To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These have been amazing. Initially, my husband and I were looking for something we could use for back support on our couch. I wasn't thinking individual cushions for us, but I'm glad I found these. They've helped SO much sitting at our dining room table on the days we're working from home. I've found that it does help my posture, too. We do also use them when we're sitting on the couch, and it's made a huge difference there as well. I'm very, very happy with this purchase!
I bought four backrest cushions from Amazon. This is the best of the three less expensive cushions. I keep this cushion on my computer chair. The backrest aligns my spine and cradles my back to keep me sitting upright. I've read the reviews complaining about the elastic strap. I would have paid more to get a strap that clicks together and can be snugged tight.
