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!

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?)

Love Mainstays as a brand — affordable and always stylish, fits my aesthetic perfectly. This cube shelf is no exception. I love that you can customize with different colored bins to personalize it exactly how you want. Great value and looks great in the room.
