AI Summary
- A visible screw or product photograph does not prove the chair is intended to be used without its headrest.
- Check the manual for the exact version for a manufacturer-approved removal and reassembly sequence.
- If it is not documented, ask Sihoo about safety and warranty before pulling or cutting anything. Source 4
Decision table
| Situation | Practical choice |
|---|---|
| Manual explicitly describes removal | Follow the manufacturer steps and retain every part. |
| No removal guidance for your version | Do not force the frame or leave an exposed sharp connector. |
What to do
First record whether the headrest touches the neck or the back of the head and in which recline position. Try the authorised height and angle controls. If removal is allowed, check that the remaining fitting cannot snag clothing or skin. We did not establish an approved, damage-free removal procedure for both S300 and C300 versions, so this is a verification path rather than a disassembly tutorial. Source 2 Source 3
Resolve headrest contact before considering removal
| Observation | First check | Next step |
|---|---|---|
| Head pushed forwards while typing | Authorised height/angle position | Retest the normal upright posture |
| Contact works upright but fails in recline | Backrest position and headrest setting | Treat the two postures separately |
| Headrest contacts shoulders | Torso fit and usable backrest position | Compare another fit rather than forcing removal |
| Removal is proposed | Exact manual and written manufacturer answer | Confirm permitted use and reassembly |
Use the S300 specification, C300 specification and installation library to identify the actual version. Similar photographs are not enough to infer that the fastener layout is identical.
Send support the model label and a photograph of the mounting point, explaining whether you want temporary removal or permanent use without the part. Ask which fasteners are involved and whether removal leaves a connector that can snag clothing. Keep any approved instructions and all original fittings. If no authorised configuration solves the contact problem, evaluate the seller's return route before making an irreversible alteration.
Frequently asked questions
If I can undo a screw, is removal harmless?
Not necessarily; it may secure other components.
Will removal affect the warranty?
Ask the manufacturer about the exact version and proposed change. Source 4
Can I use the chair indefinitely without it?
Confirm that the manufacturer permits that configuration.
What if no headrest setting works?
Check the applicable return terms rather than modifying the chair.
