ESD bench vs floor matting: M3 vs M4
M3 and M4 are the two ESD mats in Maximum Matting's M-Series. Both are static-dissipative and built for electrostatic protected areas — but one goes on the bench and one goes on the floor. The short version: M3 for the work surface, M4 for the standing floor. They're often used together in one EPA workstation.

Choose M3 if…
- You need a static-safe SURFACE on a bench or table
- Fine work on sensitive components: PCBs, parts, repairs
- Electronics labs, component assembly, inspection benches
- Operators sit or work seated and are grounded via a wrist strap
Popular: 60 cm x 45 cm Blue — £27.00
Choose M4 if…
- Operators STAND in an EPA and need anti-fatigue comfort
- A grounded floor across electronics manufacturing or testing
- Technical rooms and static-controlled standing workstations
- Operators grounded via a shoe heel grounder while standing
Popular: 60 cm x 91 cm Grey — £45.05
Not either/or: a fully protected EPA workstation often runs a grounded M3 bench mat and a grounded M4 floor mat together — the bench keeps components safe while the floor keeps the standing operator at the same potential.
Make it work
Grounding and format both matter
Grounding: an ESD mat only protects when it is bonded to ground. Connect the mat to a common ground point with a grounding cord — ring- or socket-terminal versions — and an earth bonding plug, available in UK and Continental/EU formats. Ground the operator too: an antistatic wrist strap suits seated bench work on M3, while a shoe heel grounder suits operators standing on M4. Our ESD mat grounding setup guide walks through the full bonding chain.
Format: M3 and M4 both come as fixed-size Standard Mats, as Cut to Length per linear metre for long bench runs or aisles, and as an ESD Kit that bundles the mat with the grounding accessories. If you're setting up a complete bench, the M3 workstation guide covers a full electronics assembly setup.
Need to size up the floor area? Our sizing & coverage guide helps you measure up, and the surface types explained guide compares smooth, bubble, and the rest. For the comfort-only mats, see M1 vs M2, or browse the full range on the M-Series overview.
FAQ
Common questions
What's the difference between an ESD bench mat and an ESD floor mat?
An ESD bench mat (M3) sits on a workbench or table to give a static-safe surface for fine work on sensitive components — electronics labs, PCB and component assembly, repair and inspection benches. An ESD floor mat (M4) goes on the floor of a static-controlled standing area and adds anti-fatigue comfort as well as a grounded floor, for electronics manufacturing, testing, and technical rooms. M3 is the surface you work on; M4 is the surface you stand on. They are often used together in one EPA workstation.
Do ESD mats need to be grounded to work?
Yes. An ESD mat only dissipates static when it is grounded. Connect the mat to a common ground point using a grounding cord (available with ring- or socket-terminal versions) and an earth bonding plug (UK and Continental/EU formats). Operators are typically grounded too, via an antistatic wrist strap at the bench or a shoe heel grounder when standing on the floor mat.
What's included in an ESD Kit?
The ESD Kit format bundles the mat (M3 or M4) together with the grounding accessories needed to put it into service, so you get a static-dissipative surface and the means to bond it to ground in one order. M3 and M4 are also available as a Standard Mat in fixed sizes and as Cut to Length per linear metre.
What resistance range and standard do M3 and M4 meet?
Both M3 and M4 are ESD compliant in the static-dissipative range of 10^6 to 10^9 ohms and are intended for use in electrostatic protected areas (EPAs) aligned with IEC 61340-5-1 practice. Grounding the mat is what keeps it within that working range in use.
