ESD Chairs

Why ESD Chairs Matter in an EPA

Electrostatic discharge occurs when static electricity builds up on the surface of any non-conductive object that rubs against another similar non-conductive object. Static charges can generate easily when sitting down or getting up from a chair. The contact between your clothes and the chair can cause this static generation to build on the chair and on your clothes.

While you stay in contact with the chair, your body voltage stays low. If you lean forward so your back moves away from the chair back, or if you get up out of the chair, then you take the electrostatic charge with you.
Your body voltage can rise very rapidly to a high voltage as the charge is separated from its counter charge on the chair. Even though you may not feel this static charge on your body, you should be aware that this charge can be passed to static sensitive electronic components nearby and can significantly damage them.

ESD chairs reduce this risk by dissipating static charge safely through a grounded path such as a grounded ESD floor. Ensuring the right seating is in place helps protect equipment, maintain compliance and support operator comfort.

How an ESD Chair Works

An ESD chair balances the electrical potential between the operator and the environment. Conductive materials and grounded castors allow static to dissipate safely when used in conjunction with a grounded ESD floor. For the chair to work correctly:

• The resistance to ground from any seat contact point must be less than 1×10^(10) Ω.
• At least two castors or glides must provide a reliable path to ground.
• The user must stay in contact with an ESD floor or mat, or use appropriate anti static wrist straps and footwear.

This ensures the whole ESD control system remains effective.

Where ESD Chairs Are Used

ESD seating is essential in areas where static risks need to be reduced, including:

• Electronic assembly and production
• Repair and testing stations
• Laboratories and cleanrooms
• Medical and pharmaceutical environments
• Industrial environments with static-sensitive components

Even with ESD flooring in place, many operators lift their feet or lose contact with the floor. ESD chairs help minimise these gaps and maintain consistent grounding.

Key Features of ESD Chairs

Across the range, Bondline ESD chairs offer:

• Ergonomic designs for long-term comfort
• Conductive backrests and durable metal frames
• Gas-lift height adjustments
• Static-dissipative fabric or vinyl materials
• Soft, supportive cushioning
• Easy-to-clean materials for static-sensitive environments

These features help maintain posture, improve comfort and keep EPA environments compliant.

Common Benefits

Choosing an ESD safe chair provides several advantages:

• Protects static-sensitive electronic devices
• Maintains grounding even when feet lose contact with the floor
• Improves operator comfort and productivity
• Suitable for cleanrooms and static controlled environments
• Designed for regular use in electronics and industrial settings

Types of ESD Chairs at Bondline

All chairs are manufactured in the UK with fast lead times and excellent build quality.

 Choosing the Right ESD Chair Supplier

When selecting an ESD seating supplier, consider:

• Quality – Chairs should be made from durable, conductive materials that meet strict EPA standards
• Lead times – Domestic UK manufacturing ensures faster and more reliable delivery
• Customisation – Options such as armrests, castors, glides or height variations
• Value – The right chair reduces component loss, improves safety and prevents expensive ESD damage

Bondline is a trusted UK supplier with a wide stock range and industry expertise. Our team can guide you to the most suitable ESD seating for your environment.

Frequently Asked Questions

1. What is an ESD chair used for?
An ESD chair prevents static build-up by grounding the operator and reducing the risk of electrostatic discharge in static sensitive work areas such as EPAs, labs and production lines.

2. Do ESD chairs need an ESD floor?
Yes. ESD chairs are most effective when paired with a grounded ESD floor or mat because it completes the grounding path. Without it, static may not dissipate correctly.

3. What makes a chair ESD safe?
ESD chairs include conductive materials, static-dissipative fabric or vinyl and grounded castors or glides. These features safely transfer static charge away from the operator.

4. Can an ESD chair replace a wrist strap?
No. ESD chairs support the grounding system but do not replace wrist straps, especially during seated assembly work. Both should be used together where required.

5. Are ESD chairs comfortable for long shifts?
Yes. Bondline’s ESD chairs use ergonomic designs, cushioning and adjustable features to support long hours of sitting or standing work.
