I had the opportunity to use this seating comfort product. I'm on an extended driving holiday and bought a pearl seat to see if it would be more comfortable. It was. I drove 380 miles with only a few short stops and arrived on time. My back felt just as good as when I left. The seat would benefit from something to keep it below the knees. You should always look backwards to see if the seat is dangling behind the door. I can fix it, but I don't have to. The monofilament holding it together seems strong enough that we'll think it through. I only found one broken bead that fell off. By aligning the front edge of the cover with the front edge of the seat, the extended area does not rise as high as it should for optimal comfort, but is still comfortable. A very good product well worth the price.
