This is a very heavy and sturdy frame.  My project is still in process so I have not yet tried to attach my headboard and footboard.  Right now I have it set up alone on the little feet that came with it and I have to tell you - you can not trust those little feet.  The bed must stay absolutely still or it can become unstable because the feet to do not permanently attach.  They are adjustable so that you can get the bed in a level position.  I am hoping that once I attach my headboard and footboard, the little feet will not be needed.  The frame is sturdy and with a box spring, is plenty of support.
