Gaming Chair ED-OM5-XT Tall Back, Deep Seat Office Master OM5 Tall Chair

Professional modern appearance for my medical office while providing comfort,fatigue free posture and effortless positioning.

The lower back support is the best I've ever felt in a chair. It's perfect. Maintaining proper posture feels completely natural. Would recommend to anyone who sits at a desk for the majority of the day. It's an expensive chair, but absolutely worth it.

I spend a lot of time working from home and this is a great all around office chair. It's also very comfortable when playing games. The back and seat are connected in a way that as you move, the base moves with you. It's extremely comfortable. Highly recommended.

I believe this is the most comfortable chair that I have ever sat in. It takes out all the adjustment and does it for you. Easily worth the price and works great with my gaming set-up/also for productivity.

I was a little overwhelmed by the choices in fabrics when designing the chair myself, it would've been nice to see example photos of similar chairs (where available) to demonstrate each fabric or frame choice.

That aside, I got the chair, undamaged. Assembly was easy (just put the chair on the stand) and I was sitting in the chair within 5 minutes. I use this chair at a computer both for work, watching of streamed video (TV style usage), as well as gaming. The automatic reclining and highly adjustable arms make switching modes really comfortable and easy.

Obviously, this chair (especially with all its additional options) is quite expensive, but this feels like a chair I'll probably be using for 10 years, so I don't mind the expense. The only downside is that I have this chair in my home office, but I have to sit in a 'normal' chair while I'm at work. I guess until we have a Jetson's style ability to shrink things and take them with us, I'll just have to deal ;)

I'm not a chair expert by any means so I will just list what I liked and do not like.
Likes:
-Helps me sit up straight more
-is very easy to lounge back in
-arm rests are very comfortable and adjustable if you get the nice ones
-overall very supportive and does cause any weird tense spots in my back, neck, or shoulders

One note is that I was concerned that the lack of a cushioned back (on my customized version) would make the seat uncomfortable, but the plastic flex back has plenty of give and is actually very comfortable. And breathable too!

Things I don't like:
- lack of height adjustment for the back. I get that the chair is all about not needing adjustments, but I feel like my tail bone just barely makes it up to the flex back and a shorter person would have a bad time.
-A lot of the features you'd probably want (like the arm rests) are not stock and cost extra
-Pretty expensive
-I still haven't found much use for the "waterfall lip"

I purchased this chair after watching numerous videos on gaming chairs and decided to try it. What I love about it is that the seat slides forward as the back of the chair reclines, this makes it super comfortable to lean back a little. What I hate about it is that the act of leaning back is just a bit too easy and there's no way to adjust this. In other words, what would make this chair perfect, is if there was a way to increase the resistance on the leaning back action. Otherwise, it's very comfortable and solved the issue I had were my thighs & buttocks were going numb during long work (or gaming) sessions. It's an expensive chair but has the quality to go along with it.

I gave this chair to my boyfriend as a gift. He is a big gamer so sits in his computer chair for hours at a time. He LOVES the chair. He has raved about the back support and the comfort of the seat. Great purchase.

I been using the chair for about a week and I absolutely love it! The wheels glide across the floor with ease and I really like the seat itself. I went with the extra memory foam option and it seems to pay off well. Warranty for the chair seems fair and if I get 5-10 years out of it that would be excellent.

ErgoDirect customer support was excellent! I worked with Anthony M. and he helped me every step of the way and answered all my questions with great detail. He provided me fabric samples and feedback from the manufacturer to help me make the best choices for this chair. He went above and beyond as far as customer service goes.

This chair is extremely comfortable. The self adjusting back works really well, supporting your back and bottom as both the back and seat adjusts to your leaning. For me and my weight, 162, it doesn't activate too easily so far. It's got just the right amount of resistance. The cushion was a little too hard at first, but after sitting in it for a month now it has softened up to a very comfortable level. I purchased the memory foam extra. I think it was worth it. This chair has completely fixed the problems I had with an Aeron chair I returned, namely the no cushion seating. The lumbar support is just about perfect for my height, 5' 8". It's also extremely well built, sturdy, and easy to put together. The adjustable arms are also nice and they don't slide back and forth too easily. Just the right amount of cushion too. They don't hurt my elbows. My only negative is that sometimes it wobbles a tiny bit, seemingly at the hydraulic stem. Depending on my sitting position though, I hardly notice it. If your leaning back a lot I would consider getting the higher back, especially if you're taller, as I missed the extra support on my shoulders when leaning back for a while. Was nervous because of the no return policy, but it was super worth it. Awesome chair.

Easy to put together; exceedingly comfortable chair. Loved the options to customize just what my son wanted. Considering getting one for myself given the price point, comfort level and helpful sales force from start to finish!

This is a very comfortable chair, one of the only chairs I can sit in for longer than 30 minutes without pain. Be aware though that the charcoal color is NOT black, it's a grey.

Everything about the chair is pretty great, outstanding craftmanship, quality materials, easy assembly, it looks great with all the options available and most importantly very little adjustment needed for optimum comfort. Only gripe though is when you lean back your body moves forward with the seat, while a lot of that resistance to hold the backrest in position is held back by the friction of your pants and the material on the seat (standard material-that is very rough feeling by the way) which can be uncomfortable at times which is as easy as just standing up and readjusting yourself to alleviate the issue. All in all I would still recommend the chair one year later even with the one flaw that is just a byproduct of not having to ever manually adjust the chair.

I bought this chair to serve as my desk chair for my gaming PC. I basically went all black with red as the seat (I believe I did molten but dont quote me on it). The chair is smooth over the tile of my home, I never get hot in it like I do with leather chairs (especially anywhere direct skin to chair contact happens). The height adjustment works great, and the mechanism that allows you to lean the chair back just by using your weight is easy to get used to, and works amazingly. The back is quite wide, wide enough for my entire back (I am 5' 10" with a stocky frame), but not so wide the chair is huge. First chair I have owned of its kind but I would highly recommend it.

No back pain since getting it. Can't believe I've been normalizing back pain from work all of this time. If you're thinking about getting this pull the trigger its worth it. Your future self will thank you. Also, thank you to ErgoDirect for the awesome customer service making customization of the chair hella easy.

This is legitimately the best chair I've ever sat in. It completely supports me while at the same time being very comfortable and able to lean. With the ridiculously easy instillation, I could not recommend it higher.

The packaging was a bit extreme (the box was way to large for the contents inside the box. Assembly was very simple. No complaints yet.

Where to begin?

The ordering process was incredibly simple, straight-forward, and plenty of reference. The contact at Ergodirect was nice, updated me periodically for my order as there was some delay, but oh, the wait was worth it. This is without a doubt the best chair I have ever sat in. Posture is already beginning to improve in the first few hours of owning it, the building process was literally three pieces, and the box it came in was sturdy, heavy, and huge. REALLY huge. Carrying that up a flight of stairs was a challenge, but all of it was worth it. Compared to the Steelcase Leap v2, Ikea Markus, an old $80 Office-Max cloth chair, and the DXRacer D-Series; this is a league above them all. The price is justified, and it feels like it'll last many, many years to come and with an improvement to my back and coccyx health. A note on the Steelcase Leap - it is a very nice chair, but pressure wise in regards to the cushioning placed a lot of unneeded pressure on the coccyx bone, the OM5XT has no issues in that regard what-so-ever.

Highly recommended, and highly comfortable. Also the white leather and white backing is stunning to look at.

All future office and chair purchases will be going through Ergodirect. It was an absolute pleasure.

I was hesitant to buy due to it being non refundable but after reading reviews and watching video reviews helped me decide. Also my husband bought one before me. It really helps you sit up straight, and comfortably. I've had tailbone pain prior to the chair and the way it helps you sit up correctly and the design of the seat tapering just a bit in the back I'm no longer sitting on my tailbone the wrong way so it's helped the pain go away. No need for one of those C shaped cushions with this chair.
Also I'm 5'3" and so I didn't get the XL (not sure the exact name, but I did not get the larger size) and it's perfect for my height. My husband got the large chair and it's too big for my height- can't sit all the way back properly in that size. He is 6'1" and the large is perfect for him but he does like my smaller version of the chair, but felt since the seat was smaller that the underside of his legs were uncomfortable hanging over. So size choice is important for your height.
We got "Cats" color fabric (I believe- it's a dark grey) and it's nice, not "computer chair" looking at all. Definitely stain/water resistant as my husband spilled coffee on his accidentally. Comfortable and sturdy. We got adjustable arm rests and we like them, nice to have. I don't think I'll use the adjustable feature pivoting them but still, nice to have.
Very happy with the chair. I work from home and use the chair often after hours for my own projects so both of us use them a lot. The paper coming with it says standard 40 hour work week. Take lots of breaks no matter what. But comfortable for the long run if it's what you need.
I hope this review is helpful.

I purchased this chair on recommendation from PC Gamer magazine. I recently started working from home full time and I also play PC games, so I initially looked at so-called "gaming chairs" such as DXracer. Most reviews of those claimed lack of durability or sustained comfort throughout the day. Most reviews actually recommended getting an ergonomic office chair instead, and PC Gamer Magazine specifically recommended the Office Master OM5. While I had the budget to pick something like a Herman Miller, the simplicity and sheer customizability of the OM5 were what made me go with it.

It provides incredible back support (as I try to sit at a 135 degree angle) and is very comfortable. It is not more complicated than it has to be. I also customized it to match the color theme I already established with my PC and other peripherals (black primary and blue secondary).

This is much better than any $50 office chair you could get, blows "gaming" chairs out of the water, and gives Herman Miller a run for their money.

Do not recommend this chair if you're over 250lbs. The padding isn't strong enough and it feels like your sitting on the seat pan which will dig into your legs due to the curved shape. The back and seat slider for the recline feature are excellent and great for the back. If it weren't for the seat it would be a perfect chair

Get a lot of compliments regarding its look and how comfortable it is!

I don't write many reviews online for products. I usually will only do that if it's something that is ridiculously impressive or ridiculously bad. I'm happy to say that this chair is on the ridiculously impressive scale. I had been searching for a new chair for my home office/gaming computer setup for a LONG time. At first, I was looking at some pretty cheap chairs and then, as I read reviews, I kept finding a great amount of problems with those chairs. I decided to up my budget a bit and looked into some mid to higher-end chairs which is where the OM5 comes into play. This is the one chair that kept getting consistently good ratings everywhere I looked, and reading PC Gamers' review of the chair had me take a hard look at it.

Let me first say, there are A LOT of options on the website and I feel that they need to provide you an example what your chair may look like before purchasing it online. This isn't a cheap chair when you start getting some of the add-ons, and because of that I think that customer should see a sample of what they're getting before they receive it. Besides that, I will say I had a really great experience with this company. I live near their HQ and the owner of the company accommodated me coming by on a Saturday to quickly test out the chair and determine if I wanted to get it. The second I sat in it, I knew it was what I wanted. Luckily, in person they have actual cloth samples for the different options so that made a HUGE difference in my selection.

Onto the chair, though. The chair is seriously the best I've sat on. I was coming from a really really old and crappy leather chair but I've also used Herman Miller and Steelcase chairs at work. While those other high-end chairs are great, I'd have to say I prefer this chair in EVERY way. The self-adjusting back mechanism ACTUALLY works as advertised. I feel supported no matter how far I go back in the chair. It's kind of an odd feeling but just really cool at the same time. In terms of the options, I know I had a lot of questions that I think I can help answer in this review. First of all, I'm 5'11" and around 175lbs. The EX is GREAT for this height and above. I think my biggest question prior to purchasing was whether I should get the mid-back or the high back and after sitting in it I knew the high back was the only answer. I also got the memory foam upgrade & the locking armrests. I think the memory foam upgrade is fantastic and, maybe even required for the best comfort. The locking armrests are good but, honestly, you could probably get away with the regular ones, no upgrades.

In summary, BUY THIS CHAIR. You won't regret it.

I am 6'4 and was nervous about ordering an essentially non-returnable chair (sight unseen to boot), but the initial anxiety was entirely worth it. This chair is extremely comfortable and sturdy, even the plastic/nylon feels solid. Considering my height, I opted for the 6" cylinder. I could have possibly gotten away with the standard shaft (set nearer to it's upper limits), but this configuration suits me just fine.
If you are taller than 6'4" you may want to consider the "XT" model with the deeper seat, I feel like I'm right on the border.
*note: I did not opt for the memory foam and the seat is still quite comfortable.

I have been using my OM5-EX for a couple of months now, and I love it! This is a sturdy chair constructed from durable material- even the plastic/nylon feels built to last! I am 6'4", medium build, and went for the heavy duty 6" cylinder. I probably would have been fine with the standard 5" (adjusted to it's upper height, of course), but my current configuration works just fine. I feel that I am right at the height threshold for this chair; if you are 6'6+, you may be better off going for the XT model. Be aware of various measurements (seat depth, seat height), as that will ultimately help you determine what's best for you- I used a tape measure on myself, as well as chairs around my home.

Finally, I didn't opt for the memory foam seating, and I feel just fine. Your preferences may differ from my own.

Great chair, no significant complaints!

I purchased this chair for my home office. I often work 8+ hour days and I am also a PC gamer in my spare time. I upgraded from a cheap Staples chair because I was beginning to have back pain and this was well reviewed online. I must say, even with the $300+ in extras on top of the base price, I feel like I got a great bargain. My back pain is completely gone after 3 weeks of this chair! On top of that, I had no idea how comfortable a chair could be before I bought this thing. If you are on the fence, go for it. You will not be disappointed. It works just exactly as described: it automatically adjusts to your desired position and stays until you want it to move. Everything about it screams premium. This should be priority for anyone who spends serious time in front of a computer because it will greatly and immediately improve your quality of life.

This is a great chair. Love the upgraded fabric. Would highly recommend upgrading the fabric. Very comfortable and keeps my back straight and healthy.

My wife and I are so glad we did our research and, finally, decided on the OM5. She teaches online classes and needed a chair that would really work. The lean-back (wow!) feature allows both of us to adjust/change our positions which reduces fatigue and back twinges. The ability to easily adjust the front of the seat is unique and we use it more than we thought we would. My wife found the ordering process to be perfectly detailed and worth her time - I left her to it when I realized it wouldn't show me what I was 'building.' She selected the leather seat covering and they turned out very classy.

Putting the chairs together was evidently easy since my wife didn't wait for me to help her. Little details, like the 'handle' on the back to pull the chair out were pleasant surprises and has added value to these already impressive chairs. Although we're not gamers, we do spend a lot of our time working at our desks and these chairs are perfect for hours-at-a-time sessions.

Once you get used to the way the chair reacts to your weight it functions flawlessly. The waterfall lip is a feature I never knew I wanted but now I have to stop myself from constantly messing with it. I've put in more than a couple long days into it and I only appreciate it more the longer I'll I use the chair for.
The only real problem I have is the arms, I wish they were longer or somehow followed the chair when you leave back in it.

All in all 0 regrets, great buy.

Compared to chairs you'll find at most office supply stores, the OM5's padding feels thin, firm, and oddly sculpted. The odds are decent you'll find it inferior or even mildly uncomfortable for the first 15 minutes after you sit down.

However, after you've sat in them for several hours, those store-sold chairs that make such great, pillowy first impressions have worn out their welcome and left your back in knots. Conversely, the OM5's sculpted and rather firm seat pushes your butt into a position that encourages correct posture, and the hands-free reclining allows the chair to continue fully supporting your back even as you adjust or stretch, both are things you'll come to appreciate by the end of the day.

The seat may take some getting used to and feel mildly uncomfortable or strange at first, but give it a chance at prolonged use. My first work shift spent in the OM5 was the first time in years that I didn't leave work with back and shoulder pain.

In terms of drawbacks, there's the somewhat underwhelming first impression I already mentioned. The price for the OM5 is also certainly of note, especially since I consider the headrest and adjustable armrests as must-have upgrades. The chair also arrived with a decidedly unpleasant plastic or chemical odor that took approximately a week to fade. At 6'0" I'm also not sure whether the OM5-EX can really accommodate people several inches taller than I am, but perhaps I just have a proportionately longer torso and neck.

Overall, the OM5 is a great chair, and something I wish I'd purchased over a year ago when I first began looking into them.
