Same name, higher price.
A buyer has the Doro C300 Pro open in one tab and the V2 in another. The V2 costs $104 more, yet both chairs carry DynaCore, both have a 5-year warranty, and the photos look close. Most people in that spot want to know what the extra money really buys.
This guide covers the Sihoo Doro C300 Pro V2 vs C300 Pro question using only what we state on each product page. If you are weighing Ergonomic Desk Chairs for Home and Office in Australia, this pair is a good test of when a newer model is worth paying for. Both are an ergonomic office chair with a mesh back, a 3D headrest and a seat that slides.
We also compare four independent reviews and the ratings. Then we say plainly who should save the $104.
Quick answer: Pay the $104 for the Sihoo Doro C300 Pro V2 if finer armrest control and the newer lumbar system matter to you. Keep the Sihoo Doro C300 Pro if you want the same recline, seat depth adjustment and 5-year warranty for less, and a longer public track record. Prices were checked on 2 November 2026 and move during sales.
The Sihoo Doro C300 Pro V2 vs C300 Pro Price Gap Is $104
Price is the clearest difference, so we start there. We used our sale prices as of 2 November 2026.
What each chair costs today
We list the V2 standard version at $851, with a compare-at price of $1,199. The footrest version is $871, with a compare-at price of $1,227, while we list the C300 Pro in Black and Grey at $747, with a compare-at price of $1,099. Its footrest versions cost $767, so the gap stays the same.
| Version | C300 Pro | C300 Pro V2 | Gap |
|---|---|---|---|
| Standard | $747 | $851 | $104 |
| With footrest | $767 | $871 | $104 |
What $104 means per working day
The gap is about 14% on top of the C300 Pro price. We give both chairs a 5-year warranty, so we can spread the gap over that time.
Five days a week for 48 weeks a year gives about 1,200 working days in five years. The gap then comes to roughly 9 cents per working day, which assumes the chair lasts the full warranty period, and we do not promise that.
Why the sale price needs a second look
We show crossed-out prices on both chairs, and sales change them. Check the figure on the day you buy. For a team ordering several seats, $104 multiplied by ten chairs is $1,040, so price the order both ways.
Features the Two Chairs Share
Before the differences, it helps to know how much does not change.
Recline, seat depth and warranty match on paper
Both chairs recline to 105, 120 and 135 degrees. Both have a waterfall mesh seat with a 4 cm depth adjustment, a 150 kg load limit and a 5-year warranty. Both also use DynaCore, which we say keeps the head, back, lumbar region and arms aligned as you move.
The C300 Pro has a SyncroFlex back-glide system, and the V2 uses the same SyncroFlex name, so the core frame looks alike on paper.
Why this matters when you read reviews
Reviews of the V2 often describe DynaCore, 4 cm depth adjustment and 135 degree recline as new. Some of that is new compared with the older standard Doro C300. It is not new compared with the C300 Pro, so be careful when a review praises a feature that the C300 Pro also has.
Where the Two Chairs Really Differ
Here is the side by side view, and where we publish no value, the table says so.
The full comparison table
| Feature | C300 Pro | C300 Pro V2 |
|---|---|---|
| Price (2 Nov 2026) | $747 | $851 |
| Armrests | Listed as 6D adjustable, but our comparison table says 4D | 8D Bionic armrests |
| Lumbar | Adaptive PA+ fibre lumbar, called dynamic lumbar support | Domino sacral-lumbar plus Self-Adaptive Dynamic Lumbar Support 2.0 |
| Headrest | Wide 3D, 5 cm height, 2.5 cm forward and back | Ultra-wide 3D (no ranges listed) |
| Seat depth range | 42.7 to 45.1 cm | 42.9 to 47.0 cm |
| Seat width | 51 cm | 52.1 cm |
| Recline | 105, 120, 135 degrees | 105, 120, 135 degrees |
| Weight | 25.1 kg (net 24.2 kg) | Net about 27.1 kg |
| Recommended height | 150 to 190 cm | Not listed |
| Weight limit | 150 kg | 150 kg |
| Warranty | 5 years | 5 years |
| Rating | 4.6 out of 5, 184 reviews | 4.0 out of 5, 22 reviews |
Armrests are the clearest upgrade
We list 8D Bionic armrests on the V2 but do not name the eight movements. We list 6D armrests on the C300 Pro, with height, angle, forward and back, and rotation, yet our own comparison table calls them 4D.
The "8D" label in that table belongs to the V2 column. Our C300 Pro page shows both numbers, so confirm the armrest spec with our team before you buy. Either way, the V2 claims more directions of movement.
More is not always better, because T3 and one buyer on our V2 page found the armrests move too easily. Extra directions help if you change tasks often, yet they matter less if you set the arms once and forget them.
Lumbar 2.0 and the Modes We Do Not List
We name a Self-Adaptive Dynamic Lumbar Support 2.0 on the V2 but do not list any modes. Tech Advisor and PC Guide both describe three on the V2: firm, gentle and sacrum support.
T3 and TechRadar praise the lumbar support without naming modes. So two of four reviews describe the modes, and our page does not list them.
The C300 Pro has an adaptive fibre lumbar that adjusts by itself. We cannot say how the two feel different. A short sit is the only real test, and the 30-day returns badge gives you some room.
Seat, headrest and weight
The V2 seat is a little deeper at its longest setting, 47.0 cm against 45.1 cm, and 1.1 cm wider. That may help taller people, because a deeper seat supports longer thighs, but we do not say who it is meant for.
The V2 headrest is called ultra-wide, but we give no travel figures for it, while we do for the C300 Pro.
The V2 is also heavier by our stated weights: roughly 27.1 kg net against 24.2 kg. T3's reviewer needed a colleague to lift the body onto the base, so plan for a second pair of hands.
What the Tech Advisor Review Does and Does Not Tell You
Independent reviews help most when you read them for the right chair, so here is what each one covers.
The review compared the V2 with the standard C300
Tech Advisor published a review by Simon Jary on 29 April 2026. It looked at the Sihoo Doro C300 and the C300 Pro V2.
It did not compare the V2 with the C300 Pro. Its prices were in US dollars and pounds, so they do not match Australian prices.
What it found in the V2
In the review, the V2 has three lumbar modes, a single side handle for height, recline and seat depth, and armrests that tilt upward and slide further. It also notes a wider headrest and a softer, denser mesh.
The reviewer remains a fan of the standard C300 and says the V2 is worth the extra cost if you can afford it. Its one listed con was assembly instructions that left the armrest step confusing until he scanned a QR code for a video.
What not to take from it
Those gains are measured against the standard C300, which has 110, 120 and 130 degree recline and 4D armrests according to that review. They do not carry over to the C300 Pro, and the same applies to the single-handle control and the headrest size.
We found no independent review that tests the V2 against the C300 Pro head to head. Treat the review as a guide to the V2 alone.
What Owners and Reviewers Say
This section draws on the customer reviews on our two product pages and three public reviews. Ratings are one signal and not a verdict, so we also looked at what people wrote.
The C300 Pro has the stronger track record
The C300 Pro scores 4.6 out of 5 from 184 reviews. Reviewers praise the lumbar support and the headrest most.
One reviewer says her husband, who had sciatica before, finds it very good for his back, and others mention easy assembly and fast delivery. That is a large sample, although it is only what buyers chose to post.
The V2 rating is lower and the sample is small
The V2 scores 4.0 out of 5 from 22 reviews, and we show them all. Most give 4 or 5 stars. Praise centres on the armrests, lumbar support, mesh and feature range.
The main complaints are about slow dispatch or poor communication, with buyers reporting waits of two to three weeks. Others are personal: one buyer found the lumbar too strong, a few found the armrests move too easily, and one wanted a softer seat.
With only 22 reviews, one or two unhappy buyers move the average a lot. Treat 4.0 as a prompt to check dispatch times, not a verdict on comfort.
Outside reviewers praise the V2 with caveats
T3's Bethan Morgan, writing on 20 May 2026, tested the V2 for a few weeks. She said it kept her aligned for the full 8 to 9 hours she would sit in it, and our V2 page carries a T3 Recommends badge.
She also found too many armrest options, armrests that shift with a knock, a headrest that sits too far back and fiddly assembly.
PC Guide's Charlie Noon, who is that site's affiliate manager, wrote a sponsored post that praises the lumbar modes. He also notes that the base of each arm has no left or right marking, so he fitted them wrongly at first. Because that piece is sponsored, we treat it as one view among several.
Stock and Delivery Are Part of the Decision
A great chair is only useful if it arrives, so stock shaped our advice when we first checked on 9 October 2026.
Stock has moved around
On 9 October 2026 the standard V2 showed as sold out in both Black and White, and the C300 Pro Black with footrest was sold out too.
By 2 November every version showed as available, although both chairs still carried "low on stock" and "high demand" tags. Stock moves daily, so check before you plan around a model.
Dispatch is slower than the delivery line suggests
We promise free shipping with delivery in 1 to 5 days on both chairs. We also say dispatch takes an extra 5 to 7 business days.
Add the two and you can see why some buyers waited. Our two lines do not add up neatly, so check the shipping policy at checkout, and ask support first if you need a chair by a fixed date.
Who Should Pay the $104 for the V2
Some buyers will get real value from the gap, but most will not notice it.
The V2 suits people who change tasks often
Pick the V2 if you switch between typing, calls, drawing and reading, and move your arms a lot. The extra armrest movement and the larger seat range can matter, because you use them every day.
It also suits taller users who want the 47.0 cm seat depth. The 135 degree recline is on both chairs, so do not pay extra for that.
Teams that standardise on one chair
An office with mixed heights and tasks gets more from a flexible arm, and WorkSafe Queensland says the more adjustable a chair is, the more individuals it can suit. For a fit-out of ten or more, our wholesale office chairs page covers volume orders.
Who Should Keep the C300 Pro Instead
The C300 Pro is a strong chair, and it is the cheaper one in this pair.
The C300 Pro suits most single users
If you want self-adjusting lumbar support, 4 cm seat depth adjustment, 135 degree recline and a 5-year warranty, the C300 Pro gives you all of them for $104 less. We list a 150 to 190 cm height range for it, but not for the V2. Its far larger review base makes the record easier to trust.
When another Doro makes more sense
If your budget is tighter, look at the Sihoo Doro C100. It was $459 on 2 November 2026, with a 4.7 rating from 125 reviews, a 136 kg limit and 4D armrests. Our C100 page shows two warranty figures, 3 and 5 years, so confirm with our team before you order.
If you want to go up in price, the Sihoo Doro S300 and Sihoo Doro C500 are covered in our full Doro range comparison.
When neither chair is the answer
Both chairs are heavy and sizeable. We do not list a height range for the V2 yet, so check your measurements with our guide on how to measure an office chair before buying it online. Persistent pain, numbness or leg symptoms need a GP or physiotherapist, not a new chair.
Decision Table for the Sihoo Doro C300 Pro V2 vs C300 Pro
Find the row that sounds like you.
| If you... | Choose |
|---|---|
| Switch tasks often and want finer arm control | C300 Pro V2 |
| Are tall and want the longer seat depth | C300 Pro V2 |
| Want the best-proven chair with the largest review base | C300 Pro |
| Want the same recline and 5-year warranty for less | C300 Pro |
| Set your arms once and rarely touch them | C300 Pro |
| Need the chair quickly and stock looks tight | C300 Pro, or the V2 with footrest |
| Have a tight budget | Doro C100 |
Buying With Confidence
Buy with the return window in mind
Both chairs carry a 30-day returns badge. The ACCC says a business must follow its own change-of-mind policy, and that it cannot take away your right to a repair, replacement or refund for faulty goods. It gives "no refunds" as an example of a policy that breaks these rules.
Read the terms at checkout, because they set the condition and cost of a change-of-mind return.
Conclusion
For most single buyers the C300 Pro is the sensible pick, because it matches the V2 on recline, seat depth adjustment and warranty and costs $104 less. The V2 earns its premium if you want the newer lumbar system and the finer armrests, and if you can wait for stock. Test the chair in the first few days, adjust the arms slowly, and keep the box until you are sure.
