    The shelf was well made and easy to assemble.

    Posted by MARY on 7th Mar 2023

    The 4-tier corner shelf was made very well and, most importantly, it was extremely easy to put together by a single person. Lots of room on the shelving, and it can hold a lot of weight!

    Works perfectly

    Works perfectly with our other shelving units although we did have to order an extra shelf to line them up. At least the shelf is available through the manufacturer.

    This shelf is a very heavy gauge wire & is extremely sturdy.

    Posted by AMcKinley on 23rd Aug 2022

    My only complaint is there is no option to buy it with casters. The hole diameter & threads of the screw in leveling feet are a different size than any shelving unit casters I have found. After a couple weeks of trying to find casters that are compatible with the holes, with no luck, I decided to abandon my search & live with the fact I would not be able to move it easily.

    Extremely durable and adjustable base for uneven flooring made this corner cabinet a great fit for a corner pantry in the garage.
