I received a motorized sit/stand desk today for my kids to use in the family room. I assembled the whole thing this afternoon, which was not too hard but took about an hour. Once it was done, I discovered that the left side would not lift. It was a frustrating way to end up. I emailed product support and hope to get some kind of answer. I’m afraid that, no matter what, I’m going to have to disassemble the whole thing to fix it. That will be a pain.
