The Focal Upright Mobis II Seat is another innovative active seat from Focal Upright, that breaks the unhealthy mold of your traditional chair - adding Movement and Posture like no desk chair can. You don’t sit on the Mobis Seat - you lean into it, and move with it... and the results are invigorating!The Mobis II functions much like the famed Locus Seat, but without the anti-fatigue mat and foot rest. This makes the Mobis a more mobil option, or a great option for areas where space might be limited (retail counters, reception desks, meeting rooms, etc.).When compared to the Pivot Seat, the Mobis can be used as a much more stable option - offering more support, but less movement.
