IMPOSSIBLE to mount
I purchased directly from purple. Fantastic lumbar support ruined by a it’s mounting solution. The single strap makes it IMPOSSIBLE to mount to any chair in the proper position. It needs a top and bottom strap, or better yet, a tightly woven wide elastic band to slip over a chair back. As it is, the single strap is too long, does not stay tight whatsoever, and basically just dangles the back support in an unusable spot. You can place it where you need it, but the second you make a micro adjustment, it falls out of place. Frustrating, and now I have to continue my search.
