Loving my lowdesk, been using it for about 8 months now.
I purchased the frame from Lowdesk and the table top (48in) from somewhere more local to me - so, obviously the table top didn't have the right pre-drilled holes and I had to drill my own. AND, despite this and my limited furniture assembly abilities, assembling the desk was a relatively straightforward process, though a little challenging due to the reasons I mentioned earlier (which I expected going in).
Desk is very sturdy. I've got a 34in monitor on an arm, a keyboard/mouse, a phone/devices charging station, and my computer on it and it all feels very secure at all of the heights I'm using. There is also still room for a portable doc cam setup or a couple of notebooks.
I love the memory function for the different heights I use, and I love being able to work at various heights, including from the floor. 15in is a little high, but with the right cushion to sit on it's working out great.
One time, the power cable accidentally caught on the foot without me realizing and the motor stopped working - I reached out to Support and received very timely support and clear instructions, and my desk is working perfectly again (and I've learned to manage my cables better!).
Very happy with this purchase, and very happy with the quality of the desk and support I've experienced.
