Why this chair is interesting

This AlzaErgo Chair Delta 1 Plus chair is aimed at people who spend all day at the computer and want to literally adjust every part of the chair to their liking. It primarily attracts with its huge range of adjustments: a sliding seat, height-adjustable backrest, lumbar and head support, and especially magic armrests adjustable in all directions. In addition, a breathable mesh backrest, which is especially appreciated in warmer months. For 6 293 Kč with code 30ALZAERGO2026, it’s an affordable way to get a fully adjustable ergonomic chair.

Key parameters in plain language

The core is a synchronous mechanism, where the seat and backrest move in unison to support dynamic sitting, plus premium cable control for a cleaner look. The backrest tilts from 94° to 120° with four-position locking and has seven height positions. The weight capacity is 130 kg, and the manufacturer states suitability for users 160–190 cm – however, according to reviews, the chair is more suitable for taller individuals (approximately 180 cm and up); shorter people may have trouble comfortably reaching the ground and fully utilizing the adjustments.

Practical aspects: assembly, seat, supports

According to users, assembly takes about 15 minutes and everything needed is included in the package; only the final attachment of the heavy backrest would benefit from a second person’s help. The seat is sliding and filled with high-density PU foam, allowing depth adjustment, and according to reviews, it is large and comfortable, especially for taller and more robust individuals. The 60 mm diameter wheels are quiet on both hard floors and carpets. It’s also pleasant that the magic armrests can be adjusted to practically any position – though with one “but,” which we’ll get to.

Two things need to be said upfront. Firstly, the chair has a slightly reclined sitting position – the backrest does not go to a perpendicular 90°, the basic position is 94°, which suits some, while others would prefer a more upright posture. Secondly, the lumbar support has only two positions, and its height is tied to the height of the entire backrest, so it cannot be adjusted independently, and for some people, it presses into their back. Those sensitive to specific lumbar adjustments should keep this in mind.

What users say

Honesty is required here: the rating is 4.1 out of 5 from 48 customers and 71% of buyers recommend it – which is less than many other chairs, and opinions vary significantly. Satisfied users, often taller individuals, praise the huge range of adjustments, large comfortable seat, and breathable backrest and consider the chair an excellent value for money when on sale. Several people call it the best they have ever sat on.

However, critical voices appear repeatedly, and it’s fair to mention them. The most common complaint is wobbling and play in the backrest, which many people describe shortly after assembly – for some, the backrest “wobbles by a centimeter.” Several users mention squeaking after a few weeks (solvable by lubrication), some are bothered by the extensive use of plastic and armrests that cannot be locked and thus easily rotate. Occasionally, there was also a problem with the piston; however, the complaint rate is low (0.62%), so it’s more about individual units.

When it doesn’t make sense

If you are shorter (significantly under 175 cm), the chair might not suit you – many adjustments are designed more for taller people. Anyone who wants an absolutely firm, non-squeaking backrest without the slightest play should, based on user experiences, consider a more expensive model or try the chair in person. And if you need an upright sitting position precisely at 90° or fine independent lumbar adjustment, this design won’t provide it. Under these conditions, it makes sense to opt for a different chair.

Verdict: who it’s worth it for

If you are taller and looking for a maximally adjustable ergonomic chair with a breathable backrest for a reasonable price, the AlzaErgo Chair Delta 1 Plus for 6 293 Kč is a justifiable purchase – especially for the saving of 2 697 Kč compared to 8 990 Kč and with a three-year warranty. However, I won’t hide anything: the rating of 4.1 out of 5 reflects that some users are bothered by the backrest wobbling, slight recline, and lumbar support. For a taller person who appreciates the range of adjustments and doesn’t mind a slight play in the back, it’s a good buy at this price. Anyone who wants a premium feel and absolute rigidity should consider a more expensive alternative, ideally after trying it in person.

What is more important to you in an office chair – range of adjustment, or maximum rigidity and firmness?
