Vari Electric Standing Desk 60" Top

I've been working from home for about 3 years now. My Dr recommended that I start standing and or walking every 30 minutes because being seated for prolonged periods is causing lower back issues in conjunction with previous injuries. Looking at many options in this price range this desk caught my attention. Photos and reviews along with specifications sounded promising. I purchased the 48" with the cross bar in black. Packaging did its job however unwilling say I was very concerned when the first piece arrived. The box looked like it was used as a wheel on the truck to deliver it. All corners were crushed in and I could stick my arm into the box on two ends. It would have been nice to know that it was being shipped in two seperate boxes with different arrival times. I nearly asked for a refund assuming I purchased the wrong item... Onto the great! Being heavy doesnt always constitute quality however in this case I believe the materials used seem to be very strong and sturdy. The metal frame seems to have been made with a thick gauge steel with good looking welds. I got the black wood top and without cutting into it, it looks like a heavy MDF however I do see that they use real wood for thier other finishes which might be the case with this one. But the paint seems to look textured like MDF when its painted. Not an issue if the MDF doesn't swell up in the future. Assembly was very intuitive and all the needed tools were included with the desk which I found to be very nice. Even a rubber mallet was included. The controls feel good to the touch and the functionality of lowering and raising is smooth. I still haven't been able to program the different height settings using the included instructions so I'll need to see if I can find a video of this process to make sure I'm doing it correctly. Essentially it seems that the Lock lowest setting and setting the position 1 use the same process. Holding 1 and S at the same time and when I want to save the second height holding 2 and S at the same time it unlocks the lowest setting. So I'm a bit confused with that lock feature and setting the desired heights. Overall I'm very impressed with the quality and functionality, its not too noisy or clunky. Sounds like it might be on a screw shaft for height adjustment which is nice. Hope this initial review helps.
