When you are sitting and working for long hours, if you are not careful you are bound to have medical issues. Until I had one, I continued with one of those traditional fancy chairs. After having cervical and lumbar issue, the diagnosis of which caused a lot, I started with my search for a good ergonomic chair to support my back/spine. I ordered even one for around 5k, but as soon as I opened the box, I raised a return because of poor quality. Post that I was clear that you get what you pay for...🎁 INSIDE BOX1x backrest1x seat1x locking mechanism2x handle1x castor and cover1x headrest1x gas lift2x allen key6x screws for handle, 3x for backrest, 4x for mechanism, 1x for headrest2x metal bush for handle2x plastic bushes for mechanism1x manual (printed colored booklet, not A4 papers some have received)Dimensions:Seat: Width 480 mm , Depth 480 mmBack (height from top of seat): 510 mmArm rest: length 240mm x with 70 mmLumbar adjustment: 35mmHeadrest/neckrest adjustment: 80 mm➕ PROS1. A chair with quality components and smooth mechanism2. Be it wheels, rotation of chair, up/down movement its quite smooth3. Gas lift mechanism is smooth, and provides ample adjustment of height (top of seat cushion from ground, with gas lift at bottom position ~450 mm, and with gas lift at top position ~570 mm)4. Removable head rest is a plus, since if you are not comfortable with it, you can remove.5. Backrest is made up of ~8-10 mm cushion (this is a non-mesh version where its just a mesh cloth). Even with this, you its quite breathable and comfortable for long sitting.6. Overall chair provides good support to your spine, and helps manage cervical and lumbar pain. I am using a 1" cushion as well to increase height of neck to align it perfectly with the head rest for proper neck support. I cant say much about smartgrid, as I have not disassembled any of back rest or seat.7. Adjustable armrest is a plus to give proper rest to arms and align position as per height of the table.8. Versatile tilting/reclining back, with adjustable tilt tension. Tension can be loosened to make it tilt with natural tilting movement of our back.➖ CONS1. Since I paid quite a lot for this chair, I expected quality across elements, but the castor cover was with unfinished edges, which I had to clear using a blade2. Better handrests could have been provided. These are a bit flimsy, and loose in the adjustable housing. Moreover, note that its hard plastic and no cushioning on the top.3. Lumbar support is not rigid and has a lot of flexibility to it (in description its being called as firm, but its far from it). Because of that, you dont get stable lumbar support.⚙️ USAGE SCENARIOSMy height is around 5' 4" and the headrest even at its lowest position, barely aligns with my neck. So anyone with lesser height will find trouble with it, as if your head actually rests on the center of headrest and not on the top, you will soon start having neck pain. Best position will be with its center of curvature aligned to neck, with head resting on top of it to keep spine straight.In such a case, you only have the option to use the chair without neck rest.🔨 PERFORMANCEAssembly may take anywhere between 15 mins to 60 mins depending on how proficient you are with toolsI used power screwdriver for faster assembly, as machine screws are provided which have fine threads, so lots of turns to screw/unscrew🏆 VERDICTI initially ordered a 5k chair, and the quality was pathetic. This is lives up to mark to provide good quality for the cost and provides sufficient support for long working hours. A few issues are there, but you get a good deal for the price you pay.

I recently purchased the rolling office chair "The Sleep Company SmartGRID Onyx High-Back Chair", and I couldn't be happier with my purchase. This chair has truly elevated my work experience to a whole new level.Firstly, the reclining feature is a game-changer. It allows me to find the perfect angle for my back and helps reduce strain during long hours of sitting. Whether I want to sit upright for focused tasks or lean back for a quick break, this chair offers the versatility I need.The hand rest height adjustment feature is another fantastic addition. It enables me to customize the chair to my liking, ensuring that my arms and shoulders are properly supported. This is crucial for maintaining good posture and preventing discomfort, especially during intense work sessions.The seat height adjustment feature is incredibly useful as well. It provides me with the flexibility to adjust the chair's height to match my desk perfectly. This ensures that my feet are planted firmly on the ground, promoting a healthier sitting position and reducing the risk of strain or fatigue.The chair's metal base is a mark of durability and stability. It not only enhances the chair's overall aesthetic but also adds a level of sturdiness that instills confidence while using it. The wheels glide smoothly, allowing for easy movement around the office without any annoying squeaks or hiccups.One of the standout features of this chair is its high backrest. It provides excellent support for my entire back, from the lumbar region all the way up to the shoulders. The ergonomic design helps me maintain proper spinal alignment, reducing the strain on my back and neck. The added height offers a sense of security and relaxation during those long work sessions.In terms of comfort, this chair truly excels. The padding is plush and supportive, allowing me to sit for extended periods without experiencing discomfort. The breathable fabric keeps me cool, even during the hottest days, preventing any build-up of sweat.Overall, this rolling office chair has exceeded my expectations. With its reclining feature, hand rest height adjustment, seat height adjustment, metal base, and high backrest, it offers the perfect blend of comfort and functionality. Whether you spend hours in front of a computer or have frequent meetings, this chair will undoubtedly enhance your workspace experience. I highly recommend it to anyone seeking a top-notch office chair that prioritizes both ergonomics and style.

The packaging was bad, no installation manual, instead of giving a spanner was given a L shaped rivet which took forever to tighten the backrest.The chair is not meant for tall people, maybe 4 feet tall people or kids can use it. I am 6 and only my buttocks can rest on this chair.Overall 1/5 for comfort, fit and packaging and ease of installation. I think there are better products in the nearby showrooms at lesser price.
