**Q: Can the back be locked in position at different angles?**
A: Just to confirm, the chair CAN actually be locked in reclined position. Recline back to desired level and then push the lever in to fix the position

**Q: You have stated to provide "zero profit product accessories within three years of warranty period", what does this mean?**
A: If the product you purchased is under warranty and there is a problem with the parts of the chair, we will provide you with free new parts to replace.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 4 Years later *edit* and 2 Months
*by  on Reviewed in the United Kingdom 20 November 2023*

I thought I should give an update, to my original review.After dismantling the chair, I thought I'd give tracking down a replacement part a try, after a bit of browsing I decided to contact SIHOO's customer services. The chair is well out of warranty but thought I might be able to buy a replacement.The reason I've bumped this back to a 5 star review is they sent out the part for free. My favourite price.The parts not an exact replacement but it turns it back into a functioning and comfortable chair.One issue to watch out for, the cylinder piston will be very well attached, I needed to buy one of these to get it to extract:https://www.amazon.co.uk/dp/B0C7VY2MX1?ref=ppx_yo2ov_dt_b_product_details&th=1(Previously)I've been using this as an in-home office and gaming chair for the last 4 years. Up to the last few weeks, it served my average size (6' tall, 14 stone) self well. It has seen some serious posterior hours in that time as like many I've been working from home and continue to do so. (8 hour working day and an evening of gaming most nights).When it arrived it was easy to assemble, a bit of hex key / spanner work during assembly but nothing tricky.The chair is comfortable, I have pulled 16 hour days in the thing with no issue (of course moving around occasionally, coffee doesn't make itself).Support wise it's adjustability is fine, good back and neck support. The neck could be a little stiffer maybe but not a huge deal.So, why the average review.The picture is the clue here. After 4 years of service the metal connecting plate of the backrest has started to bend and sheer. The washer's have squashed out of existence as well, maybe I could have caught the pending break if I'd spotted this earlier.If you're not going to sit in this chair night and day I think it's still a good chair. And if they were to extend the connecting portion of the frame it would probably prevent this from happening. It just has too much pivoting potential over those 3 screws.

### ⭐⭐⭐⭐⭐ This chair healed my back!
*by  on Reviewed in the United Kingdom 26 August 2021*

I’m not bothered in general with reviews, but need to write about this one! Soooo, I decorate cookies, work long hours and sit in a chair many hours per day... After 3 years of using a very humble office chair, with no back support, I ended up paying therapists, chiropractors, you name it- KCR... I thought my problem was my lower back, I couldn’t even walk to do my grocery shopping cause I felt pain all the way... I used to lean on the trolley🙈😢So in general I could not walk for too long, in the park with my son, I couldn’t stand too long to wash dishes, etc... I started to get really worried- and not working was not an option, as I’m single- So I said I’ll change the chair and see... Did a good search, and got this one cause I liked the idea of having the lower back adjustable cushion.I’m 5’7 feet, so not too tall, and the cushion is set to the max inside, and at the maximum height, unfortunately for others (cause if they’re taller they won’t be able to set it higher) - but for me it works, so am extremely happy about that!Everytime I sit, I feel like that cushion is massaging my lower back, and keeps my spine straight, for many hours- or much straighter than my old chair....I must have it for about 2-3 weeks, I need to say that I can happily stand and wash dishes, walk with no pain, or way less than before... 🥳🥳🥳 I’m so glad I got it, before I damaged any further my back from sitting long hours in the wrong posture...I have ordered the grey colour, suits my living room so nice, it’s literally beautiful! It’s a very heavy and sturdy chair, seems super strong and durable... Was a bit concerned when I saw the seat is made just of mesh, so will need to hope that will last...The airlift works like a charm, nice and easy... I assembled it myself, comes well packed with a nice key- really basic assembling (if I can do it, you can!🙈😂)Took me some adjustment to it, I mean time to get used to it, being so heavy and imposing, but now I’m ok, and most of all, really greatfull for getting rid of that silly back pain, till the point it was parallyzing and had to lie down!So for anybody working from home, and not only,(thus can be used in an office too) take care of your back posture as in time you’ll spend more money on therapies than on a good chair! Well worth the money!!!

### ⭐⭐⭐⭐ Very comfortable and very adjustable
*by  on Reviewed in the United Kingdom 22 June 2021*

It would be a perfect chair and I would have given it 5 stars if it wasn't for just one thing: it was a bit too low for me, even at the max height setting. I am 170 cm tall and have a fairly short legs (29"), and my desk is 75 cm high. But I loved every other aspect of the chair so much, that I decided to improve the a/m drawback by a simple DIY trick: I inserted a 1" (25mm) plank of wood (a decking board) between the titling mechanism and the actual seat making the chair (the seat position) 25mm higher. I had to buy (on Amazon) longer bolts for that, but it wasn't a big problem. It is much better now, but I still wouldn't mind it being another 1 cm taller.Apart from that, it is a perfect chair. It has a several must have features:* adjustable lumbar support. If it is too hard for you (though it is padded) you can insert a piece of foam between the provided lumbar support pad and the mesh fabric of the back rest (as I did - it will be practically invisible). The adjustment range is quite sufficient (up/down, back/front).* The headrest is very adjustable and very well anatomically-shaped. It makes a big difference and I use it often.* The adjustable arm rests are very good - setting the height right (level with the desk) prevents many problems associated with a prolonged use of a mouse. They move up/down, front/back and at an angle. The angle position can easily be changed by accident (when pulling the chair), but it is equally easy to correct it when it happens. The plastic of the armrests is not cushioned, but it is soft enough to be comfortable (it is not hard).* The back rest can be adjusted easily to several pre-set positions, and it being wider at the top supports your shoulders very well.The chair has a "premium" and stylish look and is very well made. It doesn't look too big even in a small study.In other words - a perfect and reasonably priced chair, but next time please make it a bit taller...
