Alternatives to the Sihoo M 18
Although the Sihoo M 18 is a good and affordable office chair, it is worth considering possible alternatives.
Alternative 1: ERGOMY
At under 150 € the hjh OFFICE ERGOMY is an alternative that is more affordable while still offering high ergonomic standards fulfilled. This entry-level chair features 3D armrests with 8-level height adjustment and the option to adjust them radially and vertically. The lumbar support is depth-adjustable, promoting a healthy sitting posture. At the same time, the height-adjustable headrest relieves strain on the neck and head area. It also comes with a comfort synchro mechanism for synchronised adjustment of the seat and backrest tilt, with spring tension that can be adapted to the user's individual body weight. The load-dependent braked safety castors ensure stable positioning and prevent the chair from rolling away unintentionally when not under load. At the same time, the ERGOMY is not only functional and ergonomic, but also visually appealing in any workspace.

Alternative 2: VENUS BASE
The hjh OFFICE office chair VENUS BASE is described as a design highlight with incredible technical refinements .

The flexible lumbar support and the height-adjustable backrest allow you to tailor it perfectly to your individual needs. At a price of 399,99 € (as of 9/24), it is a little more expensive than the Sihoo M 18, but in return offers more ergonomic features and is therefore a possible alternative.
