Head-to-head

SIHOO C300 Pro V2 vs Haworth Breck: Breck suits a shorter seat-depth need, C300 adds head support

What matters in practice

The differences that matter

Their depth ranges overlap only narrowly

The shared range is 16.9 to 17.25 inches, just 0.35 inch.

How we reached this conclusion

The overlap starts at the higher minimum, 16.9, and ends at the lower maximum, 17.25. Subtracting gives 0.35 inch.

Breck is roughly half the weight

How we reached this conclusion

59.64 minus 30 equals 29.64 lb. 59.64 divided by 30 equals 1.99.

A wider mesh seat trades against a shorter foam seat

SIHOO adds one inch of width while Breck shortens 1.9 inches farther.

How we reached this conclusion

What you give up

Every choice has a cost

If you choose SIHOO Doro C300 Pro V2

  • The official US standard version was backordered when reviewed, while the exact Amazon page showed offer-dependent availability.

If you choose Haworth Breck

  • The arms and foam seat are capable rather than plush, so very long-session comfort remains body dependent.

Recommendation switch

The decision flips if...

You want a foam seat with a wider depth range than Breck

Choose neither. Soji spans 16.25 to 18.75 inches and arrives assembled.

What matters in practice

How to make the call

01

Start with the seat-depth measurement

These chairs have surprisingly little overlap in their published seat-depth ranges. A user who fits comfortably at 16 inches should investigate Breck first. Someone who wants 18 inches cannot reach that depth on Breck, regardless of its broad-fit marketing.

02

Consider how often the chair moves

Breck weighs around 30 lb, versus 59.64 lb for C300 Pro V2. That difference matters on stairs and when rearranging a shared room. Rolling either chair on a suitable floor is different from having to lift it.

03

Decide whether the headrest earns its space

SIHOO provides an included adjustable headrest and a mesh seat. Breck keeps a lower, simpler profile. A headrest is useful only if it reaches a comfortable position during the way you recline, so check its placement before prioritizing it.

Check these before buying

  • Measure your comfortable seat height and depth before ordering. A load rating does not establish body fit.
  • Confirm the selected color, arm package and seller warranty. Optional headrests and forward tilt may require a different configuration.
  • Read the return terms before assembly. Published controls do not establish how a chair will feel after a full workday.

What this comparison cannot tell you

  • This comparison uses documented controls and dimensions. We have not measured pressure, durability or comfort in a hands-on test.
  • Manufacturer warranties depend on seller eligibility and regional terms. Neither chair is presented as treatment for pain.
