Sturdy and easy to assemble.

This unit is the most sturdy I have put together in many years. I have recently moved and have put together many, many items like this recently. It is really sturdy and looks great. It uses actual screws and nails. The directions were easy to understand and follow. This was a great purchase!

Sturdy Storage

I love these organizers. Definitely a great investment. I purchased 2 for my craft shop. They are very sturdy and looks great overall. They took my son less than 1hr each to assemble. Id also like to add, b4 I recruited my son I attempted the 1st one and mess the board up.. I reached out to the company and they replaced the damaged parts.. 10/10

it was incredibly easy to put together. it would feel more sturdy if i connected it to the wall but honestly holds up fine since i dont pull on it. one of the cheaper storage unit options so feel the price is comparable though maybe slightly over priced (isnt everything though?)
