For maximum PC comfort: A more premium office chair from Alza is on sale, Czechs praise it

Looking for a new office chair for maximum comfort at your computer? The AlzaErgo Chair Abyss 2 has now dropped from 11,990 CZK to 8,393 CZK, which is the lowest price since the January sales. It boasts a synchronous mechanism, 4D armrests, lumbar support, and a height-adjustable headrest. Plus, it has excellent ratings.

Quick summary:
✅ Makes sense if you spend 6+ hours a day at your computer and are looking for a chair with extensive adjustability at a reasonable price.
⚠️ Consider if you are over 185 cm tall or need depth-adjustable lumbar support.
💡 For 8,393 CZK you get a synchronous mechanism, a metal base, and HR foam – parameters that often mean a price tag over 12,000 CZK from competitors.

Why this chair is interesting

The AlzaErgo Abyss 2 targets people who need all-day back support without compromise but don’t want to pay 15–20 thousand for premium brands like Herman Miller or Secretlab. In practice, you get a synchronous mechanism (the seat moves together with the backrest), a height-adjustable backrest with integrated lumbar support, and the option to lock it at several angles. These are features you simply won’t find in cheaper chairs costing 3–5 thousand.

When launched, the chair cost 11,990 CZK. Promotions gradually appeared, with the historical minimum being in January 2026, when it could be purchased for 7,990 CZK. The current 8,393 CZK is therefore the second lowest price ever – and significantly better than the usual 9–10 thousand outside of promotions.

What you can actually adjust

The main advantage of Abyss 2 is its range of adjustability. The seat height can be changed within the range of 47.5–57 cm, and the seat depth can be moved forwards or backwards according to thigh length. The backrest is height-adjustable and can be locked at various recline angles (90–135°). The headrest can be tilted in two axes and adjusted vertically.

Područky jsou označované jako 4D – nastavíte je výškově, do stran, dopředu/dozadu i úhlově. V praxi to znamená, že si je můžete přizpůsobit tak, aby vám ruce při psaní ležely přirozeně. Sedák tvoří HR pěna (za studena tvarovaná), která drží tvar lépe než běžná PUR pěna a podle recenzí zůstává pohodlná i po měsících používání.

Practical aspects: construction, wheels, assembly

The chair’s base consists of a robust metal cross base with integrated footrests – a detail you won’t find on cheaper plastic bases. The weight capacity is 130 kg, and the recommended user height is 160–190 cm. The backrest is made of mesh, which you’ll appreciate in summer – air circulates, and you won’t sweat as much as on a leatherette backrest.

The package includes hard wheels primarily designed for carpets. If you have laminate flooring or tiles, they also work, but for maximum floor protection, it’s worth buying soft wheels (for example, AlzaErgo Castor SC60 for less than two hundred CZK). According to reviews, assembly takes 10–15 minutes – just screw in two screws, and the rest clicks into place.

What users say

On Alza, the chair has a rating of 4.5 out of 5 (136 ratings) and 87% of customers recommend it. Over 2,000 units have been sold with a low complaint rate (1.23%). Most often, people praise the seat comfort, easy assembly, and amount of adjustability. Several reviewers mention that back pain disappeared after switching from a cheap chair or gaming chair.

Critical voices mainly appear regarding details. The armrests do not have a lock – they sometimes shift when leaning on them, which bothers some users. The lumbar support cannot be adjusted in depth, so if you have a flatter back, it might feel too prominent. Several reviewers over 185 cm tall state that the backrest is not high enough for them. And a few people reported that the headrest occasionally slides out of its set position.

When it doesn’t make sense

If you are significantly taller than 185 cm or have a long torso, the chair might feel cramped – in such a case, it’s worth looking for models with a higher backrest. Similarly, if you have specific requirements for lumbar support (e.g., due to health problems), the lack of depth adjustment can be limiting. And if you only sit at the computer for an hour a day, investing in an ergonomic chair for 8 thousand CZK is probably not necessary.

Verdict: who it’s worth it for

If you are looking for an ergonomic chair for all-day work and don’t want to exceed the 10,000 CZK mark, the Abyss 2 for 8,393 CZK offers one of the best price/performance ratios on the Czech market. A synchronous mechanism, metal base, HR foam, and extensive adjustability – these are parameters that often mean a significantly higher price tag from competitors. Conversely, if you need maximum variability in lumbar support or are taller than 185 cm, consider alternatives.
