“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.”— MikeyyGee124 on r/OfficeChairs
“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.”— Practical_Necessary1 on r/OfficeChairs
“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.”— kukushechkin on r/OfficeChairs
“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.”— @EchoLiam-c9w on YouTube
“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.”— Soft-Rip4412 on r/OfficeChairs
“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”— Waste-Day6425 on r/OfficeChairs
“the current one i have is Sihoo doro s100 and it gives me a lot of lumbar pain”— PoundDouble1950 on r/secretlab
“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”— GlowSSB on r/OfficeChairs
“I bought a doro s100, I sat in it for 2 hours and felt my posture get noticeably worse. luckily I could get a return on it as it was still within the 30 day money back window. The upper part of the backrest sticks out further than the lumbar support which results in your spine being forced into an arched position”— Striking-Ad-7887 on r/OfficeChairs
“Oops, I don't like the structure, I'm sorry!”— @Felicia_moyo on YouTube
“The S100 should be illegal.”— @GameslordXY on YouTube
“Looks so skeletal...”— @splashjules on YouTube
