My original purchase of a 4-leg, commercial standing desk from UPLIFT Desk in 2020 went very well and I have been very happy with their product. They recently released new long feet for their 4-leg desks to enhance the desk's stability. I assumed that there would be a charge for purchasing and shipping this retrofit to my 2020 desk, but SURPRISE!, they shipped me the long feet for my desk at no charge for the parts or shipping! Now my 4-leg desk is even more stable than before at no additional cost to me. I am truly impressed by Uplift's exceptional customer service and great products. THANKS!
