SIHOO Doro C300 Review

The SIHOO Doro C300 surprised me in a good way. It feels far better than most chairs I’ve used under $300. I sit long hours editing videos and writing, and this chair keeps my back calm. From setup to daily use, it feels designed for real people, not showrooms. If you want comfort without paying luxury prices, this chair earns a serious look.
