Overview
Two steel clamps make up this kit, designed to lock onto an office chair's gas cylinder and stop it from sinking, sized for cylinders between 0.98 and 1.1 inches in diameter with a hex wrench included for installation.
Think of this as a repair part rather than new furniture: it clamps the existing gas cylinder at a fixed point instead of restoring smooth pneumatic adjustment. That tradeoff, a locked height instead of full range, is the whole value proposition against buying a replacement cylinder or a new chair.
- 2-pack heavy duty steel clamps
- Fits 0.98 to 1.1 inch cylinders
- Hex wrench included for install
- Stackable for custom height
Who it's for
This makes the most sense for anyone with a chair that slowly sinks during the day, provided the cylinder measures within the 0.98 to 1.1 inch range. Not useful for chairs with a cylinder outside that range or for anyone who wants to keep full height adjustability.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fixes chair sinking without replacing the gas cylinder
- Steel clamp holds a set height under load
- Hex wrench included, no extra tools needed
- Only fits cylinders between 0.98 and 1.1 inches
- Locks height rather than restoring full adjustability
Performance notes
The clamp works by physically gripping the cylinder shaft at the height you choose, so once installed the chair can no longer sink past that point, but it also can no longer be raised or lowered the way a working gas cylinder would. Getting a proper grip depends on the cylinder falling within the 0.98 to 1.1 inch range the clamp is sized for, and multiple clamps can be stacked when a single one doesn't land at the exact height wanted.

Questions about the Jayen computer gaming chairs
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Will this fix any sinking office chair?
Only if the gas cylinder diameter falls between 0.98 and 1.1 inches; outside that range the clamp won't grip properly, so measuring the cylinder first matters.
Do I need to replace the gas cylinder to use this?
No, that's the point of the kit; it clamps onto the existing cylinder to hold a fixed height instead of replacing the part that's failing.
Can I still adjust the chair's height after installing it?
Not freely, the clamp locks the cylinder at whatever height you set, though the listing notes you can stack multiple clamps to fine-tune that fixed position.
