Review: Muy Cómoda - Súper cómoda! Muy recomendada
Review: Best office chair I've ever owned! - FIVE AND HALF YEAR UPDATE: Yes, I still have this chair and use it daily for many hours. Here's how it's held up. I haven't had any more parts replaced since the last update. I still say it's the best office chair of I've ever owned. It's certainly still in use longer than any office chair I've owned. The arms just will not stay tight. I find my self re-tightening them at least once a week, and even tight they still wobble a bit. That is probably the most annoying thing though. The leather in the bottom and back has held up great. No cracks or tears. Even on the arm rests has held up pretty well but starting to crack right on the edges. Honestly, if this chair had memory foam in the bottom I'd probably keep it another 5 years. I'd say overall I've more than gotten my moneys worth. I'll keep it around, but I'm in the mood for a new chair. I'll see what Serta has these days first. COMING UP ON TWO YEARS: I still say it's the best office chair I've owned so far, but the mechanical assembly again is going to need to be replaced under warranty. It's wobbly again, and pops very loudly every time you sit in it like it's about to break at any time. This will be the second mechanical replacement under warranty, we'll see if it goes as smooth as the first one. I also have a hard time still keeping the screws that hold the arms on tight. I tighten them at least every week if not more often. It's still comfortable however and so far is lasting longer than any office chair I've owned, and I've had many. UPDATE: I forgot to come back and update on the issue. Manufacturer replaced the mechanical assembly AND chair seat under warranty no questions asked! Bumping back to 5 stars. Gas pressure lift still working just fine. Since I have discovered they make wheels for office chairs that use the same wheels as inline skates. They are all over desertcart and I HIGHLY recommend ordering some, they are relatively cheap! I'll never own another office chair without putting those wheels on them. So much better than the plastic casters all office chairs come with and great if you have a hard floor! ONE YEAR UPDATE: 09/04/16: Original review below. I'm dropping a star pending finding out if I can get warranty honored. Just like every other office chair I've owned, the mechanical mechanism gets "loose" for lack of a better way to describe it, so it wobbles from side to side, and this chair has done that too. I posted originally hoping that the gas mechanism would hold up long term, and so far it has, but I've got to contact them about getting a warranty replacement for the mechanical assembly. Depending on how that goes, I may be back dropping more stars. Also, the chair cushion has flattened out quite a bit and not near as comfy as it was when I got it. ORIGINAL REVIEW: I'm a big guy, 6" 2' and about 290#. I have gone through a lot of chairs from the office box stores over the last 10 years. Even bought the big and tall versions they offered. They ALL failed. So much so I started buying the extended warranties offered just to get an exchange replacement in store. 90% of the time it's the hydraulic lift that fails. If it's not that, it's the mechanical part underneath getting wobbly. Padding never holds up. Based on the reviews here I bought this one, and yes its a lot more expensive, most expensive office chair I've ever bought, and it was totally worth it so far. Obviously I don't know about longevity yet, but it's the most comfortable chair I've ever had by several magnitudes. Assembling it, it was apparent the construction was heavier duty than any I've owned before, including the big and tall ones commonly found in the box stores. Make no mistake this is a heavy chair, you'll likely need help assembling it. It feels good and solid and comfy. My significant other is tall but skinny, only 120# and she even loves it so much she's thinking about getting one. We both work on our computers and spend a great deal of time sitting in these chairs, so you can't underestimate the value of a good, comfy, sturdy chair. There is one negative about it. I can't keep the arm bolts tight. I've found I'm having to retighten them nearly every day. I'm going to get some locktite on them and that should take care of it, they might consider including a little sample tube with the chair to put on those during assembly. But the chair is so nice otherwise I'm not even going to take away a star for that one.

## Questions & Answers

**Q: Does this chair recline?**
A: It tilts some like a rocker. It does not recliner like a recliner. The amount of tilt is small, regulated by a lever. The chair always stays L-shaped.

**Q: Are the arms of this chair made of metal or plastic?**
A: They look metal but are indeed plastic.

**Q: What is the measurement in inches between the rear of the custom (where the back touches the bottom) to the front of the cushion.**
A: If I understand your question correctly; it's 19 inches from the lumbar support, where your low back touches to the front of the bottom cushion where you sit. If I didn't understand your question, please ask again and I'll pull another measurement.

**Q: I'm interested in getting this, Is their chair hard or very soft when you sit on it?**
A: At first the seat cushion was great , but it quickly lost its shape and became very uncomfortable for me ...I had to find  a seat  cushion that seems to work pretty good for me now. I have this same problem with other chairs to be fair.

### ⭐⭐⭐ Great for occasional lounging and work. Not for extensive daily all-day use.
*by S***9 on 18 January 2020*

This review is after 3 days of use. Generally I'm satisfied with this chair. This chair is a solid 3.5 star chair. Assembly took strength and close attention to the instructions but was overall pretty easy and took exactly 1hr from delivery to assembly. The arms do wobble but not a huge deal. Seat cushion has a seam that causes some minor discomfort in the thighs but other pluses such as lumbar support and overall sturdiness make up for that. Leather tends to warm up after extended use. Not recommended for extensive daily use. But perfect for occasional work/lounging. If you are looking for a chair you'll be sitting in 8hr a day what are you doing on Amazon in the first place? Get off your butt and test out a few chairs at the store and make sure it's perfect in every way!
