2. Lumbar Mechanics & Pressure Contact Mapping
The backrest performance in our Sihoo M18 vs Ticova Ergonomic Office Chair evaluation is determined by how effectively it maintains the spine’s natural lordotic curve without creating localized pain points.

Ticova: Active Lordotic Engagement
The Ticova backrest incorporates an independent, plastic-framed lumbar bolster lined with dense foam padding. It provides 1.6 inches of vertical travel and 1.4 inches of depth adjustment via a rear dial knob.
Pressure Mapping Data: Under tactile grid testing with Tester B (212 lbs), setting the Ticova lumbar dial to maximum depth achieved an 84% total lumbar contact coverage area. The pad applies focused forward pressure directly against the L1–L5 vertebrae. For sitters prone to slouching, this active push forcibly prevents pelvic tilt. However, for Tester A (145 lbs), maximum depth caused peak pressure concentrations above 12 kPa, requiring the dial to be backed off to minimum depth for multi-hour comfort.
Sihoo M18: Passive Posture Cradle
The Sihoo M18 employs a broader lumbar pad with thinner foam cushioning, adjusting 1.9 inches vertically and 0.8 inches in depth.
Pressure Mapping Data: Under identical load conditions, the Sihoo M18 registered a 62% total lumbar contact coverage area. Rather than pushing forcefully into the spine, the pad provides a gentle boundary wall that cradles the lower back. It feels less intrusive out of the box, making it better suited for sitters who dislike firm lumbar prompts.
3. Seat Cushion Engineering & Foam Density
Long-shift comfort in the Sihoo M18 vs Ticova Ergonomic Office Chair review depends heavily on seat pan foam composition and thigh clearance profile.
Ticova: 3.4-Inch Molded Foam Pan
The Ticova seat pan utilizes a 3.4-inch thick cold-molded polyurethane foam core encased in breathable mesh fabric. Molded foam features a high-density cell structure that resists permanent deformation.
Compression Test Result: Under a continuous 8-hour static load of 212 lbs, the Ticova seat pan compressed by 1.1 inches, leaving 2.3 inches of active cushion clearance above the base frame. The steep waterfall front edge relieved popliteal pressure behind the knees effectively.
Sihoo M18: W-Shaped Cut Sponge Pan
The Sihoo M18 uses a high-density cut sponge cushion formed into a contoured W-shaped saddle profile, wrapped in woven upholstery fabric.
Compression Test Result: Under the same 212 lbs static load, the softer sponge compressed by 1.7 inches. While lighter sitters (<180 lbs) praised the plush initial saddle feel, heavier sitters experienced noticeable firmness breakdown near the end of an 8-hour work shift.
4. Armrest Mechanics & Wobble Tolerance
Armrest functionality directly affects upper trapezius and wrist ergonomics during desktop typing and peripheral use.
- Ticova 3D Armrests: Feature 2.8 inches of vertical height, 2.4 inches of forward/backward slide depth, and 40 degrees of rotational pivot (20° inward / 20° outward). The inward pivot angle allows elbows to stay closer to the torso when typing on compact keyboards or holding mobile devices. Trade-off: Due to the multiple internal sliding joints, the armrest caps exhibit 3.5 mm of lateral mechanical wobble when shaken.
- Sihoo M18 2D Armrests: Offer 2.8 inches of vertical height adjustment only. Lacking sliding depth and rotational pivot mechanisms, the arm structures feel substantially sturdier, exhibiting less than 1.0 mm of mechanical wobble.
5. Recline Dynamics & Neck Support
| Feature | Ticova Ergonomic Chair | Sihoo M18 Office Chair |
|---|---|---|
| Max Recline Angle | 130 Degrees (Deep relaxation profile) | 126 Degrees (Standard task profile) |
| Tilt Lock Positions | 3 Locked Positions (90°, 110°, 130°) | 3 Locked Positions (90°, 108°, 126°) |
| Headrest Surface Area | Large, deeply curved mesh pad | Compact, flat-curved mesh pad |
| Cervical Support Alignment | Excellent for sitters 5’5″ to 6’1″ | Optimal for sitters 5’6″ to 5’11” |
