Had to buy hardware to replace too short screws. Holes drilled incorrectly under arm attachment. Can now see big hole under arm where Two holes had been drilled instead of one. Arm of one chair stained improperly so that the entire arm from back to floor has 1 1/2 inch red streak thru the middle. Poor arm leg design causes back legs to lift from the floor when one arises. It is possible that older person trying to arise and if chair is on a slippery floor it could actually tip all the way forward with the person either on their knees or flat on their face on the floor. I guess I am stuck since I have had to use these chairs. Do wish the company could help me out of this dilemma somehow.
