The back of the chair is not supportive
Color: Brown, Size: Mid Back
Really nice casters that truly roll quietly. The faux leather is stitched well and sturdy. The only problem i have is that the back is not adjustable and gives 0 back support. The whole back of the chair is hollow inside so your lumbar gets no help. The seat is comfy but super wide like a lot of other reviews mentioned

Stick with Name Brands
Color: Grey
Product arrived as described. I am 47, 5'9" and 195 lbs. I suffer from lower back pain. I am a graphic designer that spends hours in front of the computer. I purchased a less expensive chair, but it made my back feel like it was on fire and I was hobbling around the home like an elderly man. It wa sa gaming chair, with a cool look, but horribly uncomfortable—about $75 less than this chair.
I decided on Serta due to the brand recognition and quality of build. The chair arrived without blemish. It's very easy to assemble, taking me about 20 mins. I am very pleased with the look and quality of the leather. The seat cushion and back rest is quite comfortable. Firm, but soft, not too firm, but not too soft. I spend long hours at my desk and so far my back feels great. No burning, no hobbling. It's worth the extra $50-100 in cost. Happy customer.

The Most Comfortable Office Chair that I've Owned.
Color: Grey
This is by far the most comfortable office chair that I've ever owned or sat in. I've owned quite a few office chairs. Some big and comfy, some new ergonomic designs, some super expensive, others supplied by my employer, and even 2 other/prior Serta chairs. This, by far beats them all. I first purchased this chair for my wife in her office. She's of average size as well, but she always felt like she was being swallowed by some of the larger, more cushiony office chairs. She wanted to be comfortable, but didn't want to drown in the chair. I purchased this chair for her and she absolutely loves it. It's been a year now, and it's holding up well, looks great, and she has zero complaints. Which brings me to my personal purchase for myself. I'm average size. A little bulky, but not too big. I've been through so many chairs. They all feel great initially, but after a lot of use, I felt uncomfortable, or fatigued from sitting, and even sore. I have some lumbar back issues, and my tail bone occasionally gets sore if I sit too long, especially if I slouch over time. I was ready to buy a new chair, and it takes me forever to decide, however I do really like my wife's chair. So I purchased this chair for myself. I must say, that this chair is the best that I've used. It's not huge. You wouldn't be too comfortable trying to nap in it. But for sitting and working? It's amazing. Perfect lumbar support, super soft on the butt without swallowing you, and keeps you straight, and comfortable. I would definitely recommend this product.

Petite person's perspective
Color: Grey, Color: Grey
Full name on the box: Light Grey Bonded Leather/Mesh Air Executive Chair (Model: 43807)
This review is from a petite female’s perspective
I was browsing for couple months and this Serta chair stood out to me, mainly aesthetically. I don’t see many chairs in this color or style. It matched with the rest of my PC/desk setup.
Positives
-Seat is comfortable.
-Lumbar support is good. It helps me sit very straight.
-The casters were surprisingly easy to put in. I had to use some force with two of them though. They roll fine on carpet.
-Easy assembly
Neutral/Negatives
-Paint of armrests is easily scratched. I accidentally scratched it while installing the back.
-The black plastic caps used to hide the screws don’t fit well. The plastic inserts for hiding screws in arms don’t fit well either. It makes the chair appear cheap. (I will provide images)
-Craftsmanship isn’t the best. Not noticeable from a distance though.
-At lowest setting, my feet can’t touch the ground but being 4’11” it’s to be expected.
-Height of the back is too high for my liking. I prefer a few inches shorter so I can tilt my head back to rest my neck. My fault for not realizing I should look into "mid-back chairs".
-Head/top area is too firm. I prefer it to be squishy (e.g. Serta Smart Layers Verona or Siena).
As another reviewer mentioned, don’t forget to remove the foam or cardboard behind the lumbar and head/shoulder. That is supposedly the last step when assembly is all done.
**If you come across any issues/warranty, you contact TRUE INNOVATIONS, not Serta. (I will provide images)

***Serta should recall this chair!
Color: Grey
Serta quality and comfortable for office use only, casual home use isn't the same... the only reason I didn't give it 5 stars for ergonomics is that if you are not sitting upright in "office mode" and you want to slouch and relax, the seat makes you feel like you are always sliding forward in the chair? I assume that is because it's an "ergonomic" chair, but it is well built and worth the price in my opinion.
***Updated addition; after using the chair to work from home & casual use, it is still annoying to feel like it tilts forward unless you are sitting up perfectly straight! I have also noticed that if you get up or reposition yourself (due to the forward sliding) the seat height resets itself back up to the top!? So when you sit back down you have to lower the seat again... my last Serta chair never had these issues!! For the price point, this shouldn't be a chair I will be replacing after a few months - but not with another Serta!
****Second update = now 1 star! (Chair still looks new, I only work from home 1 day a week, and take great care of my things so there is no damage or even usage wear) After trying to make the best of this chair, it is even more annoying to use.. it now "groans" when any movement rocking back or forth... it still feels like it is forcing you to slide forward and feels like the chair wants your to fall out! Leaning back doesn't stay (no adjustment to keep from "leaning forward") so no matter what I do, I hate sitting in this chair more every day... and now I am very worried about buying another chair blind online!
***Serta should recall this chair!
*****Third update = Chair still looks and feels brand new, but now randomly will make weird creaking and groaning noises with every movement and as an added bonus it randomly just sinks to the lowest level without warning!!! Typing away and it just starts sinking until it hits bottom!
I don't know how an expensive chair could be so awful!!
