Do your back hurt from the computer? Alza is selling out a great ergonomic chair for 9 thousand

If you spend six or more hours a day at the computer and are starting to feel back pain, Alza.cz is currently offering the AlzaErgo Chair Abyss 2 for 8,993 CZK with discount code ALZADNY25. The original price was 11,990 CZK, so the discount is 25%. It is an ergonomic office chair with a synchronous mechanism, lumbar support, and mesh back, which has a rating of 4.5/5 stars from 98 customers on Alza, and 88% of them recommend it. But – and this is important – it also has several recurring issues that appear in reviews.

What you get for 9 thousand: synchronous mechanism and lumbar support

The AlzaErgo Chair Abyss 2 is an ergonomic chair with a synchronous mechanism – meaning that the seat and backrest move dependently on each other when rocking. Practically, it looks like this: when you lean back, the seat slightly moves forward to keep your thighs in an an optimal position. This is a different principle than with cheaper chairs, where only the backrest rocks and the seat remains static.

The chair has a height-adjustable mesh backrest (70 cm high) that ensures airflow – in summer, you’ll appreciate that your back doesn’t sweat. The lumbar support is integrated and very prominent – according to reviews, “as if I threw a beer belly on my back.” Some people find it comfortable (praising it for supporting correct posture), while others do not (it pushes them too much into a forward lean).

The seat has dimensions of 50 × 43 cm, is filled with HR foam (High Resilience foam), and can be moved forwards/backwards, which is useful for adjusting to thigh length. The seat height is adjustable within the range of 47.5–57 cm using a gas lift. The weight capacity is up to 130 kg, and the recommended user height is 160–190 cm.

Real-world experiences: praise and criticism

Out of 98 reviews on Alza, 88% are positive, but similar problems recur. The most frequent complaint concerns the armrests – they are 4D adjustable (height, sideways, forwards/backwards, and angularly), but they lack a locking mechanism. Practically, this means that when you lean on them with your palms (e.g., to move in the chair), they shift. One reviewer writes: “The armrests move forwards, backwards, sideways… several times a day.”

Another common problem is the backrest locking mechanism. It adjusts to three height positions, but when it slides to the highest position, it automatically unlocks and falls back down. Another customer from Žandov writes: “When you shift in the chair and hit the lumbar support with your backside, the backrest drops three notches down. I adjust it about once a day.”

The third recurring issue is the seat depth. For people with a height of 160–180 cm, the seat is fine, but those who are 185 cm and taller write that they would appreciate a longer seat. Jakub from Olomouc (height 180 cm+) recommends “individuals 180 cm+ to look elsewhere.”

On the other hand – reviews praise comfort, especially after switching from cheaper IKEA-type chairs. Jiří from Odolena Voda writes: “This is a completely different level than the original IKEA chair. You sit on it like a king on a throne.” Radovan from Štěchovice adds: “I no longer have back pain after long hours of sitting at the computer, so it perfectly fulfills its ergonomic purpose.”

Who is the chair suitable for?

The AlzaErgo Chair Abyss 2 makes sense for people who spend 6+ hours a day at the computer and need an ergonomic chair with lumbar support. If you are 160–180 cm tall, the seat should fit you. If you are 185 cm or taller, you might find the seat shorter than you’d like.

The lumbar support is very prominent – if you have problems with slouching or weak lumbar muscles, this chair will force you to sit straight.

If you are bothered by the armrests moving without a locking mechanism, try to get used to it or look for another chair. Some reviewers write that they got used to it in a week and no longer notice it, while others solve it by not leaning on the armrests with their palms.

Comparison with competition: Herman Miller, Liftor

For 9 thousand CZK, the AlzaErgo Chair Abyss 2 offers very good value for money. An anonymous reviewer writes: “Better chair than the previous one for 600+ €” (over 15,000 CZK). Another adds: “For that price, it’s an excellent chair; similar ones cost around 15 thousand.”

If you wanted an even better chair, you would have to opt for a Herman Miller Aeron (from 35,000 CZK) or Steelcase Gesture (from 40,000 CZK). Nikola from Vyžlovka writes: “It rivals Herman Miller” – which is, of course, an exaggeration, but for a fraction of the price, it’s a solid alternative.

Verdict: solid ergonomics for 9 thousand with compromises

For 8,993 CZK with discount code ALZADNY25, the AlzaErgo Chair Abyss 2 offers good value for money for people 160–180 cm tall who spend long hours at the computer and need an ergonomic chair. A synchronous mechanism, lumbar support, and mesh back are features you won’t find in chairs costing 5,000 CZK.

But – and this is important – the chair also has weaknesses. The armrests move without a locking mechanism, the backrest has a problem with its locking mechanism, and the lumbar support is very prominent (some find it comfortable, others do not). If you are 185 cm or taller, the seat will likely be shorter than you’d like.

If you are willing to live with these compromises, for 9 thousand, you will get a chair whose quality approaches models costing 15,000 CZK. The offer is valid with discount code ALZADNY25 on Alza.cz. Alza has a low complaint rate of only 1.23%, which is a solid number.
