The intention of this device is to raise the height of (part of) a normal-height desk to be high enough to use as a standing desk. I used this for a few weeks and then decided to buy an actual standing desk, so I no longer need this. It is in excellent condition. It weighs about 15KG so you will need a car to transport it.
My schedule is unpredictable but reasonably flexible at the moment, so let me know what days/times suit you for collection and we can work it out.
