Folding teak wood chairs. Need TLC. New, replacing these 4 chair would cost $2000 (Or more ... one store lists essentially identical chairs at $950 each but see the link for the lowest price ($450) I found). Perfect winter project for handyperson. Sand them down, replace a few bits of hardware, and rub with teak oil for like new look. Then keep or sell. The first picture shows the 4 chairs. The one on the right was briefly sanded on the seat and arms and rubbed with teak oil (see second (closeup) picture)
