The Series 3 is our entry level frame which is perfect for a small or home office and has comes with a 3-year warranty. The electronics and motors are 100% Chinese as is the frame manufacture. Aesthetically the frame has a different, less European look with slightly more gloss to the powder coat. Functionally it is largely the same as a Series 2 desk however it is in the finish and refinement that the cost difference lies.
The Series 2 is a more commercial desk frame and has a better quality of metal work, powder coating and upgraded electrics and comes with a 5-year warranty. The drives and controls are made by Ti-Motion in Taiwan and the powder coating is full matt. The desk has a long pedigree and has longevity rates based on a large number of units sold into the market.
