What makes Cliff 1 ergonomic

The main difference compared to cheap office chairs is the synchronous mechanism – the seat and backrest tilt together in a ratio that mimics the natural movement of the spine. The rocking can be locked in three positions, so you can even take a short break during your lunch break. The forward and backward seat slide is a feature you rarely see at this price point – taller people will benefit the most from it, as the seat extends further under their knees.

The mesh backrest with height-adjustable lumbar support won’t unpleasantly stick your shirt to your body in the summer. The 3D armrests are adjustable in height, sideways, and angularly, a range that places Cliff 1 higher than most competitors around three thousand. The gas lift is class 4, the highest certified category. The 136 kg load capacity is suitable even for taller and more robust figures.

Where it falls short

The main complaint from reviews: assembly can be troublesome. Some users report holes where a screw doesn’t fit, or armrests that are held by only three out of four screws. This is not a rule, but it’s good to know that quality control sometimes lags behind for the price. The second recurring point – the gas lift sometimes “creeps” up even without you, so you have to push the chair down once in a while. It’s not a deal-breaker, but it’s worth mentioning.

Do you invest in an ergonomic chair, or is anything enough for you?
