This is more about the manufacturer. Chair legs do not lock. The foam cushions are total ***, an ounce of weight compresses them fully. Material t6o rest your face on is rough. I am only 5'-7" tall; when lying down my outer back rest on the tubular framework on both sides and is not at all comfortable. Item does not fold up compactly. Width dimension is totally false. It is a $40 to 50 dollar item that cost $175.00. Toatl *** and a scam. Item was not designed correctly, used inferior materials and is being sold for 3 to 4 times its worth.
