Sihoo Doro S100

Based on 24 comments across 4 communities
TL;DR
Comfortable and well-built for the price with adjustable lumbar that helps some sit for long stretches. But the spring-mounted dual lumbar pads draw frequent criticism for digging in, causing back pain or worsening posture; runs small for taller users.

62% of 24 verified owners recommend the Sihoo Doro S100, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

I recently purchased a Sihoo S100 chair and after 2 days of use there was staples popping out of the side of the seat. This caused one side of the seat to essentially deflate.

great price and well built product...this is awesome

The chair material looks good quality for the price. Plastic are smooth and look sturdy, the mesh is solid and can hold my weight well (as well as my pregnant wife). All the pieces feel solid. And the assembly was very easy.

YouTube— neutral

The chair looks breathable, but the mesh is kinda plastic stuff and not fabric. I hope it won't cause back pain.

I recently bought a Doro S100 and it's very comfortable. Now, I wouldn't recommend it if you are above 6.

I have the SIhoo Doro S100 since a few months and its fin, at the beginning i liked it, currently i dont like it that much but have some back problems. For me the lumbar support could be a bit higher.

YouTube— neutral

Love how easy it is to assemble! And the design looks aesthetic but too expensive for me

r/OfficeChairs▼ don’t recommend

Well, I have the exactly same problem. To mitigate it I put a pair of folded pants behind these flopping flops so they no longer cave in, it makes it a bit better. But honestly, I should just get rid if this chair.

I just got the Sihoo Doro S100 and I've liked it so far. It's very reasonably priced and feels quality.

YouTube▲ recommend

Love it’s 5 adjustable options which makes it’s flexible to anyone, tall or short.

YouTube— neutral

I love the mesh back, but worry it might sag over time and lose the support

armrest isn't that convenient, as it doesn't lock in a position and can slide with a little push, which seems a bit disappointing.

Ilgai ieškojau ir pasiėmiau šitą. Labai rekomenduoju.

Having tested the S100, I sent it back after a week. The lumbar support is useless for me, and the two pads are a bad idea. As they're spring-mounted, when you put pressure on them with your back, they pivot and don't hold anything.

YouTube— neutral

Wish the headrest tilted a bit, fixed angle not suit my sitting posture.

YouTube— neutral

I just wish they would make the assembly process a bit easier.

Well I just bought it but my ass hurts within an half hour. I will test it through the weekend and see if it gets better

Great lumbar support and mesh design. I love it

I don't see any difference with other chairs to be honest

the current one i have is Sihoo doro s100 and it gives me a lot of lumbar pain

r/OfficeChairs▼ don’t recommend

I find this chair simply awful; it ruined my back. I'm not heavy or thick, and I feel like the lumbar “support” sucks my back in and forces me to stay upright, which tires me out enormously and makes me sit in a bad position. I used it for 6-7 months, and then switched back to my old chair

YouTube— neutral

Looks so comfortable but the price is too high

Reddit▲ recommend

I find the Sihoo Doro S100 perfect.
