This ergonomic office chair at €169.99 does what €400 chairs do... and it's hard to understand why it costs so little

The distinguishing feature of the B100 compared to competitors in the same price range is its dynamic lumbar support system with dual elastic backrest. This is not just a simple fixed lumbar cushion, which is a solution often found on cheap office chairs, but rather a structure that adapts to the natural movements of the back in real-time. Whether leaning forward to read a screen or reclining backward during a call, the backrest follows the body without forcing it into a rigid posture. During long work sessions, the difference is noticeable.

The three preset recline angles – 110°, 123°, and 135° – cover various uses: focused work, break during a meeting, complete rest. The adjustable headrest on two axes (height and depth) provides neck support regardless of the chosen position. The flip-up armrests, which follow the seat's inclination, fold under the desk when not needed, a particularly useful detail for those working in tight spaces or with an advanced mechanical keyboard.

The fabric also does not disappoint. The double-layer breathable mesh ensures constant air circulation, eliminating that annoying heat build-up that makes cushioned seats uncomfortable after half an hour. The wider-than-average seat distributes weight better on thighs and pelvis, while reducing pressure points during prolonged sessions. The reinforced steel frame with a five-star base supports a maximum load of 136 kg, and the tilt mechanism, as well as the silent polyurethane wheels, are completely noiseless: no squeaking, no background noise during video calls.

From a technical standpoint, the B100 features a class 3 pneumatic piston for height adjustment, wheels compatible with parquet, ceramic, and carpet, and is available in white in the footrest-free version. The warranty is three years with free returns within 30 days and guaranteed assistance with a response within 24 hours, conditions rarely found under €200.

At €169.99 on Amazon, the SIHOO B100 is one of the few affordable ergonomic chairs in this range that truly justifies its price without resorting to obvious compromises.
