But if youre after a more vertical sitting position, this may not be the best choice for you.
Thats largely achieved by supporting your lumbar spine using a dedicated panel that protrudes into your lower back.
The EC100 indeed has this panel, though surprisingly, it doesnt feature manual adjustment.
But I think it could be improved by allowing manual adjustment of the lumbar panel.
ProtoArc offers free shipping, a 30-day return period, and a 2-year warranty.
From unboxing to finished assembly, the process took about twenty minutes.
It also comes with all of the bolts conveniently labeled.
You should be able to put this chair together quickly, even if youre not very handy with tools.
The armrests adjust 3.5 inches vertically, but do not feature any arm pad adjustment.
The headrest adjusts 2.75 inches up and down and also rotates 60 degrees.
That pairs with a 90-130 degree adjustable seat back, which also features adaptive lumbar support.
The lumbar pad does not adjust, but flexes instead.
The seat height adjusts up and down about three total inches, which is a bit limited.
Still, ProtoArc says this desk chair is appropriate for users ranging from 53 to 65.
ProtoArc EC100 Ergonomic Mesh Office Chair: Design and comfort
The EC100 features anS-shapedback design.
That shape is intended to conform to your backs natural curves.
The seat back is made from a light and breathable mesh material that also conforms to your body nicely.
The seat bottom features layers of fabric, foam, and springs.
Its very soft and very comfortable, and its saddle-shaped to hug your body.
On that first point, the EC100 beats the odds.
On the second point, I do wish this lumbar support panel was adjustable.
As it is, the panel relies on your bodys weight and pressure against it to accommodate your position.
Thats mostly fine, unless youre not applying enough pressure on it.
If I could adjust the lumbar panel inward, I think I could have found a more comfortable position.
Consequently, I found myself wishing I could adjust the seat back more vertically.
Its pretty relaxing and comfortable.
The flexible mesh makes it even more enjoyable.
As is the case with any mesh chair like this, there are concerns about long term durability.
Will the mesh stretch and wear out?
But I would be disappointed if that mesh material stretched and lost some of its support over the years.
But thats a concern thats not exclusive to this chair.
Its soft seat bottom stands out as one of the most comfortable Ive tested.
The headrest is adjustable and very useful.
The mesh seat back is airy and comfortable.
And it ticks a lot of the comfort boxes youd get from more expensive chairs.
Its a good ergonomic budget option.
