Ergo Desktop Kangaroo Sit/Stand. Perfect set-up for a home office (or workplace); give yourself a break from sitting all day to enhance your productivity. This is, originally, the Hybrid model but also includes the additional hardware to convert it to the version that can accommodate dual monitors. All sit/stand hardware is included in the sale; the unit is a complete set-up including the stabilizer leg and will, also, include an ErgoTron anti-fatigue mat for comfortably standing in front of the sit/stand. The mat is 36” x 24”. The desk/keyboard surface is 28" wide by (max) 24" depth. The Hybrid works well if using just a laptop with a single monitor; I currently use it with a laptop and dual monitors (as pictured). The 2 monitors are NOT included in the sale of the sit/stand desk. In the pictures showing dual monitor set-up, both of the monitors are 24” and are mounted on VESA brackets (has 75x75mm and 100x100mm mounting holes). These mounting bolts are included, as well. There may be room to accommodate slightly larger monitors for a dual monitor set-up. Note: I included a few pictures that I found of the Hybrid set-up (last pictures posted). All pieces are in good/very good condition. If you have further questions, call/text Scott at THreeh-oohh-3-SeavEn-zero-9-0-7-ninnne-ate.
