It has a good amount of storage but I wouldnt suggest using it for a seat. The lid/ top is the most sturdy part but its hard to get it on straight sometimes. As a consequence, I sat on it not knowing it was slightly misaligned and it ripped 2 corners. I'm only 140lbs and it says up to 250 but I wouldn't trust it. Cheap materials but it looks nice at the end of my bed if I hide the 2 torn corners. 
Expected better quality
Wouldn't purchase again.
