22 year old gamer approved.
Color: Black, Size: Mid Back
So far so good!! I bought this chair for my gamer son, he sat the springs out of his last one, so this one making it this long has me very pleased. It was easy to put together, and the quality is pretty notable, especially the wheels, super smooth rolling. It was definitely worth what we paid for it, and he finds it very comfortable, providing plenty of back support, and a stable seat for hours of gaming.

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)
