supersized storage cabinet. Same great quality and features as for main cabinet. Highly recommend!

I just love the whole set up in my garage. A small panel was damage and they were real helpful with replacing it. Customer service was great and fast. I'm a future customer from now on. Thank you everybody.

This was a great addition to the storage cabinet. The assembly was very easy to complete. If you have the extra height, it adds much more storage space.

I absolutely love my Seville Ultra HD garage cabinets! So much storage and now with this additional space on top I am able to get all of my stuff put away organized! Love it!

Delivered earlier than predicted, no damage. Added substantial extra space to other cabinet. Would like to have had a way to put a shelf in this extension.

Damaged order, not faulting Sams but 1 cabinet was unusable after unpacking it. Although still waiting from Sams for directions after opening a claim. In all fairness I have purchased 14 cabinets with only one arriving damaged.

Probably the worst thing you've ever put together! unable to insert screws where needed . Do yourself a favor and don't waste your money. If I couldn't modify it would have thrown this on the doorstep and got my money back! Don't do it! Lol! TRASH

While not perfect, this unit was so much better than a recently purchased big box store cabinet, it is a five-star in comparison. The packing was superior to my other cabinet. I couldn't believe how much stiff cardboard packing was included. Every piece inside the box was protected. It helped, too, that the shipper did a great job as there was no outside damage. I believe Fed-Ex was the shipper. The damage that did occur apparently was during manufacture. If there was no exterior damage to the box containing the shelves, then how did two corners get deformed as if they were dropped during packaging? I was able to use a screwdriver and needle-nose pliers to open a slot for the shelf supports to fit. You can't see the damage and it works fine but I can't help but believe it was knowingly packaged after the damage occurred. The structure of the cabinet is awesome. Braces on the corners, over 150 screws, reinforced shelves, and very detailed and easy to understand assembly instructions set this cabinet apart. I was not familiar with the Seville brand. It was recommended by a reviewer for another brand of cabinet. I am very satisfied with it. I highly recommend this cabinet.

I continue to add to my workspace in the garage. I now have about 8 to 9 cabinets and workstations… Makes the garage look very clean and crisp. The functionality of these cabinets are amazing. The assembly is by far one of the easiest I've ever done. I will continue to use and refer out to my friends and family.
