These chairs are unpredictable and can be dangerous. When you sit down on the opened chase lounge, the back immediately flips up. Attempting to push the chair back down can be hazardous. Fifteen minutes ago, I sat in the chair, the back flipped up, I reached back to try to adjust the angle of the chair back and as I attempted to move the chair-back height adjuster my pointer finger got crushed between the adjuster and a cross bar. My finger is dented and getting black and blue. I had to have my wife push the chair back forward to release my finger. If I had been alone I do not know how I would have ever released myself from the chair. No at all happy with these chairs. I have never owned a chase lounge that did this. I have owned chairs that cost half what these chairs cost and have never experienced such a problem.
