Premium Sacro-Ease Back Support

We use these on our couch to lend support to squishy cushions. Really helps.

It's very good.

Great for back, but not perfect.

Although it is great for my back, I do wish the base was a little longer to be about as long as my seat in my car and the back a bit taller to support my upper back also. I find my upper back not having support so leaning back is a bit awkward… overall feels like a quality product and it does help my lower back, just wish base was longer and back was taller.
