AlzaErgo Chair Abyss 2: A Comprehensive Review

Are you looking for a new office chair for maximum comfort while working at your computer? The AlzaErgo Chair Abyss 2 has recently been available for 8,393 CZK, a competitive price point. It features a synchronous mechanism, 4D armrests, lumbar support, and a height-adjustable headrest, and boasts positive user ratings.

Quick Summary

The AlzaErgo Chair Abyss 2 is a sensible choice if you spend 6+ hours a day at your computer and are looking for a chair with ample settings at a reasonable price. Consider alternatives if you are taller than 185 cm or require a depth-adjustable lumbar support. For 8,393 CZK, you get a synchronous mechanism, a metal cross, and HR foam – features often found in chairs priced over 12,000 CZK from competitors.

Why is this Chair Interesting?

The AlzaErgo Abyss 2 targets individuals who need all-day back support without the premium price tag of brands like Herman Miller or Secretlab. It offers a synchronous mechanism (where the seat and backrest move in coordination), a height-adjustable backrest with integrated lumbar support, and multiple angle locking positions. These features are typically absent in cheaper chairs.

Price History

The chair originally launched at 11,990 CZK. Promotions have been frequent, with a historical low of 7,990 CZK in January 2026. The current price of 8,393 CZK is the second-lowest ever offered, significantly better than typical sale prices.

What Adjustments Can You Make?

The primary advantage of the Abyss 2 is its range of adjustability. The seat height is adjustable between 47.5 and 57 cm, and the seat depth can be moved forward or backward to accommodate different thigh lengths. The backrest is height-adjustable and can be locked at various inclination angles (90–135°). The headrest is adjustable in two axes and height.

The armrests are 4D adjustable – height, sideways, forward/backward, and angularly – allowing you to position them for natural hand placement while typing. The seat is constructed with HR foam (cold-formed), which maintains its shape better than standard PUR foam and is reported to remain comfortable even after extended use.

Construction, Wheels, and Assembly

The chair’s base is a sturdy metal cross with integrated footrests, a feature not commonly found on cheaper plastic bases. It has a weight capacity of 130 kg, and the recommended user height is 160–190 cm. The backrest is made of mesh, providing airflow and reducing sweating.

The package includes hard wheels designed for carpets. While they can be used on hard floors, soft wheels (such as the AlzaErgo Castor SC60) are recommended for floor protection. Assembly is reported to take approximately 10-15 minutes, requiring only the screwing in of a few components.

What Users Are Saying

On Alza, the chair has a rating of 4.5 out of 5 stars (based on 136 ratings), with 87% of customers recommending it. Over 2,000 units have been sold with a low complaint rate (1.23%). Customers frequently praise the seat comfort, easy assembly, and adjustability. Several reviewers have noted a reduction in back pain after switching from cheaper chairs.

Common criticisms include the lack of armrest locking – some users experience shifting when leaning – and the non-adjustable lumbar support depth. A few users over 185 cm tall find the backrest too short. Some reviewers have also reported occasional headrest slippage.

When Might This Chair Not Be the Right Choice?

If you are taller than 185 cm or have a long torso, the chair may feel restrictive. If you have specific lumbar support requirements, the lack of depth adjustment could be a limitation. If you only spend an hour or less a day at the computer, investing in an ergonomic chair may not be necessary.

Verdict

If you are seeking an ergonomic chair for all-day work and want to stay under 10,000 CZK, the Abyss 2 for 8,393 CZK offers a strong price-to-performance ratio. The synchronous mechanism, metal cross, HR foam, and extensive adjustment options are typically found in more expensive models. However, if you need highly adjustable lumbar support or are over 185 cm tall, consider alternative options.
