The Sihoo M18 Office Chair is a product of Sihoo, a company that has made a name for itself in the office furniture industry.

The chair is designed to provide ergonomic support for individuals who spend long hours at a desk, whether for work or leisure.

The chair’s design and features aim to alleviate the discomfort and health issues that can arise from prolonged sitting.

Design and Features


The Sihoo M18 Office Chair is a blend of aesthetics and functionality. It features a breathable mesh fabric that keeps you cool and comfortable, even after long hours of use.

The chair’s W-shaped premium cushion is designed to bear weight effectively, providing comfort for extended periods of sitting.

The chair’s design includes a triple relaxation back support that provides care for the cervical vertebrae, shoulder support, and lumbar intimate care.

The chair also features a multi-dimensional adjustable headrest that can rotate 45 degrees and adjust up and down by 3.5 inches.

The armrests, while only adjustable up and down, are designed with a soft plastic and a concaved dip in the middle for added comfort.

The chair’s overall height can be adjusted within a 3.15-inch total range, making it suitable for people between 5’6″ to 6’2″ tall.

Unboxing and Setup


The Sihoo M18 Office Chair arrives in a well-packaged box, with each component neatly wrapped and secured to prevent any damage during transit.

Upon opening the box, you are greeted with an easy-to-follow instruction manual that guides you through the assembly process.

The manual is detailed and includes clear diagrams, making the assembly process straightforward and hassle-free.

The assembly process takes approximately 30 to 45 minutes, depending on your familiarity with assembling furniture. It does not require any special tools, as everything you need is included in the box.

The chair’s base is built first, followed by the attachment of the armrests. The mechanism piece is then attached to the underside of the chair’s mesh seat.

Each step is clearly outlined in the manual, and the parts are labeled to ensure you know exactly where each piece goes.

Build Quality


The Sihoo M18 Office Chair boasts a high-quality build that is designed to last. The chair’s legs and hydraulic lift piece are made of sturdy aluminum alloy, ensuring stability and durability.

The mechanism piece, which allows for the chair’s adjustability features, is made of a different metal that is equally robust.

The armrests are covered with a more flexible plastic, providing a comfortable resting place for your arms while you work.

The backrest is covered with a breathable hollow mesh that promotes airflow, keeping you cool during long hours of use.

The seat and headrest are decked out with a comfortable, cushy material that provides excellent support.

This material is then covered with a breathable mesh outer layer, adding to the chair’s overall comfort and aesthetic appeal.

Adjustability and Ergonomics


The Sihoo M18 Office Chair is designed with adjustability and ergonomics in mind. The chair’s overall height, headrest, and lumbar support can all be adjusted to fit the user’s needs, ensuring a comfortable and supportive seating experience.

The chair also features a push/pull mechanism that allows the user to switch between an upright position and a tilting position. This feature is particularly useful for those who like to lean back and relax during breaks or when thinking through complex problems.

The headrest can be adjusted to provide optimal support for the user’s head and neck. This feature is especially beneficial for those who spend long hours at a desk, as it can help to prevent neck strain and discomfort.

The armrests, while only adjustable up and down, are designed to provide comfort and support. They are covered with a soft plastic material that is gentle on the arms, and their height can be adjusted to align with your desk and keyboard, promoting good posture.

The chair also features a backrest tilt and recline feature, allowing the user to switch between an upright position and a relaxing tilted position with ease.

Height can be adjusted within a 3.15-inch total range, making it suitable for people between 5’6″ to 6’2″ tall. This feature ensures that you can position the chair at the perfect height for your desk, promoting good posture and reducing the risk of back pain and other discomforts.

The chair also features a lumbar support adjustment that can move up and down and forward and backward. This feature provides optimal support for the user’s lumbar spine, helping to prevent lower back pain and discomfort.

Comfort

The mesh fabric promotes airflow, keeping you cool and comfortable, while the cushion provides excellent support for your body.

The chair’s ergonomic features, including the adjustable headrest and lumbar support, contribute to its overall comfort.

These features allow you to adjust the chair to fit your body perfectly, ensuring a comfortable and supportive seating experience.
