EV45 ESD Lab Stool
The affordable Office EV45 ESD lab stool is configured by Pacific Ergonomics — 25+ years of specifying lab seating for universities, ESD facilities, and production environments nationwide.
This ESD lab stool is ideal for budget-conscious labs and teams with petite or mixed-build users. The EV45 provides full ESD protection in the vinyl, the frame and arms. It is also fully adjustable. It can also be configured for a bench height version without the footring.
We start with your bench height, cleaning protocol, floor type, static control requirements, and who is using the chair — then configure the right solution, place the order, and get it to you anywhere in the U.S. with a showroom in San Diego, CA, area in the city of Escondido.
Description
ESD Lab Stool Configurations for Every Application
The OM EV45 ESD lab stool is an affordable option with adjustability with a smooth surface that is easy to clean. Pacific Ergonomics helps you identify the right configuration before you order —the ESD material on the chair, the type of arms, caster type, cylinder range and more to ensure it is right for your needs.
Budget-Friendly Lab Stool with Real Adjustability?
Most budget lab stools sacrifice adjustability. The EV45 keeps seat height, seat depth, and back angle all independently adjustable — so users at different heights and bench configurations can get the right fit without compromising comfort during a long shift.
Well-suited for general labs, clinical environments, and any application where multiple users share seating. One size accommodates a wide range of body types, including petite users.
Need a Good Value ESD Lab Stool for Static-Sensitive Bench Work?
The EV45 ESD chair uses a static-dissipative surface to protect sensitive components and equipment at electronics assembly benches, semiconductor workstations, and other ESD-controlled environments. Pacific Ergonomics confirms the resistance values and grounding path before the order is placed — not after.
Ask us about caster and glide options for ESD flooring — the wrong caster can break the grounding path entirely.

How the EV45 ESD Lab Stool Adjusts
Four independent adjustments let each user set up the lab stool for their body and their bench — without one adjustment forcing a compromise on another.
Seat Height
Pneumatic lift adjusts to match the bench height — standard or elevated configurations. Confirm your bench height before ordering so we specify the right cylinder range.
Seat Slider
The seat slides forward and back independently of the backrest, so users can adjust seat depth to match leg length without touching back angle. Particularly useful in environments with a mix of petite and average-height users sharing the same chair.
Back Tilt and Lock
The backrest tilts and locks at the preferred angle — useful for users who want support in a fixed position rather than free-float movement during focused bench work.
Independent Back Angle
Back angle adjusts separately from seat recline, letting users set lumbar contact and backrest pitch without changing seat position. This matters most in shared-use environments where multiple people use the same chair across shifts.
Pacific Ergonomics also provides ergonomic lab assessments and industrial ergonomic assessments as separate services — full evaluations of workstation types, postures, tasks performed, and MSD risk across your lab or production floor. If your team is experiencing discomfort or injuries, an assessment identifies exactly where the risk is before you spend on solutions.

Frequently Asked Questions
Is an affordable ESD lab stool suitable for multiple bench heights?
Yes. Pacific Ergonomics offers an adjustable ESD lab stool that is for 30-inch, 36-inch, and 42-inch bench heights. Our team helps configure the correct cylinder and footring for ergonomic comfort and proper posture at each work surface.
Does the EV45 use a grounding chain to support the ESD protection?
The ESD lab stool uses a static-dissipative surface designed to safely channel static electricity to ground, protecting sensitive components at electronics and semiconductor benches. The rest of the chair — adjustability, footring, arm options — is the same across both versions. We confirm the ESD resistance values and grounding path before your order is placed. There is an ESD chain.
Is the EV45 a good fit for petite users?
Yes it has a smaller seat pan- that is ideal when demographics of your team are more petite.
Do you offer quick shipping?
Average time to order is three weeks, and some configurations we can do this faster.
