Key difference: The C300 Pro V2 lists about $1,300 lower, but the Aeron carries a 12-year warranty.
The Aeron figures come from Herman Miller's spec documents and store, the C300 Pro V2 figures from SIHOO's store; prices are regular US list prices, and Chairpedia has not tested either chair.
Why compare them
Why put the SIHOO Doro C300 Pro V2 next to the Herman Miller Aeron? The Aeron is Herman Miller's long-running reference chair; the Doro C300 Pro V2 lists at a fraction of its price, so the useful question is which features the extra money actually adds.
Chairpedia has not tested the durability or comfort of the SIHOO Doro C300 Pro V2 or the Herman Miller Aeron; matching figures on paper do not mean the two chairs are built or feel the same.
