Stay fit and healthy while you work with Lifespan Treadmill Desks. The Lifespan Treadmill Desk combines our high-quality UpLift Desk with the popular Lifespan Treadmill. Users can easily raise and lower the desk from sitting to standing height with either electric height adjustment or manual height adjustment; a whisper-quiet motor efficiently powers the legs. Significant gains can be made by walking at a relaxing one mile per hour pace. We recommend this treadmill desk to users of all ages and fitness levels.
