Question: What is the weight of the chair? Is it easy to lift and move?
Document: I am satisfied with the product. It is light weight and easy to move around, stable and easy to adjust. It is not comfortable to sit upon for extended amounts of time. I have a sit to stand work station so it fits my needs well.
Great office chair. Seat bends forward to allow you to take weight off your spine. The core flexibility allows for stretching to reach things without toppling over, since the base does not move at all.Just me personally, I get a bit uncomfortable by the end of a long day because there is not a lot of padding in the seat for someone like me who has 'no junk in the trunk', if you know what I mean.
Using this chair I can feel those muscles loosening up already, and do not experience the ache in my knees anymore.So far I'm loving the chair- it's not so wobbly that you move when you don't want to, but it allows for very easy, natural movement when you do. I like that the height is so easily adjusted. Like others, I had looked at a similar chair that costs 3 times as much- I'm happy I chose this one instead.
No more back pain!I love being able to move around on my chair! I know this is going to be really good for my kore and back muscles!
I really don't have to move the chair once it's in position since I only need to straddle it in order to sit down or get up -- no need to slide it back and forth like a typical desk chair.
I wasnt sure at first. This chair looks simple but has a lot to offer. I was turning into a fat cat with my regular office chair. With this i feel motivated to move around. It is comfortable and seems well made. Goodbye gut!
Comfortable, adjustable, lets back flexSitting in a regular office chair over the years caused my lower back to be stiff. This stool allows me to move around while spending a significant part of the day in front of a computer. It invites my back to wiggle.
So far I realy like the chair,  love the adjustable height, no slide base and easy assembly, thank you.
Chair is comfortable, looks nice and really does work those core muscles.only complaint is that the handle attached to the lever that raises and lowers the seat falls off easy..not the lever itself, just the handle.
The chair arrived and was very easy to set up. The paint work was not so great, peeling paint on the underside with rust showing through. Considering the cost of the chair, I think the quality could be better.
Answer: Very easy to lift.I would say not more than 5lbs.I replaced my old office chair with wheels with this, and i do have to move it to switch between my work stations. Very easy to do with one hand.
