Review is for the ProtoArc Ergonomic Office Chair for Home Office, High Back Desk Chair with Thick Spring Cushion, Adjustable Headrest, Armrests, Big and Tall Mesh Computer Chairs for Long Hours Sitting - BlackMy wife and I both work remotely, and my children all use office type chairs in their bedrooms, so I have experience with these kinds of chairs.To start, this was extremely well packaged. I only mention that because it was the first indication of the quality put into this chair. Other chairs I've ordered have not been as well packed to ensure no damage during transportation.Assembly was very easy assembly, with clear instructions and everything needed to assemble including tools for tightening the screws, as well as additional screws in the event you lose some in future. I doubt it though, as the screws were coated with a loc-tite compound.The chair is very comfortable, and not too stiff. I like the breathable mesh backing which helps keep me cool while I'm working.The adjustment options are typical for an office chair to help make it ergonomically comfortable. Armrests raise up/down/front/back and swivel. The chair height is easily adjustable up/down with a lever on the side. The back can be locked in an upright position, or you can unlock it and recline back to about 130 degrees.The lumbar support is non-adjustable but it's positioned well for my use.The next support is adjustable, both in angle and in height.Overall this is a solid, well made chair that I anticipate will last a long time. I've found no reason to deduct any stars.

I watched a video review that I swore was the same product, but it appears to just look identical. You can’t lock the mechanism for the back, you can only have it locked straight up, or unlock it and just lean back, and it takes effort to push it backwards. (Like a rocking chair) The piece that goes behind your lower back was uncomfortable, I ended up removing it and putting a small blanket there instead so my back doesn’t touch the plastic. Also you can’t rotate the arm rests, which was disappointing. The seat cushion is nice, though. Not exactly the product I hoped for, but it’s better than the broken chair I was using.

Had the chair for a few weeks now and I’m very impressed. As others have mentioned - it is very hard to beat at this price. Comfortable and well made. Assembly was very straightforward. Highly recommended.

I ordered one of these chairs a few days ago and was delivered in good order without tears in the box, good quality box. Was able to put it together in 25 minutes without issue, good instructions provided. Quality is good, thick plastic on the bend point between seat and back, great lumbar support as I'm 6' 1" at 165lbs.. Very comfortable seat, much better than my previous mesh seat as it appears weight is more equally distributed. Only disadvantage is that there are only two locking positions for the back, one for straight up and one for fully reclined. For the price you cannot find a better value for an ergonomic chair. I work in this chair about 12 hours a day and I can tell you my back feels 400% better. I have ordered a second chair for my daughter whom is 5' 3" at 110lbs and also fits her perfectly.

I really like the overall quality of this chair.I do recommend watching the video before putting it together. Everything is well marked but can get confusing.The only option I found lacking was a forward tilt adjustment on the chair back. Other than that, very happy.

Ho preso questa sedia per poter lavorare in Smart, nel complesso l'ho scelta per il supporto lombare e cervicale che attenuano la fatica nello stare seduti tante ore davanti ad uno schermo. Tra i pregi che ho notato:- Facilità nel montaggio.- Robustezza e qualità dei materiali.- Supporto cervicale regolabile sia in altezza che inclinazione.- Regolazione dei poggia-bracci in altezza.L'unica cosa che mi ha fatto storcere il naso é stata la guida utente per il montaggio, due passaggi son poco chiari e se non si fa attenzione si rischia di invertire alcuni processi di montaggio.L'azienda ha messo delle indicazioni su come montare i particolari ma "Curve side" può voler dire tutto o niente, metterei (é un consiglio, accettabile o meno) anche solo una breve etichetta di riconoscimento del verso sotto la sedia con l'aggiornamento della guida utente, in modo che possa orientarsi (per farvi capire nel passaggio che ho trovato difficoltoso non c'era nell'immagine guida l'orientamento rispetto ai fori M.6/M.8).Per il resto super soddisfatto! (anche della spedizione, ho ricevuto l'articolo nel giorno previsto senza ritardi):

Solidly built and comfortable. This chair is supportive, adjustable in all the right places, and is easy to work with.The gray and black combination match my office theme and present a clean, professional look on and off camera.I’ve had a lot of chairs. This one is not too heavy or too light. It’s comfortable enough to last the day and I don’t dread sitting down. Although mine is paired with a standing desk for variety. Still can’t sit all day, but if I were to, this would be the right chair for the job.

I am 5'6 and the lumbar support is too low and is not adjustable like other chairs. Could be more comfortable if the lumbar hit where I need support. Caution if this is what you are looking for.
