I got this walker for my mother-in-law. There is absolutely nothing wrong with the walker...just the person (me) who tested it out without reading the instructions first. I know my mother-in-law and know she will try to sit and scoot backwards in the walker. So, I sat down and proceeded to scoot. All went well on the hard floor but on the carpet I went over backwards. I thought, "Well, that must have been a freak accident." So I got back up and did it again. :-) My wife then read the instructions for me and said, "The walker should not be used to transport or move around while seated."
So, fantastic walker. Read all the instructions before use. Don't lean back in the walker because it will over-center and flip over backwards.
Great product. Use as intended or you will go for an unintended ride.
