## Description

Ergonomic chair with S-shaped backrest, adjustable headrest, and 3D armrests for long-lasting comfort and customizable support during extended work or gaming sessions.

Review: Fantastic - I was a bit unsure with a mesh bottom at first, as there’s absolutely no support or cushioning. But in all honestly, it’s fantastic - really comfortable, high quality and provides plenty of support. Really easy to assemble, and looks fantastic too. I got it on the prime day sale so got an absolute bargain too!
Review: 4 Years later *edit* and 2 Months - I thought I should give an update, to my original review. After dismantling the chair, I thought I'd give tracking down a replacement part a try, after a bit of browsing I decided to contact SIHOO's customer services. The chair is well out of warranty but thought I might be able to buy a replacement. The reason I've bumped this back to a 5 star review is they sent out the part for free. My favourite price. The parts not an exact replacement but it turns it back into a functioning and comfortable chair. One issue to watch out for, the cylinder piston will be very well attached, I needed to buy one of these to get it to extract: https://www.desertcart.co.uk/dp/B0C7VY2MX1?ref=ppx_yo2ov_dt_b_product_details&th=1 (Previously) I've been using this as an in-home office and gaming chair for the last 4 years. Up to the last few weeks, it served my average size (6' tall, 14 stone) self well. It has seen some serious posterior hours in that time as like many I've been working from home and continue to do so. (8 hour working day and an evening of gaming most nights). When it arrived it was easy to assemble, a bit of hex key / spanner work during assembly but nothing tricky. The chair is comfortable, I have pulled 16 hour days in the thing with no issue (of course moving around occasionally, coffee doesn't make itself). Support wise it's adjustability is fine, good back and neck support. The neck could be a little stiffer maybe but not a huge deal. So, why the average review. The picture is the clue here. After 4 years of service the metal connecting plate of the backrest has started to bend and sheer. The washer's have squashed out of existence as well, maybe I could have caught the pending break if I'd spotted this earlier. If you're not going to sit in this chair night and day I think it's still a good chair. And if they were to extend the connecting portion of the frame it would probably prevent this from happening. It just has too much pivoting potential over those 3 screws.

### ⭐⭐⭐⭐ A good, premium bit of kit. Thumbs up!
*by R***S on 23 July 2026*

Chuffed with this. Chair real straight forward to assemble and a lovely tool provided for the bolts, much better than the usual allen key you get. Made it a lot easier. Chair is sturdy , feels well made, feels expensive. Ideally would have liked a bit more adjustment on the lumbar support, but other than that, nothing to fault. No actual user operation instructions provided (other than assembly), which felt a little lacking, but simply review the video on the website for those instructions. 3 year guarantee seals the deal. Highly recommended.
