Grendene - ESD and antistatic swivel work chairs
Grendene manufactures ESD and antistatic swivel work chairs and stools in the Gref series for ESD protected areas and demanding industrial workplaces. Through permanent contact the seated person stays continuously grounded, so electrostatic charges are safely dissipated and sensitive electronic components remain protected.
From a compact ESD stool to a fully equipped swivel chair with adjustable backrest, armrests, footrest ring and footrest, the series covers a wide range of seat heights and workplaces. Depending on the floor and application, models are available with castors, self-braking castors or glides.

Choosing the right Grendene work chair
Castors or glides?
The base depends on the workplace:
- Castors for tasks where the position changes often. Self-braking castors lock when you stand up and release under load.
- Glides for fixed workplaces and higher seat positions where the chair should stand securely.
Seat height and footrest
The series covers seat heights from roughly 420 to 700 mm. Lower positions suit standard workbenches, while higher tables call for models with a footrest ring or footrest so the legs are relieved. An adjustable backrest and armrests support an ergonomic posture.
Using the ESD function correctly
The dissipative effect relies on permanent contact between the seated person and the floor. For it to work, an ESD-capable floor covering and suitable footwear are required. This keeps the workplace continuously grounded and protects sensitive assemblies.

Frequently asked questions about Grendene
What does Grendene make?
Grendene manufactures ESD and antistatic swivel work chairs and stools in the Gref series. These dissipative seats are designed for ESD protected areas and for electronics and industrial workplaces.
How does ESD dissipation work on Grendene chairs?
The chairs use permanent contact: a continuously conductive path connects the seated person through the base to the floor, so electrostatic charges are dissipated continuously. An ESD-capable floor and suitable footwear are required for this to work.
What is the difference between castors and glides?
Castors allow the chair to be moved easily and suit flexible workplaces; self-braking castors lock when you stand up. Glides give the chair a fixed, stable stance and are especially useful for higher seat positions and fixed workplaces.
What seat heights does the Gref series offer?
The series covers seat heights from roughly 420 to 700 mm. Lower ranges suit standard workbenches, while higher models with a footrest ring or footrest are intended for raised standing and assembly workplaces.
Which workplaces are Grendene chairs suitable for?
They suit ESD protected areas as well as assembly, inspection, laboratory and production workplaces in electronics and industry, where sensitive components must be protected from electrostatic discharge.
