We used a single arm mount that was purchased from Overstock.com for $25. No extra reinforcement was needed. But we used shorter screws than what was supplied with the mount. The TV stays completely in the recessed cabinet when pushed in, and comes out a few inches to change the DVDs or to just swivel the TV into a better viewing position while sitting on the couch.
