WOW what an easy to set up foundation- just unfold, unfold the legs attach the support arms to the correct area with the hardware included--no tools needed, great product seems sturdy enough to last some time to come. My 
Mattress did slide or move around on this foundation. I love the extra storage space underneath; that's what I needed. Wonderful invention. After sleeping on this I find the foundation moves on my carpeted floor. I am applauding the shipper and handlers of this item as the box was totally intact and the foundation arrived in perfect condition-no bends scratches or dents on the foundation itself.  I was relieved that my item arrived in perfect condition. Thank you.
