Absolute comfort
There is not much to say about this backrest other than it's been an incredible addition to our couch and my only regret is that we only bought one.
While labeled "squish" I was worried the backrest wouldn't be supportive enough, and while I wouldn't recommend an entire Lord of the Rings marthon while using this, it is absolutely firm enough to be comfortable for an evening movie or TV show.
The material in both the pillows & blankets remains unmatched though and is incredible soft. I would absolutely recommend this product to anyone who enjoys a cozy couch and has the disposable income to spare.
