Just received these chairs 3 days ahead of schedule. Took me a few minutes to figure out how to lock the bottom feet, but once I did chair was sturdy. Lots of plastic as mentioned in other reviews. Only issue I have is the specs state that these chairs FULLY RECLINE FLAT and the DO NOT!! My back was still arched when lying prone. Only way to resolve that was to scoot down and put my head just above the arms which made my feet hang off the end of the chair. Pics attached show chair in fully reclined position and close up showing arm in fully reclined position. When lying on my back chair is perfect for me!
