Abstract: An anchor for rocking furniture including left and right flat-bottomed elements longer than wider, with width less than half the spacing between rockers of rocking furniture to be anchored. A forward element releaseably impedes the flat-bottomed elements from separating by more than the rocker width at a first point forward of a back leg of the furniture plus a gap substantially less that the width of the wider flat-bottomed element at the first point. The forward element is vertically positioned between flat-bottomed elements above the height of the rocker at the first point. A rearward element impedes flat-bottom elements from separating by more than the rocker width at a second point rearward of the back leg plus a gap substantially less that the width of the wider flat-bottomed element at the second point. The rearward element is vertically positioned between the flat-bottomed elements below the rocker at the second point.
