SIHOO Office Chair: Our Unboxing And Testing Experience

Begin With the assembly, I found it to be simple and straightforward, taking me around 25 minutes to complete. The chair came with all the necessary tools and even spare parts for each component, which was a pleasant surprise. See the picture of package’s arrival at home.

Talking about the build quality of the SIHOO, the seat is made with a mesh fabric layered on top of soft white cotton, complemented by a thick foam pad for enhanced comfort. The lumbar pillow, wrapped in thick foam, provides excellent support.

In terms of dimensions, the chair offers a height range of 43.31 to 49.21 inches, a seat width of 20.87 inches, and a depth of 17.72 inches. The seat height can be adjusted from 16.93 to 20.08 inches, and it has a weight capacity of 330 pounds.

The chair features a breathable polyester mesh material for the headrest and backrest, along with a sturdy steel frame and nylon armrests with a polyurethane surface.

During the testing of mechanical adjustments, I was able to adjust the height within a range of 3.15 inches. The height adjustment knob also allows you to lock the chair in one of three different reclining positions: 110 degrees, 116 degrees, and 126 degrees. The tension knob under the seat lets you adjust the tilt’s firmness.

You can keep it unlocked for a rocking motion or lock it for stability. The lumbar support pad, located at the back, can be moved forward or backward by 1.2 inches and up and down by 1.9 inches. This feature impressed me as it provided just the right amount of support for my lower back. The armrests can be adjusted in height by 2.8 inches, ensuring optimal arm positioning.

However, it’s important to note that they don’t tilt or move forward and backward. Finally, the headrest offers a height adjustment of 3.9 inches and a rotation of 45 degrees, allowing you to find the perfect position for your neck and head.

Now, let me share what I loved about the SIHOO chair. The lumbar support pad provided excellent support and was easy to adjust to my liking, eliminating the need for additional cushions. The neck pad was also comfortable, allowing my head to rest without any strain. The mesh fabric used throughout the chair felt supportive and durable, giving me confidence in its longevity. With its 330-pound weight capacity, the chair felt solid and reliable.

Whether I was editing for long hours or indulging in gaming sessions, the chair offered exceptional comfort. Lastly, the current price of £150 for the black version makes it a fantastic deal. It rivals chairs that typically cost much more, ranging from £300 to £500.

To be honest, I couldn’t find any negatives to mention about the SIHOO M18 chair. However, before making a purchase, it’s important to consider a few things. While the chair offers most of the essential adjustments, it lacks some of the advanced features found in higher-priced chairs. For example, the armrests don’t tilt or move forward and backward.

Personally, I didn’t find this to be a crucial feature as I prefer setting the armrests in my preferred position and leaving them there. Additionally, the seat cushion doesn’t tilt or slide back and forth; it remains fixed. Nevertheless, the larger pad size of the SIHOO M18 compensates for the lack of adjustability, providing ample surface area and comfort for extended sitting sessions.

Kerdom Office Chair: Our Unboxing And Testing Experience

This arrived a week later. Just like SIHOO, took only 20 minutes. The quality of the construction impressed me, as the chair is primarily made of sturdy plastic. The only non-plastic parts are the piston under the seat and the lever for adjusting the chair’s height.

It was convenient that all the necessary tools for assembly were included in the box. I also appreciated the inclusion of spare parts for future replacements.

The first comfort I must say, it didn’t disappoint. The headrest was perfectly positioned for my height, and I liked the option to adjust it up and down for a custom fit. The chair’s swivel feature allowed me to move around effortlessly.

The backrest provided excellent lumbar support exactly where I needed it. It was great to have the flexibility to adjust the backrest vertically as well. The chair’s substantial recline added another level of comfort, perfect for moments when I wanted to relax. Although reclining fully required some pressure on my toes, it was well worth it for the added relaxation it provided.

I appreciated the ability to adjust the armrests, allowing them to be raised and moved out of the way. This feature came in handy when I needed to position the chair closer to my desk. Conversely, when I wanted to use the armrests, I could easily lower them, providing a comfortable resting place for my elbows.

Another notable feature was the lever that controlled the chair’s tilt resistance. It allowed me to customize the ease or difficulty of leaning back, depending on my preference. Additionally, the lever served to adjust the chair’s height, making it versatile for various desk heights and user preferences.

The chair’s backrest and headrest are covered in a forgiving mesh material that adapts to the shape of my head and back. This ensured excellent support and comfort when leaning back in the chair.

Despite its primarily plastic construction, the chair felt solid and sturdy. Its lightweight design, facilitated by the plastic build, made it effortless to move around, even on carpeted surfaces. This lightweight and portable nature proved especially useful for those who unexpectedly found themselves working from home, allowing for easy relocation and adaptability to different environments.

Like many others, I had experienced discomfort and back pain and this Kerdom Office Chair addressed these issues effectively. The chair’s lumbar support filled the gap between my back and the chair, promoting proper spinal alignment.

The ability to fold up the armrests not only helped with closer positioning to my work area but also encouraged better posture. The chair’s design eliminated any gaps between my back and the chair, providing much-needed support. It has successfully addressed the deficiencies of my previous cheap Comhoma chair, lacking essentials such as armrests, a headrest, and lumbar support.

SIHOO Vs Kerdom: Comparison

SIHOO Vs Kerdom: Design And Support

Both the SIHOO and Kerdom office chairs have ergonomic designs, aiming to provide optimal support and comfort during long hours of sitting. They feature a contoured backrest, adjustable lumbar support, and a headrest to maintain proper spinal alignment and reduce fatigue. However, in terms of design aesthetics, the SIHOO chair offers a modern and sleek appearance with clean lines, while the Kerdom office chair has a more classic and traditional design.

While both chairs have adjustable lumbar support, the design and effectiveness of their lumbar support systems differ. The SIHOO chair has a lumbar pillow that can be moved up and down and adjusted for firmness, while the Kerdom chair’s lumbar support is integrated into the backrest, offering a more fixed position.

SIHOO Vs Kerdom: Adjustment Difference

Both chairs offer adjustable seat height, allowing users to find the most comfortable position for their desk height and body proportions. This is a crucial feature, especially for people of different heights and those with height-adjustable desks.

While both chairs offer a tilt mechanism, the range of recline angles differs. The SIHOO chair provides three recline positions (110 degrees, 116 degrees, and 126 degrees), whereas the Kerdom chair offers a wider range of angles, including a full recline position for relaxation.

Although both chairs have adjustable armrests, the level of adjustability varies. The SIHOO chair allows users to adjust the armrest height, but they are fixed in position otherwise. On the contrary, the Kerdom chair’s armrests can be adjusted in height, angle, and even width, offering a higher degree of customization.

The headrest design varies between the two chairs. The SIHOO chair has a height-adjustable headrest that can also be rotated, providing flexibility in finding the perfect position for neck and head support. On the other hand, the Kerdom chair has a fixed headrest that may not be as customizable for some users.

SIHOO Vs Kerdom: Weight Capacity And Price

Both chairs boast a sturdy construction and have a weight capacity that can accommodate most users, with the SIHOO chair supporting up to 330 pounds and the Kerdom chair supporting up to 300 pounds.

The SIHOO and Kerdom chairs differ in terms of their price range. The SIHOO chair generally falls within a more affordable price range, making it an attractive option for budget-conscious buyers. On the other hand, the Kerdom chair tends to be priced slightly higher, reflecting its premium features and build quality.


In conclusion, both the SIHOO and Kerdom office chairs offer a range of features aimed at providing ergonomic support and comfort for long hours of sitting. They share similarities such as ergonomic design, adjustable height, tilt mechanisms, breathable materials, and sturdy construction. However, they also have noticeable differences in design aesthetics, lumbar support, headrest design, recline angles, armrest adjustability, and price range.

Ultimately, the choice between the SIHOO and Kerdom office chairs will depend on individual preferences, specific needs, and budget considerations. If you value a sleek modern design and affordability, the SIHOO chair might be the right choice for you. On the other hand, if you prioritize customizable lumbar support, and a wider range of recline angles, and are willing to invest in a premium chair, the Kerdom chair could be the ideal option.
