To adjust the stool, the button is pressed down by the activation lever found beneath the seat, opening a valve that allows the air to flow in and out. When someone sits on the stool, the air is forced out by the weight acting on the seat and the cylinder contracts, lowering the height.

And, designed to refill with air, it never needs topping up. Vice versa, when there is no weight on the stool and the button is pressed, the cylinders fill with air, expand and thus raise the seat. When not being pressed, the gas lift locks in place at whatever height it has been set to for increased stability.

The vast majority of adjustable models sit on single column metallic frames in mirrored chrome or brushed steel, making them great slimline minimalist pieces, as seen in the Oracle. Nevertheless you occasionally get an exceptional design like the Summit , which has a four-legged base for added stability as well as a striking look.

However, these methods only stop the seat from staying down once the cylinder has been broken. It will also not enable the user to adjust the height accordingly. Hence, it is not a permanent solution. A gas lift bar stool works differently than a hydraulic bar stool. The main mechanism is in the stem of the chair which connects the seat to the base. It is a pump full of pressurized nitrogen gas and oil that is sealed.

The oil lubricates the cylinder while the nitrogen gas stores energy in the spring. The two elements ensure smooth movements in the piston inside the cylinder when force is exerted on the lever underneath the seat. The piston forces air through a valve into the back of the system when the gas lift is pressed.

The air which was compressed then looks for its way out of the gas lift and that is when the stool changes its height.

In simple words, when the activation lever is pressed down, the piston slides back and forth, causing the top seat to move up and down. Additionally, the piston can slide more easily if the bar stool has a wide surface area, which will make the stools lift more smoothly.
