Great Chair
This is a great office chair with back and neck support. Easy to assemble if you can follow instructions and have basic understanding of putting things together. Quality materials.

Good build quality, good lumber support.
In my opinion, the chair is designed for working rather than gaming. It doesn’t offer you a feeling on but makes you feel better when working on the table for a long time. It has a discontinuity point between shouder and lumber. Some people will think it is uncomfortable, but it helps your sacral bone in right position that prevent low back pain.

Most uncomfortable $300+ chair I have Ever Sat In
The construction of the chair is fantastic, very solid, seems durable. The assembly was easy and without problem. The lumbar support is way too big, protruding into my back and none of the height settings of the back rest put the lumbar support in the right spot. Within 20 minutes of sitting in this chair I had a back muscle cramp. The available adjustments were just not sufficient and the support is all wrong.Update: the seller was extremely responsive and worked very hard to make this deal right. The geometry is just wrong for my body shape, but I am satisfied with how the seller responded to my complaint.

Terrible experience
Ordered this as a Christmas present, beyond complicated to assemble, was unable to connect the arms cause parts were machined wrong, I go request a refund and they donât provide return shipping label and expect you to pay over a hundred dollars due to it being so heavy, spend the extra money with a known better quality product

Good Quality
This C300 chair is very good, I like it. The seat cushion is soft and supportive, and the dynamic lumbar supporter can fit well. This product is of very good quality. Meanwhile, they have great customer service. I contacted their customer service (service@sihoooffice.com), they addressed all my questions.

Customer service is good, Quality of product is poor
Bought this chair earlier this year and almost immediately had issues. Customer service responded immediately, offered half a refund and a new chair in return for deleting my first review. Deleted the review, received the chair and half refund, and had the same issues with the new chair.I do not feel it is fair to not share the negative reviews. For the money spent to buy this chair, people should know what they are getting into. I will be looking for a new chair to use for home office use, not continuing with Sihoo.

Sono un grafico e da più di 20 anni passo la maggior parte del tempo seduto di fronte al computer, quindi riservo molta attenzione all’ergonomia e al confort. Ho provato sedie di ogni tipo e credetemi la scelta è molto personale.Questa della SIHOO accontenta tutti, perché permette talmente tante regolazioni che sarà difficile trovare difetti o mancanze, anche se è bene fare qualche considerazione prima di acquistarla, ma andiamo per ordine…Arriva dentro un GROSSO e PESANTE scatolone. à bene che siate in due quando vi verrà consegnata perché sfiora i 30 chili.Una volta aperta la confezione, notiamo subito l’ORDINE e la CURA dell’imballo.Tutto ben protetto ed imbustato, con tanto di supporti antiurto e silica gel per l’umidità .Oltre al MANUALE (anche italiano) troviamo un paio di GUANTI monouso e due CHIAVI esagonali, una a “T” ed una a “L”, utili per assemblare l’intera poltrona in ben 8 passaggi.Le VITI e le RONDELLE sono disposte e divise su un cartoncino, numerate con codici e rispettiva collocazione (in inglese). Sono di buona fattura, quindi non si deformano durante i serraggi. Presentano un tocco di vernice blu, utile per fare presa sulla filettatura. Sono incluse viti e rondelle di riserva.Unica nota storta, le ILLUSTRAZIONI del manuale, sono veramente piccole e in alcuni passaggi ho utilizzato una lente di ingrandimento (non scherzo), ma con un po di intuizione arriverete a conclusione in circa mezz’ora e poco più, tutto dipende dal vostro grado di manualità e precisione.à realizzata per lo più in PLASTICA di ottima fattura, spessa e rinforzata. Seduta, schienale e poggiatesta sono rivestiti con un tessuto sintetico ed elastico, formato da una rete intrecciata che favorisce la traspirazione, ottima in estate. Si PULISCE tranquillamente con un panno umido. Supporta un PESO massimo di 150 kg.La poltrona consente molte REGOLAZIONI, nel mio video ne mostro alcune, tra cui altezza della seduta, posizione dei braccioli, profondità ed altezza del poggiatesta. Anche la bombatura lombare si muove adattandosi ad ogni tipo di schiena.Se non avete mai provato sedute ERGONOMICHE, vi farà strano sentire la bombatura nella zona lombare. Inizialmente sembrerà che la parte alta dello schienale sia troppo arretrata, ma è una caratteristica delle sedie ergonomiche. Vanta una seduta molto ampia, ottima per qualsiasi tipo di corporatura.Degni di nota sono i BRACCIOLI 3D, che permettono tante regolazioni, peccato che non possano essere fissati, perché tendono a muoversi con facilità , semplicemente sfiorandoli.Preferivo che si ribaltassero all’indietro, perché alcune scrivanie hanno un ripiano sottostante che impedisce alla poltrona di essere infilata sotto la scrivania.Considerate che con la regolazione più bassa, i braccioli distano 65 cm da terra.Volendo si possono smontare, ma solo la parte alta, perché la parte bassa funge da blocco per l’intera struttura.Sono marchiati con L e R, così da distinguere destra e sinistra.Ottime le 5 ROTELLE, scorrono bene e non si puntano, tra le migliori che abbia provato. Si fissano con un po di fatica ai 5 BRACCI in metallo, solidi e resistenti.Il PISTONE che decreta l’altezza è ben fatto, si regola con una LEVA di metallo con una MANOPOLA in plastica, non trasmette molta solidità , nonostante funzioni egregiamente.Con la stessa leva è possibile bloccare sia l’altezza del pistone che l’INCLINAZIONE dello schienale.Tali funzioni sono indicate nella manopola, purtroppo sono poco leggibili e poco intuibili.In CONCLUSIONE, non posso che ritenermi soddisfatto. La sto utilizzando da giorni nel mio studio e funziona egregiamente. Se nel corso del tempo dovessi riscontrare problemi o difetti, sarà mia premura aggiornare la recensione.Non costa poco, ma sarà tutto di guadagnato, dal confort alla scomparsa dei classici dolori dovuti ad una seduta errata. 5 stelle meritatissime!

Liebe Leser,wir dürfen den “SIHOO Ergonomischer Home Office Stuhl, Ergonomischer Computer Bürostuhl, Hohe Rückenlehne Mesh Schreibtischstuhl mit Verstellbarer 3D Armlehne Chefsessel Drehstuhl (WeiÃ)” testen und möchten diesen wie folgt bewerten:Nachdem unser alter Schreibtischstuhl den Geist aufgegeben hatte, freuten wir uns über diesen Test und bestellten diesen Schreibtischstuhl in der Farbe weiÃ. Nachdem mein Mann und ich auch immer mehr im Home-Office arbeiten, kam uns dieser Stuhl gerade recht.Als der Schreibtischstuhl bei uns kompakt verpackt in einem etwas gröÃeren Karton ankam, überraschte zunächst das doch sehr hohe Gewicht. Ich als Frau fand ihn schon relativ schwer.Der Aufbau hingegen funktionierte dank der beiliegenden Aufbauanleitung relativ schnell. Alleine benötigt man etwa 15 Minuten für den Aufbau des Stuhls.Als der Stuhl dann so da stand, war das ergonomische Design, sprich diese Lehne für den unteren Rücken erstmal etwas gewöhnungsbedürftig. Sowohl optisch, als auch wenn man dann letztendlich darauf sitzt war das Ganze doch erstmal ziemlich ungewohnt.Es gibt hier auch keine Möglichkeit diese Lehne zu entfernen. Man könnte sie in der Höhe etwas anpassen, mehr aber auch nicht.Zu den weiteren Funktionen des Stuhls: Die Armlehnen lassen sich ebenfalls anpassen. Sie können nach links oder rechts gedreht werden also nach auÃen oder nach innen. Die Kopflehne kann noch etwas weiter nach unten oder oben geneigt werden. Diese Lehne für den Lendenbereich kann eben auch noch ein wenig nach oben oder unten angepasst werden.Weiterhin kann der gesamte Stuhl mit Hilfe des Hebels unterhalb des Stuhls nach oben oder unten verstellt werden.Was wir ganz angenehm an diesem Stuhl finden ist, dass er komplett aus atmungsaktiven Meshgewebe besteht. Das Gewebe gibt zudem sehr gut nach und passt sich so sehr gut an den Körper an. Das macht ihn wiederum sehr bequem.Womit ich persönlich eben leider gar nicht klar komme, ist diese Lehne für den Lendenbereich. Ich denke auch, dass der Stuhl eher etwas für gröÃere Personen und nicht für Personen wie mich mit einer KörpergröÃe von 160 cm geeignet ist.Mein Mann hingegen ist 190 cm groà und findet den Stuhl – einschlieÃlich Lehne im Lendenbereich – sehr bequem.Sonst ist der Stuhl einwandfrei verarbeitet. Ich konnte keinerlei Mängel feststellen. Er lässt sich leichtgängig hoch- oder runterfahren und auch die Rollen gleiten leichtgängig über den Boden.Wenn man sich gegen den Stuhl lehnt, kann man ihn auch ein wenig nach hinten neigen (die komplette Lehne). So kann man bei einer Pause zwischendurch auch mal kurz den Rücken entlasten.Sonst verhilft der Stuhl tatsächlich auch ganz gut zum gerade sitzen. Dies habe ich bei anderen Stühlen so tatsächlich nicht.Die Optik des Schreibtischstuhls konnte uns ebenfalls sehr überzeugen. Er sieht schlicht und schick aus und passt meiner Meinung nach zu jedem Einrichtungsstil.Unser Fazit: Abgesehen von der Lehne im Lendenbereich finde ich den Stuhl sehr bequem und optisch natürlich überragend. Allerdings komme ich nur schwer mit dieser Lehne klar. Das Meshgewebe ist sehr atmungsaktiv was ein übermäÃiges Schwitzen gut verhindert. Er ist einwandfrei verarbeitet und lässt sich leichtgängig verstellen. Insgesamt vergeben wir deshalb 4 Sterne und empfehlen ihn dennoch weiter.Ich hoffe ich konnte Ihnen mit meiner Rezension weiterhelfen.Sollte sich etwas an meiner Meinung ändern, werde ich diese Rezension anpassen. (Stand 06/2023)

This mesh executive-style computer chair has a premium look and feel with great ergonomics and lumbar support. The chair has a full metal chrome plated wheelbase with smooth castors and gas lift. The frame/shell of the chair is made of a hard plastic material which feels durable but is a little bit flexible. The arm rests are firm but have a soft PU leather covering so they feel comfortable and supportive. The are 4D adjustable but there is no lock to set them into place, but this isnât a major issue.Construction of the chair wasnât the easiest experience, but following the instructions carefully we had no issue with building the chair, it just took a bit longer than expected. It comes pretty much unassembled with an array of different sized screws and washers that may seem a little overwhelming. Thankfully, everything is pretty well labelled and whilst the instructions are not the clearest or as well written as they could be, the diagrams shows the screws and washer placements and we were able to figure out everything without too much hassle. It comes with a handy Allen key screw tool and a pair of gloves which makes the assembly a bit more comfortable.Sitting on the chair it feels very comfortable and supportive. As itâs mesh, it is fully breathable and there is barely any heat buildup like you would get with a leather or fabric chair – this will be ideal for working from home in the summer. The back support mesh really helps ensure your back is supported and it flexes to fit your back in the right position. Initially I couldnât figure out how to lock the arm rest hight adjustment, I would raise them all they way up and they would just fall back down. You actually have to move them up slowly and listen for an audible click which locks them into place, raising them all the way up unlocks them and they will go to the lowest level.Overall, this is an excellent mesh chair that is comfortable, ergonomic and has essential lumbar support for long hours of seating. Thank you for reading my review, if you found it helpful let me know below!

This office chair from SIHOO arrived boxed with a promise of fairly quick assembly, though it took me a couple of hours in the end. I was pleased that each set of screws came with a spare, even though I didn’t need them. The instructions weren’t great, with the size of the diagrams unhelpfully small – at one point I had to take a photo of them and zoom into it. A couple of the wheels also took a bit of effort to insert but overall assembly wasn’t too bad.Assembled, the chair has a very smart modern look to it and is reasonably adjustable in that the back has a few lock positions so the lumbar cushion can be raised or lowered as required, for me it was the second setting up that hit the spot. The armrests can (and very easily do) rotate between six positions and can also be raised. The headrest is also adjustable. While I have no trouble reclining and locking it, I found the chair very tricky to get to lift but I need it left at the highest position anyway so now that I have done it I probably won’t be fiddling with that setting again.The chair is more than heavy enough to be very stable. It’s certainly comfortable to sit on, with the mesh feeling almost bouncy. The mesh parts let a lot of light through and the grey/white look suits my home office decor beautifully. The seat does seen quite large – it’s fine for me but I’m a big guy.Without a doubt this chair is far better than the chair I was using before, it allows me to sit at the height I need for my workstation and I am able to adjust it so I can sit very comfortably. The chair provides good support for my back so with all things considered I am very happy with it.

Ultimamente (e, a questo punto per qualche anno), io e mio marito lavoriamo spesso in “telelavoro”, e, obtorto collo, siamo stati costretti ad attrezzare le nostre rispettive postazioni di “gioco” in postazioni lavorative.Ciò ha comportato, nel corso dei mesi precedenti, la necessità di ritrovare quell’ergonomia che prima non era particolarmente utile, ma diviene indispensabile se si devono passare molte are attaccati alla sedia lavorando da remoto, e sono stata felice di ordinare questa sedia grazie al programma Amazon Vine.Arriva in una generosa (e pesantissima) scatola di cartone perfettamente imballata, in ogni sua parte, e con i vari componenti contenuti allâinterno di scatoline. Il manuale è anche in lingua italiana e lâassemblaggio è relativamente semplice. Non serve dotarsi di alcun attrezzo in quanto è presente solo una chiave a brugola, che serve per tutte le viti in dotazione.Lâimpressione allâapertura del pacco è stata ottima, il piede è davvero generoso e va assemblato su una struttura a stella, il tutto è incastrato e protetto in un gioco di incastri, nessun danno da trasporto, la base sembra abbastanza robusta una volta montata e con viti serrate.Il manuale è piuttosto scarno, ma, tutto sommato, abbastanza semplice da seguire, si monta in meno di una mezzoretta.Le ruote sono in plastica, oggettivamente non mi sono sembrate di qualità premium, si assemblano al piede, si mette il pistone, e si passa alla seduta. I filetti sono perfetti, facile assemblarli.La seduta è ampia, in rete, decisamente molto comoda (fin troppo morbida): fresco in estate ma, in inverno potrebbe infastidire. Di converso la pulizia sarà certamente agevole e non mi preoccuperò se mio figlio dovesse rovesciare qualcosa.Il pistone a gas è molto preciso, lâinclinazione non è estrema, ma è più che sufficiente anche per assumere posizioni di relax, è sicuramente più stabile di unâaltra sedia che avevo avuto la possibilità di ordinare dello stesso produttore.I braccioli possono scorrere avanti, indietro e lateralmente, molto comodi, è comunque possibile smontarli agevolmente, senza alcun impatto estetico significativo (il che, per un/una chitarrista, è sempre un plus gradito), certo che se il produttore avesse etichettato quello destro e quello sinistro nel pacco, il montaggio sarebbe stato più agevole.Il lombare è di tipo adattivo, e segue, inclinandosi, la schiena senza premere eccessivamente e senza dare in alcun modo fastidio. Lo schienale, di tipo traforato è molto fresco, e mi consentirà di passare ore al pc senza appiccicarmi alla sedia anche in estate, ma regolarlo in altezza è davvero complicato.Finalmente il poggiatesta è regolabile, non è troppo arretrato e ci si arriva, decisamente da promuovere il sistema di aggancio, che sembra abbastanza solido, ma è complicato regolarlo in altezza.I braccioli non possono essere allargati a meno di non svitarli da sotto, un sistema di scorrimento laterale sarebbe stato (visto il prezzo), molto più comodo ed utile, altro difetto enorme dei braccioli è che risultano essere eccessivamente laschi: al minimo movimento si spostano di lato e lo trovo piuttosto fastidioso: avrei preferito un sistema di fissaggio del bracciolo con sblocco a leva.In ogni caso è comunque un buon prodotto, dal design moderno, piacevole alla vista e funzionale, e abbastanza comoda.
