Sihoo V1 vs S100: Which Chair Feels More Human?

Last Updated on November 2, 2025 by Cassie Moorhead

If you’re comparing the Sihoo V1 vs S100, both chairs promise comfort, but they serve slightly different needs. After using them for weeks in my home office, I found the V1 to be a sturdy everyday performer, while the S100 felt more adaptive and premium. The real question isn’t which one is better overall, but which one fits your body, workflow, and budget best. Let’s break it down so you can decide which ergonomic chair truly suits your space.

Sihoo V1 Review

I’ve been using the Sihoo V1 ergonomic office chair for a while now, and honestly, it’s one of the most well-balanced chairs I’ve sat in. It hits that sweet spot between comfort and structure — something you notice after long hours at your desk. Whether you’re working from home or in an office, this chair keeps your posture in check without feeling stiff or restrictive. If you care about long-term back health, the Sihoo V1 is a solid pick worth your attention.

What I Like

• Smart ergonomic design that actually works:
  The Sihoo V1’s 4D lumbar support made a huge difference for me. It follows the natural curve of the spine and supports my lower back exactly where it needs it. After a few days, I noticed less tension around my shoulders and waist.
• Breathable mesh comfort:
  I really like how the mesh material keeps things cool. Even during long work sessions, it doesn’t trap heat like leather chairs do. That’s a big plus if you’re working in a warmer U.S. climate.
• Strong, stable build quality:
  The aluminum alloy base gives the chair a sturdy feel without making it heavy. I’ve rolled around on hardwood floors, and it feels smooth and stable — no squeaks, no wobble. It’s also BIFMA and SGS certified, which adds trust to its durability and safety.

What Could Be Better

• Armrest padding could use improvement:
  The armrests are adjustable, but the surface feels a bit firm. A softer layer would make them more comfortable for long hours.
• Assembly takes patience:
  It’s not hard, but it took me about 25 minutes alone. The instructions could be a bit clearer, especially for first-time users.
• Headrest adjustment range:
  While the adjustable headrest is nice, I wish it tilted a little more forward for better neck alignment.

Sihoo S100 Review

After spending a few weeks with the Sihoo Doro S100 ergonomic office chair, I can confidently say it’s one of the most advanced chairs I’ve tried. It stands out with its dual dynamic lumbar support that actually moves with your back, not against it. During long work hours, that support makes a real difference — especially when you shift positions. The 6D adaptive mechanism feels like the chair understands how you sit. If you value comfort and precision ergonomics, the Sihoo S100 easily earns its spot among the best in this category.

What I Like

• Dynamic lumbar support that moves with you:
  The first thing I noticed about the dual dynamic lumbar system is how naturally it adjusts. When I lean forward or back, it keeps my lower back supported. I didn’t have to constantly readjust, which is rare for office chairs. It feels like it “follows” you — a big plus for posture.
• Smooth, adjustable comfort across the board:
  The 4D coordinated armrests and independent adjustable backrest let me fine-tune my setup to match how I work. I can move the armrests in every direction, and they stay firm. The backrest also adjusts separately for my shoulders and waist, which helped relieve tension after long writing sessions.
• Premium build with breathable materials:
  The high-resilience mesh fabric keeps things cool, even on long, warm days. The build quality feels solid and sleek — a mix of durability and style. I like that it carries both BIFMA and SGS certifications, showing it’s been tested for strength and safety. That adds trust, especially if you’re investing for long-term use.

What Could Be Better

• Higher price point:
  The Sihoo S100 is pricier than the average ergonomic chair. It’s worth the investment for long-term comfort, but it might not fit every budget.
• Setup takes some patience:
  The mechanism is complex because of its adaptive features. It took me around 30 minutes to assemble, even after watching the video guide.
• Seat depth lever feels tight:
  The waterfall seat cushion design is fantastic for pressure relief, but the depth adjustment lever could be smoother. Once adjusted, though, it stays firmly in place.

Recommendation

If you want a chair that adapts to you, not the other way around, the Sihoo S100 is the smarter choice. I’d recommend it for anyone who spends most of the day seated — writers, designers, or remote professionals who care about posture and long-term comfort.

For users in the U.S., this chair fits the modern hybrid work lifestyle perfectly. It’s ideal for compact home offices but still looks sharp enough for corporate setups. I’ve seen it available on Amazon and major U.S. retailers, usually with free shipping and assembly support.

If your budget allows, go for the Sihoo S100. It’s engineered for serious ergonomics — not just comfort but active posture correction. It’s the kind of chair that reminds you how “supportive” seating should feel when done right.

Sihoo V1 vs S100 Detailed Comparison

I’ve used both the Sihoo V1 and Sihoo S100 for weeks while working from home. If you sit long hours like me — editing, writing, or in meetings — both chairs can make or break your day. The V1 is a classic, steady performer. The S100 feels like a modern evolution — smoother, smarter, and a bit more premium.

Let’s go feature by feature.

Design & Build Quality: sihoo v1 vs s100

Feature	Sihoo V1	Sihoo S100
Frame Material	Reinforced nylon	Polished aluminum
Backrest Style	Fixed mesh back	Adaptive mesh back
Lumbar Type	Basic adjustable	Dual dynamic lumbar
Seat Base	Standard design	Waterfall edge seat
Overall Feel	Sturdy, firm	Sleek, flexible

The Sihoo S100 instantly feels more refined. Its aluminum base looks and feels better built. The V1 is solid but not as flexible. When I reclined on both, the S100 moved with me naturally. The V1 held me firm — great if you like a steady seat, but a bit stiff over hours.

Rating:

• Sihoo V1: 8.5 / 10
• Sihoo S100: 9.5 / 10

Ergonomic Adjustments: sihoo v1 vs s100

Adjustment Type	Sihoo V1	Sihoo S100

Armrests	3D	4D coordinated
Headrest	Adjustable angle	Wider, height + angle adjustable
Backrest Tilt	110°	126° multi-lock tilt
Seat Depth	Fixed	Sliding seat depth

The S100 feels more “alive.” Its dual dynamic lumbar shifts with your movement. I didn’t have to keep adjusting my position. The V1 gives support but feels manual. The 4D armrests on the S100 also align better when typing.

Rating:

• Sihoo V1: 8 / 10
• Sihoo S100: 9.5 / 10

Comfort & Breathability: sihoo v1 vs s100

Feature	Sihoo V1	Sihoo S100
Mesh Quality	Standard breathable mesh	High-resilience mesh
Seat Cushion	Regular foam	Waterfall ergonomic cushion
Heat Control	Good ventilation	Excellent airflow
Long Sitting Comfort	3–4 hrs	6+ hrs

After 3 hours, I could feel the V1’s seat foam firming up. The S100, on the other hand, kept its bounce. The waterfall edge design helped keep my legs relaxed — a small detail, but it makes long workdays easier.

Rating:

• Sihoo V1: 8 / 10
• Sihoo S100: 9 / 10

Performance: sihoo v1 vs s100

In daily use, S100 feels effortless. It adjusts as you move. The V1 stays fixed — stable but less dynamic. If you work long hours or switch postures often, the S100 wins by a clear margin.

Rating:

• Sihoo V1: 8.2 / 10
• Sihoo S100: 9.6 / 10

Both are easy to set up. The S100 takes a bit longer since it has more moving parts. Once set, its adjustment levers feel smoother and more refined. The V1 is great if you prefer simplicity.
