It’s taken me 26 years of trying to wear my old Backfriend out and it’s still in extremely good condition.
I originally our purchased the double padded version, but have now decided to treat myself and get a single padded one just for in the car.

I've had my Backfriend for over 17 years - it's marvellous for making sure my back doesn't hurt. I use it for driving in cars other than my own - so it's come on holiday many times - including a 3,000 mile road trip round America (I separated the 2 parts before I packed it in my suitcase). Have had to replace the hinges a couple of times as it gets folded and unfolded quite a lot, but it's a quick job. I couldn't be without it.
