ezseattleThey have an option on their website for a dual, side by side setup. Unfortunately, I don't see anything on monitor specs/restrictions. I have two 34" ultra-wide Dells stacked at the moment and would be willing to go back to side by side.
ezseattleContact the manufacturer (Uncaged Ergonomics) and they can hook you up with a dual monitor mount. You can use either a single or dual monitor mount with this product (Massdrop is only carrying the single monitor mount) and it's easy to interchange them.
