This is my Smith Brothers recliner in the living ...

This is my Smith Brothers recliner in the living room, with its leg amputated. The "lifetime guarantee" on the frame lasted less than two years. The lug or insert in the bottom of the frame that the leg screws into is defective. They are telling me that it is not part of the frame. It is an accessory or something and is not covered under the guarantee. They sent me a different part and told me to fix the chair myself. However, I cannot get the defective part out of the hole without a special drill. I am not buying any more Smith Brothers furniture. They should stick to cough drops.
