Why 5 seat sizes?
One size does not fit all. The #5 seat accommodates most individuals because of the average size and contouring. The #6 seat is slightly larger and offers additional contouring for added comfort and support. The #7 seat is deeply contoured for reduced buttock/thigh pressure and added comfort. The #4 seat is specifically designed for the smaller population who require a smaller or narrower seat. The #8 seat supports individuals requiring a wider and/or longer seat pan.
Why 3 backrests sizes?
Different body sizes and different tasks. Backrests differ not only for varying body sizes, but for varying tasks as well. The #5 backrest accommodates the majority of users by providing exceptional back and lumbar support in an average size. This backrest is used when there is greater movement in the upper body: (i.e. assembly line workers, bank tellers, etc.) The larger backrest, the #8, provides superior lateral, upper back and lumbar support. This backrest comes with or without an additional two-way adjustable headrest. The #6 backrest provides a high, wide back with less lateral curve.
What type of foam do you use?
All Neutral Posture® chairs utilize various densities and thicknesses of foam that have been carefully pressure-mapped to provide optimum seated comfort by significantly reducing buttock/thigh pressure. Along with our multi-density foam, our revolutionary new knitted fabric, "Cloud 9™", makes it one of the most comfortable chairs on the market.
Will I ever learn to use all of these adjustments?
Each chair comes with our Chair Adjustment Guide, located conveniently on a pull-out tab within the underside of the right arm pad displaying all of the chair adjustments and always within easy reach. No more worries about lost owners manuals.
To further explain the adjustments on your Neutral Posture® Chair, you can view Adjustment Guide videos online that show you how to use each adjustment and why. With proper training and ergonomic explanations behind each feature, the adjustments should become simple and automatic.
Is there proof that the Neutral Posture® chair will increase productivity?
There are several different studies that support this increase. The dissertation on the chair's design, by Jerome J. Congleton, Ph.D., P.E., C.P.E., shows an increase in productivity ranging from 4% to 10%. A 4% increase is used on the cost justification forms because it is the lowest productivity increase found. Independent studies have shown an 8% increase across the board.
Is there any other independent research done on the Neutral Posture® chairs?
Absolutely, Yes! We are so proud to provide users with the best in ergonomic seating, we welcome others to test our products to see for themselves why we are the best. The State of Washington found a 90% reduction in workers comp costs and a 60% overall injury reduction.4 Texas A&M compared our chair with some of the world's leading manufacturers and our Neutral Posture® chair surpassed all others with a significant reduction in seated pressure.5 The IRS found that with the use of Neutral Posture® chairs, employee pain and discomfort were significantly reduced. This led to significant reductions in training costs for replacement workers, medical expenses and sick leave.6
Do your chairs meet ANSI/BIFMA standards?
Of Course, Yes. All Neutral Posture® chairs have been tested and exceed the ANSI/BIFMA X5.1-1993 standards and meet or exceed the ANSI/HFS 100-1988 requirements.
Are other options available on the armrests?
Yes, Several Options! Our standard height and width adjustable armrest has a surface length of 10" and a 360° swivel. This allows
the user to position the armrest at any angle, for continuous support at any task. Other armrest styles including Oversized Extra
Soft (OES), non-adjustable loop arms and Gel pads are available.
What about special needs?
The basis of the standard Neutral Posture® chair design is to accommodate a range of males and females. (This range is based on the 5th percentile female body measurements to the 95th percentile male body measurements.) This leaves only 5% of the population, which we do not ideally accommodate; therefore, some special modifications are necessary. All ideas and specifications must be discussed with the engineering department. After approval, pricing and availability will be determined.
Big and Tall seating: Our Model 10100 accommodates individuals up to 7' tall and/or 500lbs.
Why is the Neutral Posture® chair design better than traditional 90° posture recommended by some other chair manufacturers?
The Neutral Posture® chair design places the body in a non-stressed posture. There is no pushing or pulling of the muscles, tendons or ligaments. In a stress-free position, vertebrae are evenly spaced and properly aligned along the spine, which reduces the risk of displaced discs. The 90° angle theory is based on old research, which has been proven incorrect because it takes too much muscular energy to maintain this posture for long periods of time. The muscles along the buttock and thigh area are being stretched which results in slumping to alleviate the stress and pressure. Slumping, in turn, places pressure on the lumbar area because it is not properly supported and the vertebrae are no longer evenly spaced.
Does Neutral Posture offer any other ergonomic products?
Neutral Posture Lite™ Seating line offers practical task and executive seating at a more economical price. Our new Nhancements accessory line, offers a vast array of keyboard, monitor lifts, CPU holders and footrests to complete your ergonomic work station.
