Well-packaged, quality materials, easy to assemble, very comfortable, great customer service
Color: Black Full Mesh, Style: Executive
When I received this package, I was surprised at how small/compact it was--hard to believe a high-back office chair could fit in that box! As I unpacked it, I was impressed by two things: first, how incredibly well it was packaged with an obvious intent to protect the components; second, how solid, heavy-duty, and high-quality those components were.
I got the box unpacked and read the instructions. They were simple and easy to understand, and included so many "here's a good tip" notes that it was obvious that a lot of thought and experience had gone into writing them. I found the chair simple to assemble and had it done in less than 15 minutes.
The chair was very adjustable. I was able to get the height to exactly what I wanted with no trouble at all. I was also able to adjust the height of the lumbar support, and to adjust how far it extended. There are a lot of adjustments you can make, the instructions lay that out quite thoroughly, too. As a result, the chair was very comfortable and helped me sit with a healthy posture.
I bought this chair because I had begun having an ache in my lower back, which I suspected was due to a chair I had been using for over 5 years. Within 3 days, the back pain was gone.
I was also very impressed with the customer service. Their manual mentions in multiple places things you can try if you have any issues, and always ends with "call us". Their team reached out to me after a few days to make sure I got the chair assembled with no issues and that it was comfortable. This was all part of the all-around quality of this purchase.
I'm very happy with this chair!

Comparable to Higher-End Chairs, Solid Build and Support Without the Premium Price
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
I’ve been using this chair for a bit now and it’s been a genuinely upgrade. The build quality stands out right away, it has real heft and doesn’t feel cheap or hollow. Everything fits together cleanly and once assembled it feels stable and planted. I’m over 6 ft and 200+ lbs and it handles that without any issue, no creaking or sense that it’s being pushed to its limits.
There’s enough space in the seat and back that you don’t feel boxed in. I added an extra ergonomic cushion and it still feels roomy, which isn’t always the case with chairs in this category. The adjustability helps a lot here, especially the lumbar support. Being able to move it up and down and also forward and back makes it easy to actually get it where you need it, instead of just accepting a fixed position. The armrests are also easy to dial in, especially if you’re switching between typing, reading, or leaning back a bit. The tilt range is useful, and the tilt tension is stronger than I expected. Even at my size it takes a bit of effort to lean back, which I see as a positive since it feels controlled and supportive rather than loose or overly easy to recline. The mesh is another strong point. It came in perfect condition, no snags, no loose threads, no rough edges anywhere. There weren’t any bits of untrimmed plastic on the frame either, which says a lot about the quality control. The mesh itself is taut with a bit of bounce, so it doesn’t sag but still has some give, which makes long sitting sessions more comfortable.
Assembly was straightforward and clearly thought through. The instructions are easy to follow, but what stood out were the built in redundancies that keep you from second guessing anything. There are multiple left and right indicators when installing the arms, a clear front facing marker for the gas lift, and the screws are labeled in the packaging so you’re not guessing which goes where. It’s one of the smoother assembly experiences I’ve had.
I also reached out to activate my warranty and had a very positive experience. I spoke with Alice who was very knowledgeable, quick, warm, and they went out of their way to help me with whatever I needed. When I inquired about the extra screw holes under the chair, she let me know that this was for a foot rest which was still in the production phase and unprompted offered to have one shipped to me when they were ready! There is an excellent team behind the product.
Overall: well built chair with good materials, thoughtful design choices, and good adjustability to make it work for different setups. It feels durable, comfortable over longer periods, and especially well suited if you need something that can handle a larger frame without sacrificing support.

Great product AND customer service!
Color: Black Full Mesh, Style: Executive
I'm having a hard time writing this review because I can't tell which one I like better: the product or the customer service!
I work on a computer all day, so a comfortable office chair is critical for me. This chair is great - it's adjustable in every way I need it to be, especially the armrests. The breathable mesh is both durable and supportive, and is more comfortable to sit in than the "overstuffed" chair it replaced.
Let me just say: no company provides better customer service than MOLENTS. Right after assembling my chair (which was very easy, btw), I registered for the 2 year warranty they offer. The NEXT DAY I received an email from Alice in their customer service department 1) to confirm my warranty, 2) to tell me about the free foam seat cover they were sending me, and 3) to make sure the chair was comfortable and easy to assemble. Very few companies take the effort to follow up with customers right after making a purchase like that.
I'm extremely happy with this purchase. This chair is worth MORE than it's weight in gold, and I strongly recommend to anyone thinking about buying an office chair to buy it from MOLENTS - you won't regret it.
Oh, and if Alice's supervisors are reading this: she absolutely deserves a promotion!

good chair for price
Color: Black Full Mesh, Style: Executive
I have had for about 2 months and seems to be holding up well, so far, and is comfortable for most part. Only complaint is the arms do not lower a lot, so cannot go under the desk.

High quality and incredible customer service
Color: Black Full Mesh, Style: Executive
This is an extremely well made chair at a very competitive price. The packaging, assembly instructions, as well as the way the hardware was packaged and labeled is probably the best I've seen. I'm particular about tools, and the included allen wrench was better than the normal "included tools" so much so that i actually used it rather than one of my own. The assembly was easy, and the chair itself looks and feels very high quality, and is very comfortable. Perhaps best of all was the level of customer service. I emailed on a weekend to activate the warranty and request the free cushion they offer. I got a personal response in less than a day and they offered upgraded wheels for free as well. This is a company worth doing business with.
