Ergonomic Office Swivel Desk Chair Executive Adjustable Headrest High-Back Mesh Task Gaming Computer Home Chair with Lumbar Support-Black

The most comfortable office chair I have ever had!I have a bad back and am in the office 2-4 days a week for long days that I am stuck at my computer and phone catching up on field reports and conference calls.In the 10+ years I have been at this company they have never had it in the "budget " to replace the 10-15 year old $100 budget chairs that are shot!My back could no longer take the sinking chairs and I bit the bullet and went out and bought this on my own and could now kick myself for not having done so years ago.Before joining this multinational company I worked for an company that truly cared about the health and well being of its staff and gave us all Aeon desk chairs - This $250 Rosmarus is as if not more comfortable as those $1200 Aeons.I hope it holds up and only wish I could afford another for use at my office at home.My only suggestion for improvement is that the Headrest is too small and set too far back to be of any use.

(((((UPDATE 5))))) I decided not to fight with the seller instead I ordered the parts that I needed that would support my 350 lb weight. I had to Spend an extra $70 to get it just right, This feels like steel and very sturdy, time will only tell. worst comes to worst I will commision a welder to fix the weak parts if it breaks. I live in a Naval city where there are thousands of welders building battleships here so it will not be hard to find a professional one.1)Mastery Mart Office Chair Base Replacement, 28 Inch Ultra Heavy Duty (1000 KG/ 2200 LB Rated) Metal Leg, Reinforced to Repair Swivel Gaming Chair with Universal Caster and Gas Cylinder Size (Black)Sold by: Mastery Mart $40.992)Kaleurrier Gas Lift Cylinder,Pneumatic Chair Replacement Parts- Chair or Stool Lifting Control Mechanism, 500 lbs Heavy Duty Steel Case,Chromcraft,in Universal Size,Height Extension(5.5" Stroke)by Kaleurrier (Wish they had a bit smaller but I am happy with it so far. )$15.903)Office Chair Wheels Casters (Set of 5) Heavy Duty Universal Fit Replacement Stem Caster with Soft Rubber Rollers Smoothly & Quietly, Safe on Carpet, Hardwood and All FloorsSold by: BeautyGL $19.90((((UPDATE 4)))) Apparently when One Wheel Breaks the stability of the Plastic completely crumbles, The material is trash plastic! apparently this mold comes from imperfect Plastic with not enough Oil resin and more garbage recycled into it with impurities. I do not recommend this seller. I brought this up to the seller and the seller does not want to own up to his mistake. Please steer clear of this seller and his products for they will only last 6 months maybe less. Right now I am going to go to a thrift store to see if I can find Desk chairs with Steel bases... Going to be a long day.(((UPDATE 3))) It is February 2020 and the part where the wheel is that came with the chair the plastic is not sturdy or thick enough to hold 300 to 500 LB I am so upset today there is no way to fix this! I can see the bad plastic mold was cheap and shoddy. So it isn't the rollerblade wheels as they said but the cheap plastic that the base of the pneumatic pump centers in where the wheels are is thin and made for 120 lb to 200 lb at most.((UPDATE 2)) Well It seeps that rollerblade wheels are too high if your 320 lbs if not the base part will break, I used the regular wheels and so far the Base is holding fine. I am using a Wooden floor to roll around. Oh so I got the replacement and once again the Back Panels to the chair seems to not fit in the rectangular slot, So I kept the old one and returned the new one that did not work. If your doing a replacement do not send the old one until you receive the new one that way you can match the parts and see which ones work for you.(Update 1) the plastic base had a flaw in it, it seems whoever molded it had molded it incorrectly. I have reordered the same chair, I hope I do not get the same problem from last time, not sure if the wheels I had caused it to break but I know that a chair base should never crack and break like this under 320 lbs if the chair is rated at 500lbs by seller.) I have to say the customer service is 5 star! Now the Pros: it is an upright position posture chair no doubt about it. Your inside legs at the knees will not touch the chair which is what I was looking for. If I wanted a recliner I buy a lazy boy. Now does it recline and support your head? You bet you It does! Once an comfy to catch a 20 min nap. Can you take the arms off? Yep yes you can! Does it hold 500 lbs.? Not sure about 500 but It is so far holding my 324 lbs of weight. If it does not in the future I will be upgrading and knocking stars off because this is one of the only reasons I would pay over $200 for a desk chair.The Cons: there are no major cons except for one flaw, some how the plastic for the posture back piece was not fitting into the groove, I have a dremel and I lightly shaved the plastic square hole to make sure it fits, it did! I assume that the factory messed up with the mold, I'm just glad I am handy with a dremel, and no sand paper wont work in such a tight square hole, dremel is the way to go, also I use the dremel to make complicated cosplay costumes. Lastly the instructions are vague! They are not step by step in details telling you what screws to use, just look at the picture and make sure you know what the front and back is according to the picture, they do come with extra screws, make sure the box is not damaged, the screws in the smaller box was damaged and was lucky they didnt get tossed around falling during shipping. Oh almost forgot, setting up the back of the chair only requires two screws when most chairs take 3, the base seems to take 3 but the back insert shows two, when I applied both close together in a long slot it was pretty sturdy. I used my power drill, did not want to hand tighten these screws.

I have the same chair at my work place, except this chair is a bit smaller. Great back support, but the head rest could be re-designed to have multiple positions to allow for more forward positions so that your head can actually rest comfortably.

I have ordered this chair, as well as a few others online in the past. I usually prefer to go to a store and test them out there, as there can a huge difference between how comfortable it looks, and how comfortable it is.The Rosmarus Ergonomic chair is, overall, a good chair. There are a few qualms with it, the first of which is the whole point of the chair (comfort and ergonomics) and the second is simply something any new company company will go through (materials and packaging) while figuring out their supply chain.Takeaways* The backrests are at first uncomfortable, but take some getting used to. In order to sit comfortably in the chair, you need to sit up straight with correct posture. Slumping down on the chair, or sitting at an angle is uncomfortable, so it good for posture when working. The Sertas I own were very soft and comfortable in any position, but due to that I would lean all the way back and slouched, which is very bad for the back.* The screws already being in the right places was a good touch, though the extra screws might throw people off.* When assembling the chair, the instructions were not very helpful. The pictures that were in it were small, and the directions for which way certain pieces (the back pads mainly) would be attached were not adequately given. I have talked with Rosmarus and they are working on providing better installation material for future orders.* Bits of the plastic underneath the chair stand started to come off just in the construction process. This is not entirely major, but could indicate problems down the line if the plastic is too brittle.* The chair does not feel as high quality as my previous chairs, both Serta's and that compete in this price bracket that are available at Office Depot usually for around $229 (they rotate sales prices every week or so, so you just wait until it hits the price you want, see Serta Jennings Chair) I was looking for alternatives that might be better, mainly since my Serta's squeak a lot and one is now peeling after 4 or 5 years.* The packaging material arrived completely tattered, albeit with a lot of tape.* Headrest is positioned too far back to use. I can't use it without leaning all the way back and looking at the ceiling.ConclusionThis is a work chair, and not a pleasure chair. This chair works best in your work or home office, where you sit for an extended period of time and need to be at attention.At home for comfort, the chair can be somewhat taxing, as it is not comfortable unless you sit on it properly. If you just want to relax at the computer with no care in the world, get a more casual, comfortable chair.If you want a chair that will keep your back straight, and head level, go for it.
