Bengal 1 Person Chair Hammock

I purchased this product for my special needs daughter. She is 13 and weighs about 40 lbs. My other daughter who is 18 and weighs 110 lbs sat in the chair and it broke at the top. The entire locking mechanism with springs, ball bearings, and main bolt came down. Due to the swings design, the main bolt shot straight down as if on the end of a rubber band striking my daughter in the head. I expect it felt like being clobbered in the head with a hammer. A major bruise bump instantly appeared and she had trouble regaining her thoughts for the next hour. Needless to say, I am upset. Upset that Morgan was hurt...but really upset that my special needs daughter who is very fragile could have been killed had she been hit in the head like that. BUYER BEWARE. I can provide pictures of the broken pieces if anyone is interested.
