EVERY 157E Series High Back Chair

The EVERY 157E Series High Back Task Chair from Interstuhl is designed for comfort and support, especially for those who require a higher back rest or are looking for a firm and supportive chair. The standard synchronous movement features a large opening angle (up to 120°) that can be left unrestrained when freedom of movement is desired. For times when a more fixed position is required, the back rest is easily locked at the 90° or 120° points.

The back rest and seat on the EVERY 157E are fully upholstered with breathable fabric over firm but comfortable cushioning so those who prefer a firmer or more supportive back rest will not be disappointed. The 24.5" high back rest frame has a built-in lumbar curve which can be fine-tuned or enhanced using the height-adjustable, sliding lumbar support. The firmness or degree of the lumbar support can also be adjusted using a knob on the rear of the back rest. The seat pan has 2" of depth adjustment (16.5" to 18.5") so each person can adjust it for their build and the absence of glue between the fabric and the foam ensures optimal airflow in both the back rest and seat.

Arm support is provided by highly-adjustable 4D T-armrests that can move in four separate directions: up and down, left and right, forward and backward and swivel (15° in or out). Most individuals, regardless of size or build, should be able to achieve the support necessary to minimize strain on their shoulders and neck.

Rounding out the EVERY 157E are soft double casters for use on hard-surface flooring and a premium Polished Aluminum base.

• High Back for Support: The EVERY 157E features a comfortably cushioned back rest upholstered in breathable Lucia 58 fabric. The 24.5" tall back rest offers firm back and shoulder support whether sitting upright or reclining, even for taller individuals who may find back rests on most task chairs lacking in this regard.
• Synchronous Movement: The EVERY 157E features a synchronous movement that tilts the seat slightly as the angle of the chair opens up.
• Comfortable Breathable Seat Cushion: The EVERY is equipped with 2" of foam for comfort and support. The Lucia fabric upholstery is unglued, ensuring optimal air movement and comfort.
• Free Moving Back Rest: The back rest on the EVERY 157E can angle to provide an opening angle of anywhere between 90° and approximately 120°. This offers a wide range of movement to those who wish to be more active throughout the day.
• Back Rest Lock Option: Back rest angle can be locked to either a 90° upright position when working on projects that require a more fixed and focused position, or at approximately 120° when a more relaxed reclining position is desired.
• Adjustable Lumbar Support: The EVERY 157E is equipped with a sliding lumbar support that can be adjusted within a 2" vertical range. The pressure level of the lumbar support can be adjusted using the knob on the back of the chair. The EVERY 157E also has a basic lumbar curve built into the back rest frame, providing a basic foundation for the adjustable aspects of the lumbar support.
• Load-Dependent Casters for Hard Floors: The EVERY 157E is equipped with soft 65 mm load-dependent casters for safety. This means that the chair will not roll away when unoccupied. These casters do not lock, they only exert just enough resistance so that the chair does not roll on its own when weight is removed. It is still possible to re-position the chair with minimal effort. When the chair is occupied the brake fully disengages, permitting virtually effortless chair movement.
• Depth Adjustable Seat: The EVERY 157E features a sliding seatpan which provides a 2" range of depth adjustment able to accommodate the seat-depth requirements of a wide range of individuals. To ensure that arm support is suitably positioned the armrests follow the movement of the seatpan.
• "Waterfall Front" Seatpan: EVERY 157E chairs are equipped with a "waterfall" front to reduce the risk of unnecessary pressure being exerted against the back of the thighs.
• Removable 4-D Armrests: The EVERY features 4-D Armrests that are adjustable for height, width (from the inner edge of the left armrest to the inner edge of the right armrest), depth (forward and backward), and pivot (10° to the left and right). See "Specifications" below for detailed range of movement. If desired the armrests can easily be detached using a simple Allen key.

• Adjust the armrests to match your build - The armrests on the EVERY offer an adjustment range that fits a vast range of heights and builds. Adjust the height, width and depth to provide support when your shoulders are relaxed and your arms are hanging at your sides. If necessary, you can adjust the angle of the armrest to approximately 15° (in or out) to match the angle at which your forearms approach your workspace.
• Adjust the lumbar support height and pressure to your personal preferences. You want the support to be positioned centrally in the curve of your back. When adjusting the pressure you want to have a degree of firmness but should not feel that the lumbar support is pressing into your back.
• Ensure that the seat pan is correctly adjusted to match your body. When comfortably seated with your back resting against the backrest you want to have 1-2 finger widths between the back of your knees and the front of the seatpan. Too little space may restrict circulation; too much space will not provide the optimal support.
• Set the height of the EVERY chair correctly. Aim for an elevation that lets your elbows open slightly more than 90° when your hands are resting on the keyboard or mouse. If the chair is too low the angle between your legs and torso will be less than 90°. Make sure the seat is high enough to create a 90° angle at the hips. Note: You might also need to raise the height of the keyboard and mousing surfaces accordingly. If the greater elevation results in your feet being unable to rest flat against the floor you should consider adding a footrest to your workstation.
