Choose Sihoo by fit and adjustment needs
Measure your current seat position and desk clearance before choosing a model. Use the manufacturer’s exact UK configuration: C300, C300 Pro and C300 Pro V2 are separate products.
| Situation | Decision route | Useful next step |
|---|---|---|
| Shorter legs or below 160 cm | Check the minimum seat height first; rule out a chair if you cannot obtain a supported foot position. | Check S300 fit if you are under 160 cm |
| Fixed seat depth is a poor match | Prioritise a documented seat-depth adjustment and compare its usable range. | C300 / C300 Pro adjustment comparison |
| Headrest does not reach comfortably | Compare the headrest position against your seated torso length. | M18 headrest guide for taller buyers |
| You need comparable source data | Check specification dates and conflicts before trusting a single number. | Compare published UK dimensions and return costs |
Questions before buying
Which model should I buy first?
Start by excluding dimensions that do not fit, then compare the remaining adjustment options and the final price.
Is more dynamic lumbar support always better?
No. Check where the support contacts your back and whether its position or pressure can be adjusted.
Can the chair treat back pain?
A product feature is not a treatment recommendation. Obtain clinical advice for persistent or worsening symptoms.
