Description
Bad Backs is licensed to sell the HermanMiller® Chair range in NSW (excluding ACT), QLD, VIC & WA.
Mirra 2 TriFlex Back is a great office chair design from market leader Herman Miller.
Based on the original Mirra Design, the Mirra 2 is leaner, lighter and sleaker and has been designed to move and flex with every movement you make. The flexible, Triflex back supports your complete spine and its size, posture, and movements. The AireWeave 2 seat-suspension material, FlexFront™ adjustable seat depth, and redesigned Harmonic™ tilt are just some of the features on this chair. The TriFlex allows more rigorous cleaning protocols because there is no fabric layer.
Unique Back Support
The AireWeave™ 2 seat-suspension material is the result of creative design by merging a fabric layer with polymer veins to create a unique structure that supports and moves with the user, and keeps you in healthy alignment.
A Balanced Ride - Naturally.
The Mirra 2's reinvented Harmonic tilt and creates a smooth and balanced feel as you move from one position to another regardless of your size or frame. Pivot points are at the user's hip, knee, and ankle for easy, natural motion, and the backrest and seat move in proper relation for the correct support in all seated positions.
Seat Comfort
Mirra 2's breathable AireWeave seat-suspension material conforms to each sitter's shape and size and distributes pressure evenly.
Sleek Contemporary Design
Redesigned by Studio 7.5 in Berlin, Germany, Mirra 2 brings a fresh modern contemporary look to the original Mirra.
Environmentally Friendly
The Mirra 2 chair is over 25% lighter than the original Mirra, and has a carbon footprint 25% smaller. This helps Herman Miller reach its goal of sustainable design. It's made of a minimal number of parts and is easily disassembled for recycling.
The Mirra 2 Chair is up to 93 percent recyclable based on availability of recycling facilities. Mirra 2 is comprised of 46-percent recycled materials. The recycled content breaks down by 21-percent post-consumer and 25-percent pre-consumer content.
Level® Certification - Mirra 2 is certified level 3. The level mark attests that Mirra 2, the Herman Miller GreenHouse, and Herman Miller, have been evaluated against themulti-attribute criteria of the ANSI/BIFMA e3 Furniture Sustainability Standard.
Cradle to Cradle Certified - CM Mirra 2 is Cradle to Cradle Certified CM Silver. This means that Mirra has been evaluated for its material health, and is designed for material reuse in a closed loop system, such as recycling or composting. It is assembled using 100% renewable energy.
GREENGUARD® Certified - The Mirra 2 Chair has achieved GREENGUARD® Gold certification. GREENGUARD Certified products are certified to GREENGUARD standards for low chemical emissions into indoor air during product usage.
Material Content - The Mirra 2 Chair’s components are constructed from plastic, aluminum, steel, epoxy, fabric, and foam.
Adjusting Your Mirra 2 Chair:
- Seat height
Mirra's pneumatic lift accommodates a spectrum of users. There are three adjustment ranges to choose from: the 16-201/2-inch range is for average sizes; the 16-211/2-inch range is for larger sizes; the 15-191/2-inch range fits smaller people.
- Seat depth
The FlexFront edge adjusts the front edge of the seat in a 2-inch range. Unlike sliding seat pans, there’s never a gap between the seat and back.
- Forward seat angle
For intensive work postures, the seat angle can adjust 4 degrees forward.
- Lumbar support
Adjustable lumbar support
- Armrest height, width, and angle
Each armrest adjusts in a 4-inch height range and 13/8-inch width range. Armrests pivot 11 degrees inward for keyboarding and 11 degrees outward for mousing.
- Tilt tension
This adjustment lets you control the resistance felt when you lean back. The control is side-mounted so it's easy to reach, and it takes just nine revolutions to adjust it from minimum to maximum tension.
- Tilt limiter
The five-position limiter lets you control how far the chair reclines without locking the tilt mechanism.
