## Features

- 【Dual Dynamic Lumbar Support】Sihoo's latest ergonomic chair, Doro S100, sets itself apart from traditional office chairs with its dual dynamic lumbar support. Featuring the newest dynamic adaptive mechanism and four springs, it offers 6D automatic adjustment, dynamically adapting to various body shapes and postures, providing comprehensive and enveloping lumbar support. This ultimately ensures a higher level of seating comfort.
- 【4D Coordinated Armrest】High-end ergonomic office chairs deserve equally sophisticated armrests. Doro S100 features a pair of 4D armrests with an ultra-soft and thick surface. These armrests can be adjusted up and down by 2.76 inches (7 cm), back and forth by 1.18 inches (3 cm), and inward and outward by 72°, coordinating with the backrest when reclining. You get to enjoy arm support in four directions, helping alleviate the strain on your shoulders whenever you're working, studying, and more.
- 【Advanced Independent Backrest】Doro S100 series utilizes high-resilience mesh fabric, offering an elevated back support experience. The chair back is independently adjustable, allowing the upper half to be positioned in 5 levels. Whether you are 5' (150 cm) or 6'3" (190 cm) tall, you can enjoy comprehensive support for your shoulders and neck. Additionally, the dual-wing lumbar support provides precise support to your lower back, effectively supporting your waist.
- 【Adjustable Pressure-Free Seat Cushion】Sihoo Doro S100 series offers a seat depth adjustment range of 1.97 inches (5 cm). In addition, the seat cushion utilizes a waterfall-shaped design, effectively maximizing the contact area with the thighs and hips. This remains true even when you are in motion, ultimately minimizing pressure to the greatest extent possible and ensuring unobstructed blood flow.
- 【Premium Quality Ergonomic Chair】Sihoo prioritizes both product quality and customer service. Doro S100 not only features a premium aesthetic and ergonomic design, but also utilizes higher-quality materials and boasts a more efficient after-sales service team. BIFMA and SGS certifications guarantee many years of enjoying the chair's ergonomic comfort.

## Customer Reviews

### ⭐⭐⭐⭐ Great for the price
*by J***E on November 4, 2024*

I bought this from the Sihoo website. I really like the lumbar support versus the traditional pillow like setup most chairs have. One thing that was odd at this price point is that there was no seat tilt option (just a slide option). My only complaint is that I have a long-ish spine and the arm rests do not quite come up enough to support my elbows, which puts strain on my shoulders. Some minor tweaks to the chair fix it, but I think more functionality (7-8 settings vs 6) on the armrest would really sell it.

### ⭐⭐⭐ First-day Review (S100): Hard to assemble, loud, heavy, a little clunky
*by D***O on October 6, 2024*

The packaging contains customary extra screws and spacers, but arbitrarily more than the +1 advertised, which may be good or bad for some.I don't know if it's a design problem or bad luck in a build I received, but the chair legs and wheels were extremely difficult to insert. The tutorial video shows them all sliding in gently and easily, right away, but I had to struggle for an hour with brute force. The legs would not slide on quite far enough, maybe a millimeter short, to get the screws in evenly - but probably within tolerance for the sake of mere sitting. The wheels, I'm not sure how I finally managed to insert, but there was never a trick I found.Some of the adjustable settings make a lot of mechanical noise when acted on, especially the seatback, and armrest orientation and height adjustments, and sometimes the chair height adjustment. I'm used to no noise at all, albeit with chairs featuring just a height adjustment.The seat (horizontal) adjuster makes some noise by delay and it is hard to control.The armrest can only be lowered from the highest of 7 settings, and the highest setting does not appear to be maintainable either, as any pressure will immediately lower it back to the lowest setting; that seems somewhat inconvenient, though the default works for me.I would echo complaints about the limitations of the armrest rotation. While it can only rotate up to may 105° out from the chair (default is perpendicular), it can rotate as close as 30° inwards, which nestles right into the abdomen of even a skinny sitter. Such a close rotation seems useless to me; I could have used a 150° setting instead. The armrests are also indeed too flexible.The reclination is good for what it is, but more control would have been better.The chair spins a bit too easily for my taste.Finally, the chair is shockingly heavy. My previous chair was not lightweight - maybe up to 20 lb - but the S100 must be at least twice that. Don't expect to carry it about often.The sitting seems fine, to the extent I have the capacity to judge such things. The convex seat may turn out to be less comfortable to sit on for prolonged periods compared to a traditional one, but I'm not sure.

### ⭐⭐⭐⭐⭐ Works as advertised
*by T***J on October 24, 2024*

The chair is excellent and functions as advertised. It took me some time to adjust to the lumbar support, but it ultimately helped me maintain proper posture and work for long hours at my desk.
