SIHOO vs COMHOMA Chair Specs
Upholstery Material
The SIHOO M18 uses a breathable mesh backrest designed to keep your back cool during long sessions. This fabric allows for airflow, which helps maintain comfort when you are sitting for hours. In contrast, the COMHOMA chair features PU leather upholstery. This material offers a smooth, sofa-like surface that is easy to wipe clean. Leather often retains heat more than mesh, so the SIHOO may feel cooler in warm rooms. The COMHOMA provides a more traditional, padded look, while the SIHOO prioritizes ventilation. You should choose based on whether you prefer airflow or a sleek, leather finish.
Weight Capacity
Support limits are critical for durability and safety. The SIHOO M18 is rated to support up to 150kg. It has passed BIFMA tests and a 1136kg static pressure test, indicating a robust frame for general office use. The COMHOMA chair is marketed as a Big and Tall model, but the specific weight capacity is not listed in the provided specifications. However, its designation as heavy-duty and its use of pocket springs suggest it is built for larger users. Without a explicit number for the COMHOMA, the SIHOO offers a clear, verified limit. If you are under 150kg, the SIHOO provides documented proof of its strength.
Armrest Adjustability
Armrests help reduce shoulder strain by supporting your arms at the right height. The COMHOMA chair explicitly features height-adjustable armrests. This allows you to raise or lower them to match your desk height or body type. The SIHOO M18 data does not specify the adjustability of its armrests, listing only a headrest as a primary feature. This lack of detail means you cannot confirm if the SIHOO arms move up and down. The COMHOMA gives you a clear advantage here if you need to customize your arm support height for different tasks or body sizes.
Lumbar Support Type
Lower back support is essential for preventing pain during long sitting periods. The SIHOO M18 provides dedicated lumbar support as part of its four-point ergonomic design. This system targets the head, back, hips, and hands to reduce pain. The COMHOMA chair uses built-in pocket springs in the lumbar area. These springs are designed to offer elastic support that conforms to your back shape. While both offer support, the methods differ. The SIHOO uses a structured ergonomic approach, while the COMHOMA relies on spring mechanics. The SIHOO explicitly mentions reducing pain, whereas the COMHOMA focuses on gentle, conforming support.
Additional Features
Extra features can change how you use the chair. The COMHOMA includes an integrated footrest and a tilt function. The footrest allows you to elevate your legs, which can improve circulation and relaxation during breaks. The SIHOO M18 does not list a footrest or a specific tilt mechanism in its key specs. It focuses on height adjustment and lumbar support instead. If you plan to recline or rest your legs frequently, the COMHOMA offers more versatility. The SIHOO is simpler, focusing on upright ergonomic support without the added complexity of a footrest.
Seat Dimensions
Seat size affects comfort for different body types. The COMHOMA is described as having a spacious seat and a wider backrest, suitable for crossing legs or bending. It is labeled as Big and Tall. The SIHOO M18 has a seat width of 21 inches. The COMHOMA has a width of 22 inches. While both are standard widths, the COMHOMA’s marketing emphasizes a generous, sofa-like space. The SIHOO is suitable for people 5'6" to 6'2" tall. The COMHOMA does not list a height range, but its larger designation suggests it accommodates bigger frames more comfortably than the standard SIHOO model.

The thick padding and elastic seat surface provide sofa-like comfort. With height-adjustable armrests and built-in pocket springs for lumbar support, it offers solid support for larger body types who need more seating area.
Users who want a built-in footrest
The COMHOMA model includes an integrated footrest, allowing you to relax your legs while seated. This feature adds versatility for napping or resting during breaks. Combined with a reclining function and PU leather upholstery, it provides a cozy experience.
