Sihoo Ergonomic Office Chair design  

The all-black Sihoo Ergonomic Office Chair has a minimalist, austere, clinical appearance — it’s the type of chair you’d find in a corporate boardroom or a medical office. No, it’s not wrapped and padded with luxe materials like premium leather or Italian-imported chenille. Instead, it has a bare bones design with a breathable, mesh backrest, making it easier to clean in environments where sterilization and disinfection are of utmost importance — a plus in a world that’s evolving to be more health-conscious.

Looking at the back of the mesh chair, two striking parts may catch your eye: the ergonomic, taco-shaped headrest and ultra-curvy, extended lumbar support. I’ll discuss the comfortability of this duo in the following section. The onyx seat cushion is nothing to write home about. It has a ho-hum, tightly woven design, and is made of polyethylene and polyester.

Black double armrests wrapped in polyurethane (PU) leather flank the cushion; they’re too short for my taste. They’re about 10 inches in length — the armrests on my time-worn office chair are at least 20 inches long.

Breaking away from the all-black monotony is the aluminum alloy chair legs with smooth-running, PU-wrapped castors. Overall, the build quality of this chair is excellent — durability is seemingly one of its strengths. Sihoo says the “long-lasting chair” keeps wear and tear at bay, and I believe it.

The Ergonomic Office Chair’s dimensions are 29.9 (L) x 15.4 (W) and 25.6 (H). It weighs 40 pounds. According to Sihoo, it can handle up to 330 pounds of human.

Sihoo Ergonomic Office Chair comfort   

As mentioned at the outset, the Sihoo Ergonomic Office Chair isn’t going to coddle you, so don’t expect a cozy, cushy reception. When I first sat on the chair after assembling it, it was as if it wagged its finger furiously and said, “Aht, aht, aht! Straighten that posture, missy!” My spine automatically uncurled itself from my poor habit of hunching, thanks to the lumbar support that promotes straighter alignment and complements the inward curvature of my lower back.

The mesh backrest is ideal for workers in warmer climates — nothing is ickier than sitting on a hot pleather office chair and feeling your skin unstick from the backrest like a stubborn bandaid. It’s, indeed breathable, allowing your back to remain cool and well ventilated, even as the temperature starts to climb.

I also dig the chair’s adjustability. One can easily customize the height and angle of the armrests — you can also bring them closer to your body or push them further away. The recline-friendly backrest can tilt to a maximum of 123 degrees, allowing you to kick your feet up to relax or read a book. Easily accessible via a lever, the backrest also has a three-gear height adjustment feature. Satisfying my attention deficit, the Sihoo Ergonomic Office Chair lets me swivel around a full 360 degrees over and over again while I conjure up new ideas for Laptop Mag. The headrest is another adjustable feature, allowing users to increase its height by two inches.

Regrettably, one thing I don’t like about the Sihoo Ergonomic Office Chair is that it feels somewhat stiff. The seat cushion is unforgiving. Sihoo claims that it’s “spongy,” but it feels more like an ultra-firm mattress. To be fair, I’ve spent less than a week with the Sihoo-branded chair, so perhaps the sitting experience will become softer and more cushiony as I “break” into it.

Sihoo Ergonomic Office Chair assembly

Scrolling through the Amazon comments for the Sihoo Ergonomic Office Chair, a common complaint is that the instruction manual isn’t clear.

As such, I was bracing myself for a confusing, incomprehensible installation guide, but surprisingly, it was more intelligible than I anticipated. On the plus side, there’s a well-labeled parts list with an illustration for each item, including the “lever mechanism” (for modifying the chair’s height), the handy hex wrench, and a variety of screws and washers. As such, while you’re reading the step-by-step instructions, you know exactly which item the manual is referring to just by matching the illustration with the physical part.

I also appreciated that screws and washers, both coming in different sizes, were packaged, grouped and labeled for users’ convenience. For example, a group of screws for the armrests were labeled “M6-30.” In the manual, I was told to “use four M6-30 screws” to set up the armrests, so it was easy for me to quickly grab the tools that I needed to assemble the chair — without fretting over whether I had the right parts. By the way, there are some spare screws and washers — just in case you accidentally lose a few while putting the chair together.

I do have some gripes, though. The illustration that accompanies each step in the manual could be less ambiguous — the visuals should be larger and the depiction of where the screws and washers must be clearer. Also, some of the commands aren’t accurate. For example, in the first step, it tells you to “screw the castors” into the metal base. My dad and I tried screwing the castors in, twisting with all our might, but it refused to go in. It wasn’t until my dad jammed the wheels into the legs — and they finally locked into place — that we realized “ram the castors into the holes” would be a more fitting command.
