Sihoo V1 vs M90: Simple Truths from Real Work Hours

Last Updated on November 2, 2025 by Cassie Moorhead

When comparing sihoo v1 vs m90, the real difference comes down to comfort and how long you sit each day. Both chairs work well, but they feel very different in daily use. I’ve used them for long work hours, and each one has strengths that show up over time. I’ll break it down in simple terms so you can pick the one that fits your work style.

SIHOO V1 Review

The SIHOO V1 High Back Office Chair is a solid ergonomic office chair that works well for daily work and long hours. I found it supportive and easy to adjust, especially when sitting for many hours at my desk. The mesh back keeps the seat cool, and the 4D lumbar support helps my lower back stay aligned. If you work from home or in an office and need real comfort, this chair offers dependable support without feeling stiff. In short, it feels like a chair built for real work, not just looks.

What I Like

• Strong ergonomic support
  The 4D lumbar support really helps my posture. I notice less lower-back strain during long typing sessions.
• Breathable mesh back
  The mesh design keeps me cool. I do not get sweaty like I do in padded chairs.
• Easy adjustability
  The adjustable headrest, armrests, and backrest tilt make it easy to set the chair to my body. It fits me rather than making me fit it.
• Feels stable and well-built
  The aluminum alloy base feels strong and steady. The chair does not wobble or feel cheap.

What Could Be Better

• Assembly takes time
  It was not hard, but it did take patience to attach some parts.
• Seat cushion could be thicker
  It is fine for most days. But if you sit 10+ hours, you may want a small seat cushion topper.
• Not ideal for very short or very tall users
  The adjustment range is good, but some people may find the fit less precise.

The SIHOO V1 is a good fit for people who spend long hours working at a desk, especially remote workers, freelancers, students, and anyone building a work-from-home setup. If you care about good back support, breathable materials, and many adjustment options, this chair gives real value.

However, if you prefer a very soft cushion seat or need support for extra-tall or extra-short height ranges, you may want to check sizing details before buying.

SIHOO M90 Review

The SIHOO M90 ergonomic office chair is built for daily comfort and long sitting hours. I found the lumbar support gentle but steady, which helped reduce pressure in my lower back. The 3D armrests also made it easy to relax my arms in different positions while typing, taking calls, or leaning back. If you work from home or spend many hours at a desk, the M90 offers a calm and supportive sitting experience. In short, it feels made for real, everyday work comfort.

What I Like

• Comfort-focused lumbar support
  The lumbar support feels natural. It doesn’t push too hard. It helps my spine stay upright in a relaxed way.
• Soft and supportive seat cushion
  The high-density foam cushion has a W-shaped seat. It spreads weight well. My legs feel less tired at the end of the day.
• Easy adjustment for many body types
  The adjustable backrest height and 3D armrests make the chair fit better to me, not the other way around.
• Breathable mesh keeps me cool
  The breathable mesh fabric is a big plus. I feel less heat, especially during longer work sessions.

What Could Be Better

• Recline tension takes time to fine-tune
  It works, but I had to adjust a few times to get it just right.
• Seat cushion may soften with very heavy use
  It is comfortable now. But I can see it wearing faster if used 10+ hours a day, every day.
• Assembly instructions could be clearer
  I got it done, but a few steps felt confusing at first glance.

Recommendation

The SIHOO M90 is a good match for people who want comfort first, especially those who spend long hours sitting and want less pressure on their lower back and legs. If you type a lot, attend online meetings, or work from home, the lumbar support and 3D armrests help reduce strain during the day.

However, if you prefer a firm or very posture-correcting chair, you may want to try it in person or check return policies first. The cushion is comfortable, but softer than some chairs built for very strong posture hold.

For most USA remote workers, the SIHOO M90 fits well into a home office setup because it supports comfort, airflow, and steady posture without feeling stiff or bulky.
