Main trade-off
SIHOO Doro C300 Pro V2
The large number of moving parts takes time to tune, and the 8D arms may feel overactive.
Head-to-head
SIHOO Doro C300 Pro V2 vs C300: Pro V2 adjusts seat depth for a closer body fit
The short answer
C300 Pro V2 is the stronger choice for adjustable depth, taller users and arm support. Standard C300 retains the flexible, breathable feel with a simpler adjustment set.

About this comparison
Measure the newer Pro V2 controls against the simpler C300.
The practical choice turns on seat depth and arms, then on the constraints in your own setup.
Before you choose
How they fit your plans
A seat slide can make a shared C300 setup more practical
When two people need different thigh support, the Pro V2 lets them reset seat depth between 16.9 and 18.5 inches. The original C300 should be tried at its fixed depth before being chosen for the same job. Choose Pro V2 only if that range covers the users’ needs. More adjustable arms and a headrest cannot compensate for a seat that is still too deep at its shortest setting.
Facts behind this advice
Pro V2 supplies a 1.6-inch seat-depth adjustment range. The original C300 does not provide the same adjustable-depth control in the reviewed model.
Check the reclined position you actually use
A buyer who reads while reclined should test head support and arm reach at the chosen stop, not just with the chair upright. Pro V2 documents 105, 120 and 135-degree positions with a 3D headrest and synchronized arms. Choose it if that combination supports your reading posture. Keep the original C300 in consideration when its headrest and coordinated-arm movement already suit the same position.
Facts behind this advice
Both reviewed models include a headrest and moving arm system. Pro V2 specifies three recline positions. A deeper listed angle alone does not prove better neck support.
