Office chair with mesh and 3D armrests now costs only 4,199 CZK. It has solid ratings

A quality office chair doesn’t have to cost more than five thousand. Proof of this is the model AlzaErgo Chair Dune 1, which is now available for 4,199 CZK. Before the promotion, it cost 4,839 CZK, and in the past, it was long priced at 6,490 CZK. It features a mesh backrest, 3D armrests, and solid user ratings.

Quick summary:
✅ Makes sense if you are looking for a chair for all-day work with a breathable backrest, adjustable armrests, and lumbar support.
⚠️ Consider if you are under 165 cm or over 190 cm tall – the headrest might not fit ideally.
💡 For 4,199 CZK you get a synchronous mechanism and 3D armrests, which is usually found in a higher price category among competitors.

Why this chair is interesting

AlzaErgo Chair Dune 1 targets people who spend several hours a day at the computer and don’t want to pay double for an ergonomic chair. The main advantage is the synchronous mechanism – when rocking, the seat and backrest move together, which supports active sitting and protects the spine. In combination with a breathable mesh backrest and adjustable lumbar support, this is equipment you often won’t find in cheaper chairs.

What you can adjust

The chair offers quite wide customization options. The 3D armrests can be adjusted in height, sideways, and angularly – this will be appreciated by anyone who needs forearm support while typing. The lumbar support moves vertically (range 53–71 cm from the ground), so you can adjust it precisely to your lower back area. The headrest is also adjustable in height and angle, although some users point out that it might still be too high for individuals under 170 cm.

The backrest tilt can be locked in the range of 95–115°, and the rocking resistance is automatically adjusted according to your weight. The seat height ranges between 47–59 cm, which covers most body types within the recommended range of 160–190 cm.

Seat and materials

The seat measures 51 × 48 cm and is filled with high-density PU foam. The fabric cover is pleasant to the touch and easy to clean. However, some users report after prolonged use (six months or more) that the foam may flatten – which is relatively common in this price category.

The backrest is made of mesh on a nylon frame, so it remains breathable even in summer. The plastic base with hard 60 mm diameter wheels is primarily designed for carpets – if you have a hard floor, we recommend purchasing soft wheels.

What users say

On Alza, the chair has a rating of 4.3 out of 5 (74 ratings) and 80% of customers recommend it. Over 2,000 units have been sold with a very low complaint rate (0.57%). Most often, people praise the price/performance ratio, comfortable mesh backrest, and easy assembly – most can manage it within 15 minutes.

However, reservations also repeatedly appear. Several reviewers mention stiff rocking, which may not suit everyone. Others point out that the headrest is too high for shorter individuals – if you are around 160 cm tall, it will likely be behind your crown instead of under it. A few users reported squeaking, but this usually disappears after tightening the screws. And one reviewer mentioned that the piston started to sink just after the warranty expired – a replacement part is not commonly available.

When it doesn’t make sense

If you are under 165 cm or over 190 cm tall, the headrest will likely not fit ideally. The chair does not have adjustable seat depth or forward/backward backrest movement, so it cannot be adapted to extreme body types. Also, if you prefer soft rocking or need to adjust the armrests completely close to your body, you might encounter construction limitations.

Verdict: who it’s worth it for

If you are looking for an ergonomic chair under 5,000 CZK with a breathable backrest, synchronous mechanism, and 3D armrests, the AlzaErgo Chair Dune 1 for 4,199 CZK is a solid choice. It fits individuals between 165–185 cm well, the 130 kg weight capacity handles most users, and assembly is quick. However, be aware that after a year of intensive use, the seat may slightly flatten, and the headrest is not universal.
