I'm certain the tumbler holder has saved me from spilling a drink on myself. It moves gracefully with the chair's various positions, always keeping the cup upright with a smooth action that instills confidence the cup will not ever come close to spilling. Even when moving to the full recline position, the cup stays upright. Today I am using a larger tumbler, and because of the size, I removed the three flexible spacers around the holder. It's a perfect fit. Even my large water bottle fits. If I decide to use a slimmer tumbler, the spacers very easily slip back on. I also like how the tumbler holder can move up and down the arm, so my drink can be very close to my hand, or farther away for people with longer arms, so you can reach to the point you feel comfortable and your cup is there. This is an essential item to go with the chair. It makes having your drink of choice a breeze, no matter what position you need to work. I highly recommend.
Excellent work station, helpful staff. Worth the money, my 4 year battle against back pain has gotten %90 better since buying this thing.
Altwork made it possible for me to get back to work! I know it will do the same for me after my back surgery b as well. Jeff was amazing!!!!
The laptop mount is very solid and holds my laptop safely and securely. My only complaint is the laptop is a bit far away from me, such that it's a stretch to use its keyboard, and this means it takes up a fair amount of space to the left of the workstation.
