Sihoooffice - Reviews and experiences

Wasn't thinking much of a chair until mid‑afternoon; I’d first seen it on a Reddit thread and a colleague nudged me to give the C300 Pro a shot. The moment I tweaked the lumbar and armrests I knew it was worth it — the mesh and support really helped during a long slog. Not flawless — a tiny squeak and one trim feels flimsy — but support and quick service made me happy.

I sank into this chair after a 10-hour shift and was surprised — the lumbar support really moves with you, not like those stiff, fake backrests from cheaper brands I tried before. The mesh keeps things airy, and the headrest + 4D arms make fiddling with posture easy. Put together in under 20 minutes, no drama. Feels solid and not like it’ll fall apart in a year. Also, it's surprisingly comfy. Happy I upgraded, would recommend to anyone doing long hours at a desk.

I nearly skipped this chair because I worried about long term durability and whether support claims were just marketing. I use it everyday for work, usually eight hours with a lot of leaning on the arms, so that mattered. After about two years one armrest snapped. I expected a hassle. I emailed customer service and they answered fast, sent a replacement part without fuss and it actually has a revised shape that looks built to avoid the same break. So my scepticism eased. It's back in rotation and still doing the job I need, which is enough for me.

I opened one of the two Sihoo C300 Pro boxes last weekend — the build looked solid and parts like the armrests and lumbar support were actually pretty impressive. After I put it together (took longer than I thought) the mesh folds under me and it’s not comfy for my back, which is a bummer. I emailed support since their return policy said no-questions and free returns, but they sent a bunch of follow-up questions. One chair is still sealed, so I’m ready to send them back, but I worry they’ll make it slow. Still, there are some nice bits.

cushion could be a touch firmer. Overall, glad I bought it.

I bought this chair because it looked sturdy and felt comfy from the first sit — really supportive, good padding, I liked the tilt. After a few months the backrest started acting up (a bit loose, not locking properly), which was annoying since I use it daily for work. I contacted support; they were quick to respond and kept me updated, though the replacement took a while because of stock and shipping hiccups. What surprised me was they eventually offered a full replacement instead of making me wait forever for a part — that honestly made the difference. New chair arrived boxed well and is working fine now. I appreciate the clear communication and the patience of the team (they checked in more than once). Stuff happens, but handling it like this wins me over. Overall pretty happy with the chair and the customer care.

vague dates, broken promises, no proactive notice. One detail stood out: they didn’t tell me about the stock problem up front. That made planning impossible. I’m disappointed. Still hoping the chair shows up soon, because I do need it, but I won’t choose this seller next time.
