Review: Love this Sihoo Chair! - Review of Sihoo M18 Office Chair purchased from desertcart UK for £139 in May 2026. This is an excellent chair, it went together easily, no problems with missing screws or badly drilled holes. The seat is firm but it's not uncomfortable and I understand it gets softer over time.-, there's adjustable incline which can be locked in different positions. I just leave it unlocked to rock back and forth. There's also adjustable lumbar support (up or down/ in or out). I'm 5ft 11inches tall and love this Sihoo Chair, it fits perfectly and is very comfortable. Reccommended.

## Questions & Answers

**Q: Can I just check the maximum seat height for this chair?  I'm 6'2" and most of these chairs don't seem to have a high enough seat.**
A: I'm 6'4" (34" inside leg) and with the seat fully up, it's the perfect height for me.

**Q: How about lumbar support? I suffer from low back pain because I work 10 hours a day. I need an ergonomic chair to relieve my pain.**
A: Regarding the adjustment of the lumbar support (as shown above), first of all, you can rotate the button left and right to adjust the position of the lumbar support up and down according to your lumbar needs, so that it fits your waist perfectly and relieves the fatigue of sitting for a long time.

**Q: What are the seat dimensions?**
A: It was difficult to measure the chair due to the style (it is very curved). The base ie. the seat is 47cm wide. The length ie. from the back of the base to the front is 56cm but this includes the downwards curve at the front of the chair. The back of the chair is approximately 83cm high and again this includes the curve. These measurements are all very approximate due to the curves. I am sure that someone else will give you different measurements! All I can add is that it is a beautiful and very comfortable chair.

**Q: I saw SIHOO's latest product, Doro C300, on social media. Will this chair be sold on Amazon?**
A: We really feel your trust and concern for SIHOO. The Doro C300 has been sold and can be directly purchased in our flagship store. This Office chair is very suitable for people who work for a long time, and for people of different heights and weights

### ⭐⭐⭐⭐⭐ Love this Sihoo Chair!
*by F***B on 9 May 2026*

Review of Sihoo M18 Office Chair purchased from Amazon UK for £139 in May 2026. This is an excellent chair, it went together easily, no problems with missing screws or badly drilled holes.

### ⭐⭐⭐⭐ Better than expected. Not bad for the price
*by J***3 on 26 August 2021*

It's massively better than Songmic Office Chair Ergonomic OBN52BKUK, which I bought for the spare room (although one might expect all these things are built in the same warehouse and designed by the same people). Like that, the Sihoo is limited and a tad flimsy around the arms, but overall, unlike the Songmic, it's overall a more comfortable sitting upright experience. The rollerblade-style wheels, which I'd never seen before on a chair, are of particular note: combined with the chair being fairly light, it's very easy to move around, it's like gliding, even on carpet. Ultimately, it is a cheap office chair, you go into it not expecting the best build quality, but to its credit it has decent lumbar support (far better than the Ikea Markus it replaced, and the Songmics), and just as crucially, a semblence of a headrest with a decent range of movement, which the Songmics lacks entirely. Frankly, I've used far, far worse chairs in professional offices back in the Before Times. Build is pretty easy, and the package includes a spare of everything, and an actually useful allen key with a big grip. I'm hanging on to that for future reference. My only real negative, even at this price point, is that while the back recline options are limited to two additional fixed positions as may usually be the case in these types of chair, neither of them feel right: even the 2nd position is a too far back for my taste, especially given the seat reclines with it, so it lifts your feet off the floor and you have to reduce the height, which is awkward as both are controlled by a single, dual-function lever. Still, for £136, and knowing the mesh will inevitably be torn to shreds by the cat in a few years, as happened to the Markus—hence why I can't risk even a second-hand Aeron—I don't think you'll be disappointed. Have low expectations, it will beat them easily.
