Review title: Great support, not meant for all chairs.
Product review: Love this back cushion! Fits perfectly on my office chair and makes working much more comfortable. I tried using it on the couch but the strap didn't fit around the couch cushion and without this support it slides down every time. I'd imagine if you had a very poofy office chair back the strap wouldn't fit around it so I'd take that into account before ordering.
