I wavered between giving it 3 or 4 stars but considering the budget price, and with the caveat that I've had it for less than a week, I'm giving it 4.  The frame itself was not difficult to assemble and seems sturdy enough; inserting the metal slats into the frame was a little more of a chore and they rattled around bit even with the plastic "locking" pins until the mattress went on.  Having storage space under the bed without having to jump/climb on the bed makes me with I'd traded box springs for platform design years ago.
