LOVE that these have straps that run under the furniture and buckle together.  we live where it's windy and so furniture covers quite often end up blowing loose and off (even when tied to the legs), but the straps underneath prevent this.

Bummer:  one of the straps has torn off from the wind so stronger stitching and reinforcement at the placement site would be good.    And also slightly longer straps for deeper furniture:  it's a stretch to get it connected underneath.
