Query: Not reliable product

These chairs do not last. Within one year of purchase, one chair snapped along the seat line. The construction of the chairs was sloppy, with connections that were constantly loosening, and required never ending adjustment. Luckily, when the one chair broke, no one was injured. The chairs were certainly not worth the price that was paid for the set. We do not trust the other chair at all, so the whole set is wasted money.
