Quality chair for the money.  A lot less then others.

The chair is comfortable and sits a little lower than my more expensive office chair, which is good, because you can slide under the desk a little bit more.  After I read a couple of reviews about assembly, I was expecting a nightmare, but surprisingly it was one of the simplest things I've  ever put together.  Even my wife, said "That was fast".  There were extra parts too - one long screw, one short screw and an extra cap.  The labels on the bottom of the chair and the hardware said "Front", which eliminating staring at a picture for half an hour.  Be sure to tighten each screw a little at a time and you will have no problem.  I put it together in 10 minutes or less and was pleasantly surprised.  I'll write a follow-up if needed.  This chair was $39 cheeper than the WM store.

Im a wimp with tiny little alligator arms so the chair assembly was sort of a challenge for me but if you have more muscles than I do, or if you have someone to help hold the parts together while you put the screws in, the assembly should be a breeze.  The screws are packaged individually for each step, which makes it simple, and an Allen wrench is included. (I taped the Allen wrench to the bottom of the chair for future use). The instructions are pictures with the parts labeled so they are fairly clear. In step 2 they could have made it more obvious that the backrest post is inserted all the way into the back and the screw goes in to the lowest hole. The post has two holes; only one hole is shown in the drawing.

The chair has a good range of adjustments as far as height of the seat and back. The arms are adjustable.  The back can be adjusted for amount of tension in the tilt.  The mesh back has as much give as a padded back. The seat is well padded and is covered with what looks like a heavy, good quality, textured material. It probably couldn't compare to a five hundred dollar chair but for a reasonably priced task chair I think it is a good choice.

If you have to contact customer service they are very helpful. It is good to know they stand behind their products.

We bought one of these for my 14 year old son and he was able to assemble it with very little help. I told him don't expect everything you buy 5hat needs assembly to be that easy. The chair is comfortable enough for me to sit in and Im 6 & >200 lbs.  it held up so well that we bought a second chair for another son. Ive been surprised at such high quality for so reasonable a price. Definitely recommend this chair.

I wasn't expecting this chair to be anything special. The price is relatively inexpensive for a computer chair, especially a mesh-backed chair - which usually results in a premium price. So I considered this to be a fairly low-priced chair and expected the quality to be lower as well.

I was pleasantly surprised. This thing is built rock solid. Every piece impressed me and I was confident after putting it together that it will last a long time.

I ended up giving it four stars. I started with five stars, then I deducted 1/2 star for the instructions, but put a 1/2 star back for the fact that they gave extra parts and for the sturdiness of the chair. I ended up deducting one star for the final flaw, which is lack of adjustability. You can adjust up and down with the typical pneumatic post in the center of the chair which raises and lowers the height of the seat, but there is no adjusting the back of the chair, or the arms of the chair.

Fortunately, it is fairly comfortable as is - for me at least. But I am sure that if I were to use it regularly, I would grow frustrated with not being able to adjust the chair's tilt.

In many ways, it is very hard to review a chair. There is a LOT of personal preference in whether you like a chair or not. But on the things that I can review, this chair is VERY WELL made in my opinion. It is well designed with spare parts (nuts and bolts) and can easily be put together in 20-30 minutes max. It seems fairly comfortable. It simply lacks a bit of adjustability for me to give it five stars.  Still, for a chair that is this low-priced, it is probably a five-star budget chair, and a four star chair overall. I hope that helps and makes some sense. Please feel free to write and ask questions if you have any, I will try to answer right away. :-)

For the money, this chair seems to be 100% up to snuff with the other racing chair brands that cost almost twice as much.  Assembly is self explanatory, so I'm not marking down for the lackluster instructions.  As for the Armrests, which a lot of reviewers are complaining about, I think they're great!  They mount solidly to the frame, so there isn't a wobble in the construction.  The wobble comes because the arms swivel into 3 different angle positions and they move freely between the positions by about 1/2inch each direction.  I find this to be a positive because I can move my wrists/arm with the mouse and the rest moves with me.  I don't know why anyone would not like this feature.  The armrests are made of a sturdy but soft rubber type material with some texturing that feels very nice.  Everything seems very durable and I've been sitting in the chair for about three hours now at almost the max height and I'm not experiencing the slow lowering that a few others mentioned.  As for the height, its another plus in my book.  My previous chair maxed out at a point that left my natural arm position about 6 inches from the top of my desk (custom built, way higher than average desk) but with this chair at max height I'm actually above the desk level, so I lowered it a bit.  So I'd safely say that this chair can fit almost any desk height without issue, much better than other office chairs!  The pillows are nice, if a bit firm, but they are easily removable or adjustable to your liking.  Overall I'm extremely impressed with the quality of this chair and recommend it to anyone who thinks the DX chairs are a bit too pricey.

UPDATE!!!! I've had this chare around a year now i think and it has totally broken.  It leans to the right after the metal that holds the hydraulics together literally snapped on one side. Also the steel frame on the right side broke where the seat curves up.  This may be my fault as I sit cross legged in the chair, but it's supposed to be STEEL!  Also my dog chewed up the armrests and the rests themselves seem to need constant tightening.  But here's the bad part:  I wanted to replace the chair after the bottom part broke causing the lean... and I can find NO INFORMATION ANYWHERE to contact Kinsal.  No phone number, no website, even amazon doesn't give you anything.  If you buy this you may well be stuck with it so BUYER BEWARE!  I'm only 170lb and this is rated at 350lb... but the frame and the metal box on the bottom have both snapped!  The weight limit is a lie.

My chair arrived before the time span advertised; "free" shipping, but not Prime.

Packaging was carefully done and delivery was professional. I was surprised at how relatively small the carton was given the size of the chair.

I had no significant problems assembling it which took about 20 minutes from opening the carton until completion.  No tools were required aside from the wrench that comes along with the hardware.  Truly a 1-2-3 assembly.

The chair is a near-twin to one purchased about a decade ago, which is still highly functional.  I expect this one will be around at least as long.

Time will tell regarding the comfort, stability and rest.  But for now, a quality item at a decent price.

Highly recommended for purchase.

Chair is well made...material should last a few summers and rust is not a major concern!!

Looks beautiful, is very comfortable to sit in.  The ease of assembly was just ok -- not difficult, but did require a little bit of thought and care.  I had to reinstall the seatback/arms after using the wrong mounting hole.  Also, the release button that allows it to recline was stuck when I received it.  I had to pull the cable manually and tap the button to "unstick" it.  I haven't had any trouble with the recline button since.  Besides that, the quality is very nice.  It's a solid chair that looks like it will hold up for a long time even with a lot of use.  I removed one star for the initally stuck button, and some slight scratching on the arm upon arrival.

This chair is good looking, comfortable, and easy to assemble.  It's a great investment for the money and I'm really happy with it.

Overall, this chair feels like the quality is above average for chairs of this type and especially in this price range.  The materials look good and have a nice feel (leather) and the plastic parts are well finished.  Everything felt solid and there were little touches that showed a better than average attention to detail.  Seams were all good and there were no blemishes of any kind (in itself fairly rare in this price range).  Once assembled, the chair looks nice and is comfortable, but this is not your lean back and relax type of "Executive" chair, this is more of a working, task chair.  Perfect for working at a desk.  You sit up straight and are well supported.  The adjustments work well and use a fairly typical mechanism.

I will be using this for working at a computer desk and it seems fine for that.  I have a larger "executive chair that's more of the "relax and read a book" type that I will retire and use for other purposes.  It has hard plastic arms and the padded arms of this new chair are much more comfortable.  The seat is very firm, but that is fine with me.  The back will not support your head (my other chair does), but that's OK for working at a desk where I will sit upright and active.

I was able to assemble this by myself with no help, but it would be a bit easier if you had someone to assist.  But I got it done in 1/2 hour and I work slowly.  The instructions were clear and I had no problems.  As others have noted, getting the back hooked up is the most difficult part, but even that is not too hard.  Would be easier with a second person, though.  But I was happy that I could get this done alone.  Some tips are follow the directions, move from bolt to bolt and back when tightening, don't just tighten one at a time.  Use the short L end of the hex wrench as the handle initially (insert the long piece into the bolt) and then switch to the long end (short piece into bolt) for final tightening.  Don't insert the bolt covers (the final step) put them and the wrench in a drawer and wait a week or too.  Then check and re-tighten the bolts one final time and put the covers in place.

Pros:  Good quality
  Good price
  Comfortable
  Easy to adjust
  Nice materials
  Fairly easy to assemble
  Was well packaged and had clear instructions

Cons:  None really at this price
  More of a task chair than an "executive" chair
  Back is not as high as most "executive" chairs (but high enough)

Bottom line:  An excellent value at this price

I'm giving this chair 5 stars for quality and value.  I will see how it holds up under use and if any issues develop I will return and update my rating (as I always do).

Update 2012-07-27:  After about 2 months, no issues.

Nice chair once you get it assembled. I was a bit worried by how banged up the box was when I received it, including metal parts of the chair poking through the cardboard but everything is in good shape. When you first unpack it, find the instructions (which are in a bag with the screws and hardware) and throw them away. Go to the Viva Office website and look at the instructions there. The ones that arrive with the chair are incredibly lacking.

I saw one complaint about the footrest not being far reaching enough for people over 5'2". Not sure where that info came from. I'm 5'11" and the footrest slides out plenty far enough for me. You have to both slide it out and flip it over to get the maximum reach.

The chair itself is very comfortable and seems sturdy and the lower back support feels great.

Very well made and comfortable, you will not be disappointed with this chair.  Would recommend though, as with all products in this category, you find a brick and mortar store and actually sit in one before ordering.  From the finish of the fabric seams to the activation of the height adjustment button - you will notice the quality.

Superb chair, high quality, arrive quickly and flaw free. Easy assembly in 30 minutes. Tremendous value. I decided to pay a bit more that other choices on amazon based on perceived quality in the reviews.

We got this chair for my wife's office. She really likes it. This isn't a crappy Ikea office chair. I've put together a few of those. This chair has lots of metal parts and is professional quality. Overall it's pretty heavy. The arms and frame are solid metal. The chair casters are plastic and metal, and the caster frame is metal. Assembly is pretty easy but the instructions are useless. There are some spacers that I'm still not sure if they're right. I'm 6'2" 260# and this chair is a bit small for me. My outer thighs rub the metal arms on the chair. Not really an issue since it's my wife's chair, just FYI.

After I finally finished putting together my desk (built from scratch) it was time to look at chairs. My problem is that I spend 7+ hours a day working on the computer, but 99% of it being pro bono, I don't have the budget for the chair that would do my back and my butt justice. So, I settled on this mid-price chair on the positive reviews here alone, and figured that I could always send it back if it wasn't a good fit.

*Edited at the bottom of the review - see why I downgraded to four stars!*

PUTTING IT TOGETHER
Building the chair was a relatively simple process. The wheels and base simply clicked into place, and once I figured out that I had put one arm on the wrong side, it was a relatively simple process to put the chair and arms together. The chair comes with all the hardware you will need, and also includes an Alan key for tightening bolts - for some people this will be important, as there's nothing worse than not having the right tool for your new toy!

CONSTRUCTION/QUALITY
I have only owned older or cheaper chairs, but I do have friends with high-end chairs, and I'm pleased to say that this one in particular is just about right for the price-point. The overall build seems just fine - it's not rickety by any means and if you tighten the bolts properly there shouldn't be any give. The wheels move well, although I'm on hardwood so I'm not sure how they fair on carpet. Despite the arms and base being made of plastic/nylon, they are a very strong grade and should hold up just fine (I will update the review with any change in this).

ERGONOMICS/COMFORT
I find this chair to be very comfortable overall. There is some (set) lumbar support, and I find it quite easy to sit up straight without having to lean to far back to type comfortably. The chair comes to a nice height at the back (I'm 5'9"), and you can lean it back and set it or allow free leaning with the use of the side lever. The chair has a decent range in terms of height, although if you're taller or have a tall desk, you might find that it doesn't go as high as you might want. The seat is reasonably comfortable - it's definitely not the best I have experienced but so far has helped alleviate any serious fatigue - a legitimate concern when you spend many hours a day at your desk. The arms are unpadded, but not uncomfortable. I rarely use the arms, unless I'm watching a video or taking some time to think, so I didn't really weigh them in to my rating.

OVERALL
For the price I paid, I am very pleased and at this price point I believe the chair merits the full five stars. I now have a comfortable, decently-made chair for less than a hundred dollars (at the time of this writing), and it has definitely improved my ability to work for longer stretches, allowing me to finish up a day's work more quickly! Overall, I can definitely recommend this chair as an excellent contender in this price range!

*EDIT*
Well, I decided to downgrade this review to four stars. After having the chair for several months, the seat padding has greatly decreased in effectiveness. Now granted, I use this chair for several hours every day so this may not apply to some people considering the chair, but nevertheless it is worth mentioning. It was only when we purchased a second chair for my wife that it became clear just how compressed the cushioning had become - you could actually feel the difference in height! I will be buying a chair cushion to alleviate this, so I still can recommend this chair, but perhaps with a little less enthusiasm.

The chair satisfies my most important needs so far.  I will re-evaluate this review in a few months.  But, the chair back comes up far enough for my head to lean on.  The cushions of the chair provide support without being hard as a rock.  They aren't cushy like a more expensive chair that I wanted from Haverty's, but I couldn't do the cost of that chair.  The complaints about the recliner being hard to open/close - I don't find that it's really that bad.  Certainly not any worse than one of my recliners that I already have in the house.  I have an ottoman, so don't plan to use the recliner much.  I am only 5'1 and if I sit all the way back, my feet don't touch the ground.  If I slouch I might be able to touch the ground - I am used to this on most couches or recliners.  I bought an ottoman to match for this reason.

The quality of the fabric is nice, and it looks very nice in person.  I don't know how well the chair, quality wise, would hold up under heavy use by my husband who is much larger than I am and also a bit rougher on things than me.  He won't be using the chair at all so if it doesn't hold up, it won't be from heavy use.

Overall, I am happy with the quality of this chair, and the things that I was looking for the most -- comfort, high chair back to lean my head on, smooth motion, and the look of the chair.
