I purchased 2 of these desks (180x80) for myself and my husband and it has been the most painless experience I think I've have the pleasure of going through when purchasing an item online. They are very well packed to ensure they arrive without any damage.
The desks arrived on the 2nd working day (ordered Thursday at 11pm and arrived on Monday 10am) so delivery was extremely fast and painless. Assembly was pretty straight forward, as a short woman I was able to assemble both desks on my own in about 4 hours (including dismantling an old desk) so I would say assembly was pain free and instructions were extremely clear (I would advise using an electric screwdriver as I only had a manual one and had to put a lot of elbow grease in for some of the screws but it is do-able).
The mechanism is so quiet and works immediately, there is no 2-5 seconds buffer whilst the motor kicks in, it is seamless and fluid movement. As we have the 180cm desk, we did have concerns that it wouldn't be sturdy as it's so big but this desk is so sturdy, even when raised, there is no moving or wobbling when typing, it's just perfectly still.
The communication I received from Elaine at Ergo was also impeccable! I got an email the next day after my purchase to pick a delivery date and on the day we communicated and responses were instant. Many companies could learn a lot from Ergo about customer service as the service I received was top level.
The quality of the desks seem so good, they're very sturdy and solid compared to my old desk (which was chipboard) and it looks really stylish.
I really have no complaints and if you're thinking of getting a standing/sitting desk, Ergodesks is really the place to go! I will definitely recommend and buy again if I am in the market again.
