I purchased this under bed rolling storage bin for a guest room. 
It provides much needed, out of the way but easily accessible storage for extra blankets, pillows or guests items. 

The bin arrived on time, without damage and did not require any assembly. 

The quality of the bin is fair for the cost. It rolls easily, the side walls are sturdy and the handles are well attached and allow the user to pull the bin from under the bed easily which boosts  the functionality.
