TR1200-DT3 LifeSpan Under Desk Treadmill

The Lifespan TR1200-DT3 is an under desk walking treadmill with a desktop controller. It has been designed from the ground up for whisper quiet operation and its unrivalled build quality ensures long life, durability and trouble free operation.

Suitable for home or work, simply place the Lifepsan TR1200 under your own height adjustable desk and put the DT3 controller onto you desktop.

Do I have the space?

The space currently used by your chair will usually be sufficient to accomodate the TR1200. Measuring 160cm in length and 70cm wide, the walking part of the treadmill will protrude between 80cm to 100cm from the edge of your desk.

Is it easy to walk and work?

Thousands of our customers think so and you soon forget you're walking! Whilst the maximum speed of the treadmill is 4mph (a very brisk walking pace) we find most people walk far more slowly when working. Even at a very gentle pace of 1.2mph you will walk around 4,500 steps per hour.

The phycial and mental health benefits from swapping hours of sitting to a gentle walk can't be overstated. Walking at lower speeds will allow you to work normally without becoming breathless or working up a sweat.
