Best praise vs top criticism for Sihoo Doro C300
Best Praise
+8 pts“Sihoo C300 will work well for people under 5’7, but I’ll recommend you to check out Colamy Atlas as well, as they’re called "the best chair under $300” by BTOD.”

+3 pts“I found it difficult to find many genuine reviews of the Doro chairs. I did buy the C300 and I do regret it. The seat is much too small for anyone over 168cm. It also feels cheap. All the adjustments click into place. The gas lift is too low even at the highest height. With the slightest movement, the adjustable height of the back resets. The headrest is also pointless. Much too low for a tall person and as soon as you move it resets to a default position. I have had better quality Chinese chairs at half the price. ”
