M18 vs B100 Side-by-Side
Weight Capacity
The SIHOO B100 supports up to 300 lbs, while the M18 is rated for 150 kg, which converts to approximately 330 lbs. Both chairs use robust construction to handle daily use, but the M18 has a higher numerical limit in the provided data. The B100 relies on a Class 4 gas lift and SGS certification for stability. The M18 passed the BIFMA test and a 1136kg static pressure test. If you need maximum load bearing, the M18 offers a slight edge in stated capacity.
Lumbar Support Type
Lumbar support differs significantly between these two models. The B100 features dynamic lumbar support that moves with your spine, adapting as you lean forward or shift posture. This is designed to keep your back supported without feeling stiff. The M18 provides standard lumbar support and back support adjustment to meet different needs. It offers four support points including head, back, hip, and hands. If you prefer adjustable, moving support, the B100 is the better choice for long sitting sessions.
Recline Functionality
Recline options vary between the two chairs. The B100 offers three lockable angles: 110°, 125°, and 135°. This allows you to switch from work mode to total relaxation or a quick recharge. The M18 data does not list specific recline angles or lockable positions. It focuses on seat height, headrest adjustment, and lumbar support. If you want distinct recline settings for breaks, the B100 provides clear options that the M18 does not specify in its features.
Headrest Adjustability
Both chairs include headrests, but the level of adjustability is not equal. The B100 specifies an adjustable headrest that supports your neck while typing, calling, or leaning back. This ensures balanced support regardless of your posture. The M18 lists a headrest in its features and key specs, but does not explicitly state it is adjustable in the provided text. It mentions headrest adjustment in the general features section, implying adjustability. However, the B100’s explicit description makes it clearer for users needing precise neck support.
Seat Dimensions
Seat size impacts comfort for different body types. The B100 has a width of 28.3 inches, which is wider than the M18’s 21 inches. The B100 also features a widened seat cushion to spread weight evenly across hips and thighs. The M18 is suitable for people 5'6" to 6'2" tall. The B100 seat height adjusts from 18.3" to 21.9". If you prefer a broader seating area for better weight distribution, the B100 offers a more spacious seat than the narrower M18.
Certifications
Safety and durability certifications differ slightly. The B100 meets both SGS and BIFMA standards, with a Class 4 gas lift for stability. The M18 passed the BIFMA test and a 1136kg static pressure test. Both chairs prioritize quality and safety. The B100 includes SGS certification, which may indicate additional testing beyond BIFMA. The M18 highlights its static pressure test results. For buyers who value multiple certification marks, the B100’s dual certification provides a slight advantage in verified standards.
Choose the Right SIHOO Chair
Heavy-duty users needing max capacity
The B100 supports up to 300 lbs. It also features SGS and BIFMA certifications. This model includes a Class 4 gas lift and a reinforced metal base. These specs ensure stability for heavier users. The M18 supports 150 kg, roughly 330 lbs, but the B100 offers additional structural certifications for peace of mind during long sessions.
Users wanting adjustable recline angles
Only the B100 provides three lockable recline angles: 110, 125, and 135 degrees. This allows you to switch between work and relaxation modes. The M18 data does not list specific recline angles or lock positions. If you need to lean back at precise intervals, the B100 offers this functional flexibility for your workflow.
Buyers prioritizing adaptive lumbar support
The B100 features dynamic lumbar support that moves with your spine. This adaptive system adjusts as you lean forward or sit upright. The M18 lists standard lumbar support but does not specify dynamic movement. If you prefer back support that actively follows your posture changes rather than remaining static, the B100 is the better technical choice.
Those seeking a lighter chair option
The M18 weighs 38 pounds, making it heavier than the B100, which weighs 35.5 pounds. However, the M18 is a simpler mechanical design. It passes BIFMA and 1136kg static pressure tests. If you prefer a chair with a straightforward assembly process and do not need dynamic lumbar features, the M18 provides reliable basic ergonomic support.
