We have had this bed set up for several months and have not had one issue. We own an eastern king, tempurpedic mattress and it fits great. My husband put it together himself and had no issues at all. The slats show just sightly on the sides but it's not a big deal at all. Side note, if you put a cal king, which is a few inches narrow then an eastern, it might show more. We actually have our box spring plus mattress sitting on top of  the existing slats (just for extra support) and although its 2-4 inches taller than the foot board, it works fine especially when the bed is made, you can't tell at all.  The color is exactly as you see it in pictures and the fabric is good quality. No issues with fraying or lint build up.
