Most BenchPro™ cleanroom seating meets or exceed ISO Class 3. View Complete Testing Results and standards information.

General Information: The higher the Class number, the more particulate is acceptable. i.e. Class 100,000 allows 100,000 particles, where Class 3 allows 3.

BenchPro™ seating products have been independently tested to the following cleanroom standards:

ISO 14644-1 – Classification of Air Cleanliness.
ISO 14644-3 – Test Methods.
IES-RP-CC006.2 – Testing Cleanrooms.
BenchPro™ cleanroom chair components are wiped down with alcohol prior to packaging, then double bagged and boxed.

Foam Construction: 2.7” Thick Five density foam set. The top layer is Memory Foam for exceptional comfort, under that is soft foam to maximize comfort for lighter weight persons, then Medium Density followed by extra firm foam for the heavier persons. Under this is a special firm foam with a cut-out pattern in the center to protect the exclusive internal 3M™ filter system from excessive compression.

Filtration: BenchPro™ Cleanroom Seating Products Exclusively Use 3M Filters for Absolute Dependability.

Chair Quality

BenchPro™ offers a 10-year unconditional warranty on our seating . . . .because we can.

We make sure the chairs are well built, and the fabrics and foams we use will last longer than 10-years of heavy use.

Example: Seat plates (under the seat cushion) are made for sale in at least 10 countries. We have tested each one of these and found them too weak to pass BIFMA and our standards, so we made all the tooling to produce the parts, and make our own. We sell them to a few other quality chair manufacturers.

While other brands have pressed together and crimped connections, ours use better methods and are assembled by welding. These photos show 24 mig spot welds and 2 circular mig welds. Then we powder paint them.

We carry liability insurance. It has never been used!
