Allows the chair it's installed on to handle weights of up to 150kg, while allowing the user to adjust the chair height within the 'tall' range of measurements = 480-570mm. This Gas Stem is compatible with all of our ergonomic chairs.

Steps to Replace a Height Adjustment Gas Strut:

1. Lay down some material (tarpaulin or newspaper) to protect the surface you’re working on.

2. Turn the chair on its side and tap the centre of the base with a rubber mallet away from the seat. The 5-star base should come loose.

3. Use a pipe wrench near the top of the gas strut and twist until it releases from the chair seat. Apply WD-40 if you’re having trouble.

4. Place the bottom of your new gas stem into your chair’s 5-star base.

5. Lift both into the chair’s seat and flip it over. Everything should be fitted correctly.

6. Test the new gas strut by sitting on the chair and adjusting the height.

Give your legs the support they deserve with our Ergonomic Folding Footstool. Designed for the modern professional and anyone seeking relief from lower-body strain, this stool combines breathable materials with a versatile design to transform your seating experience.

Key Features

Height Adjustable: Seamlessly adapt the stool to your specific leg length and chair height, ensuring your hips and knees remain at the optimal angle.

Breathable Mesh Surface: The contoured, high-tension mesh seat provides firm yet flexible support while promoting airflow to keep you cool during long sessions.

Compact & Foldable: When the workday is over, the tripod base folds down for easy storage, making it perfect for small home offices or shared workspaces.

Sturdy Tripod Base: Engineered for stability, the reinforced three-leg design ensures your feet stay planted without the stool shifting or tipping.

Ergonomic & Health Benefits

This isn't just a place to rest your feet; it's a tool for long-term physical wellness.

Knee & Joint Relief

By elevating the legs, this stool reduces the acute angle of the knee joint. For individuals with knee issues or recovery needs, this elevation helps alleviate joint compression and can assist in reducing swelling by improving circulation.

Improved Posture & Circulation

Elevating your feet encourages your lower back to press into your chair’s lumbar support. This reduces lower back strain and prevents the "slumping" that often leads to chronic neck and shoulder pain.
