Ergonomic Armrest (100-TOK004 Series) I assembled and used this once, but it didn't fit my build or posture, so I'm selling it. I only used it for about 10 minutes. Please check the size in the photos. Includes: 4 bolts + 1 spare Hex wrench Instruction manual Everything is included. Since it's practically new, I'm not considering lowering the price. It will be shipped in the original cardboard box it was sent in. Instant purchase is welcome.
