I got this frame foundation for a guest room that is not often used.  I'm glad it is not used often because I'm not overly fond of this.  It is virtually impossible to put a skirt on top of it, then try and lay down the mattress.  The skirt slides everywhere. Even with the mattress on top, it continues to slide. I finally put an inexpensive foam pad on the frame, then the skirt so it would have something to adhere to.  That helps.  I will most likely replace this with a traditional frame and box spring.
