If you are looking for a basic ergonomic chair for use in ESD areas, the ESD Unitec from bimos in Germany is a straightforward yet solid option. It offers all the standard functions and can be easily adjusted by the user.

The ESD solution for solid performance

If you are looking for a basic model for use in ESD areas, ESD Unitec is a straightforward yet solid option. It offers all the standard functions and can be easily adjusted by the user.

ESD Unitec is ideal for workplace situations that involve standing up as well as sitting down. Unitec has a generously proportioned seat and a high backrest. Comprehensive discharge capability is not a requirement for many areas. Therefore, ESD Unitec does not feature the conductive plastic components and steel components with conductive coating found on our other ESD models. Nevertheless, there is absolutely no compromise in terms of how the upholstery manages to direct electrostatic charges down to the conductive base.

The workplace and design quality of production and laboratory areas is becoming more and more demanding especially in ESD protected areas. Static electricity (electrostatic charge) can arise, if two non conductive materials are rubbed against each other and separated afterwards. Electrostatic discharges arise, when charged objects, persons or conductive materials touch each other, or get close to each other. This discharge can be absolutely critical in work areas in.......

Bimos ESD chairs fulfil the requirements of the EN 61340-5-1 standard for use in ESD protected areas (EPAs). By choosing the best possible materials and joining technologies, bimos chairs ensure that electrostatic charges can be safely eliminated. Typical discharge resistance is 106 Ω.
  • Fully integrated system - meets ESD standard DIN EN 61340-5-1
  • 5 volume conductive castors / glides - By adding carbon fiber structures, the castors / glides become conductive
  • Conductive upholsteries - The upholsteries are equipped with a special conductive tissue containing finest woven metallic threads.

ESD Plus Option:

Choose to have the back with volume conductive plastics & steel components with conductive coating. Call us for a price quote.

  • Steel components with conductive coating
  • Volume conductive plastics - The plastic is coated with carbon particles to make it conductive

Features & Benefits:


  • Large, ergonomically designed backrest to take the strain off the spine and muscles with integrated lumbar support
  • Backrest height adjustment convenient and easy to handle in sitting position
  • Healthy posture due to a hump providing support for the back in the lumbar region
  • The support area can be adapted in accordance to the user’s body size


  • Ergonomically designed seat with rounded front edge
  • The round front edge of the seat prevents blocked circulation in the thighs

Seat height:

  • Stepless seat height setting from 440-620 mm supported by safety gas spring with protective cover

Reliable electrostatic discharge protection for electronic workstations

ESD (Electro Static Discharge) refers to the electrostatic discharge of charged objects or people.
Electrostatic discharge can result in damage to microelectronics components. This is because of the minute scale involved which means that the energy from a static discharge has the same impact on a semiconductor as a lightning strike would on a tree.

ESD chairs play a crucial role when it comes to ensuring reliable ESD protective measures for electronic workstations.

ESD protection is regulated by European standard EN 61340, which is designed to help users select appropriate protective measures. It stipulates the following in respect of workplace chairs: “The resistance to the point of contact with the floor of any parts of the seat that could come into contact with the user’s body during standard use must be <1010 Ω.” (Extract from standard EN 61340-5-1)

Consistently exceeding the standard

bimos ESD chairs meet the requirements of standard EN 61340-5-1 as far as their use in EPAs (ESD Protected Areas) is concerned. However, the demands that actually apply in practice
are often more stringent even than this. This is because the increasing miniaturisation of electronics components is making them more susceptible to the problem of electrostatic discharge. The most effective way of dealing with this issue is either to prevent charges from occurring in the first place or
to ensure that any undesirable charges are safely discharged.

Thanks to the optimum choice of materials and connection technology used, bimos chairs reliably prevent the build-up of electrostatic charges. In addition, the chairs are designed to
direct any charges that the user may be carrying safely down to the conductive base as soon as he or she sits down. Thus, bimos ESD chairs offer a fully integrated system of protection.
