Not happy. It is not what I thought. Very disappointing, sorry. I’m disabled! I didn’t realize it was manual operation! I didn’t read clear enough. Also. Had a hard time pulling lever. Now it won’t stay closed. I cannot use chair at all it tipped over with me. Can I trade in for another chair. This one is of no use for me I’m scared to sit in it. Sorry! It sits hard. Not comfortable at all ! ? Adrienne Hansen
