It is support that moves with you, not against you.Need a break? Pull out the smooth footrest, lean back, and suddenly your office chair becomes your personal escape.

The 4D flip-up armrests give you total control over your posture. Adjust them up, down, forward, backward, or rotate them to fit your frame.

Three recline angles let you switch from focused work to full-on lounge mode in seconds.The 3D ultra-wide headrest adjusts to support your neck naturally so your shoulders stay relaxed during long calls or typing marathons. The plush widened seat cushion spreads your weight evenly so there is no more shifting around after a few hours.

That's it, chair finally assembled! It takes about an hour to assemble, which is a bit long, but the result is well worth it. This chair is very comfortable: it is made of woven polyurethane, a slightly plasticized but soft material, which makes the seat, backrest and headrest pleasant. The big highlight is that it is fully ventilated, without conventional padding. The stretched canvas is self-sufficient, which should be much more pleasant in summer, without the sticky effect as with faux leather. Moreover, coming from an old faux leather chair that peeled off over time, I think this model will be more durable. On the practical side, the armrests are swivel and can be raised completely; this allows the chair to be slid under the desk, even with constraints such as a drawer There are a few points to improve, however: ? no adjustment of the backrest (impossible to get into a more lying position) ? adjustment of the headrest quite hard ? to adjust the height of the seat, you have to stand up completely, which is not very practical Despite these small flaws, The chair is comfortable and a good improvement compared to my old model.

I installed this office chair to replace my old worn chair, spending quite a few hours in front of my screen working from home. The level of settings on this model is really excellent. The dynamic lumbar support follows back movements well, and the multi-directional adjustable armrests allow you to find the perfect position to relieve the shoulders. The stretched fabric is also very breathable. However, editing required a bit of time and organization. The chair is quite heavy when assembled, which proves its overall strength, but makes it a bit difficult to move on a floor equipped with thick carpeting. It is a very qualitative investment, which will delight those looking for real support and correct posture during long sessions in the office.

This chair is very comfortable. If you have a chair purchased in a Swedish furniture store, please leave, change, your back will thank you for it. The chair itself can be assembled without much difficulty, and is very comfortable, with good lumbar support and a headrest that I can use despite my large size. The thing I like the most is the fact that I can almost lie on them, which makes it easier for my cat to sleep on his favorite cushion (me, while I work) The only downside is that the armrests are a bit hard and could be more stable, but personally I don't use them because I have a corner desk, they are usually raised. So other than that, I highly recommend it.
