Chair X 20 PU ESD
A gas lift controls height adjustment. The black 
conductive  polyurethane seat and back has  a 
wear resistant and washable surface. The back 
rest  is  mechanically  adjusted.  Tilt  of  seat  and 
angle  and  height  of  back  rest  mechanically 
adjusted.  Chair  base  anodized  aluminium  in 
grey  and  black.  Conductive  swivelling  twin 
castors, which are braked when unloaded, are 
standard. Arm rests optional. 
High chairX 25 PU ESD
Construction as X 20 PU ESD, but the high chairs 
have a foot ring and conductive fl oor glides to 
improve work safety.
Stool X 10 PU
A  black  polyurethane  seat  Ø  350  mm. 
Conductive  swivelling  twin  castors,  which  are 
braked when unloaded, are standard. 
Arm rest AR ESD
The conductive arm rests have a 80mm height 
range  60  mm  width  range  and  50mm  depth 
range.  They  can  be  set  either  forwards  or 
backwards. By reversing the armrests you can sit 
closer to the workbench.
These durable industrial chairs constructed with a cushioned conductive polyurethane seat and back 
that can be washed or steam cleaned The chairs are very comfortable to sit in and offer excellent

The use of dissipative matting or fl ooring • 
is recommended. 
NOTE: To ensure good  contact clean the 
castors regularly.
