The metal is a bit weak and will bend if too much force is suddenly applied. Two of the post ends had to be bent back into a round shape in order for the end caps to fit properly. However, once assembled with mattress and box spring in place I have not had issues with the frame bending or warping. I hope this continues to be the case. I have been using this product for about one month. Sometimes the pillows slip through the space in the middle of the headrest when lounging, and I will probably buy a body pillow to help bolster the others from behind.  I think most of the reviews I read are fair, and those who read them will have the proper expectations for the product.
