Kneeling Chairs


Balans Chair: A Balans Chair is a type of kneeling chair designed by Hans Christian Mengshoel in 1979 and believed to be the first of its kind. The frame of the Balans Chair features curved sled-style legs that allow the user to tip forward slightly for more comfortable work postures, and the frame includes two or three cushioned platforms for the seat and shins, with the shin-cushion designed as a single platform or split platform. Variations on the Balans Chair are found throughout all modern knee chair and kneeling chair styles.

Ergonomic Chairs: Ergonomic chairs are designed to fit the natural contours of the body, with angled components to provide optimal support for comfortable seating in natural, healthy postures. Ergonomic chairs often feature thick foam cushions, contoured shaping, and adjustable comfort settings such as seat-height.

Knee Chair: Knee chairs are ergonomically designed office-friendly seating elements with a two-platform layout made to support and distribute body weight under the shins and buttocks. The positioning of the cushioned platforms open the body angle from the 90° created in classic office chairs to 60° or 70° depending on the knee chair design. Knee chairs are often referred to as kneeling chairs, but body weight is supported by the shins not the knees.

Kneeling Chairs: Kneeling chairs are a set of office-friendly chairs designed to support the body beneath the buttocks and shins for weight distribution different from that of traditional chairs. The two-platform design of kneeling chairs opens the body angle by lowering the knees, changing the seating position from a 90° angle in traditional office chairs, to an open 60° to 70° angle, depending on the chair design. Kneeling chairs are sometimes referred to as knee chairs.

Black Metal Frame: A black metal frame is a metal kneeling chair frame, usually made from steel or aluminum, and finished with black paint to protect from exposure to the elements and regular use. The black metal frame is often set on casters for support and mobility to enhance use of the kneeling chair or knee chair.

Heavy-Duty Nylon Base: Select kneeling chairs are made with a heavy-duty nylon base, fashioned into a 5-prong layout and set on casters for mobility. Nylon is a durable, synthetic polymer that can be molded or shaped to form impact-resistant, highly durable components for chairs and other products. The base may be smooth or textured, depending on the design.

Knee Pad(s): Knee chairs and kneeling chairs have one or two knee pads positioned at an angle within the frame, in front of the cushioned seat. The knee pad or pads support the legs under the shins. Designed similar to the seat, knee pad components have a support platform, foam cushioning, and upholstery to match the seat and complete the chair design.

Metal Base: A Kneeling chair with a metal base has a frame comprised of metal, usually steel or aluminum, as opposed to the impact-resistant nylon or plastic bases. The metal is usually finished with a durable paint to protect from exposure and regular use.

Seat: The seat is the chair-portion of knee chairs or kneeling chairs, designed with a supporting platform and ergonomic foam cushioning. Upholstery covers the cushion and seat to complete the design.

T-Leg Base: A T-leg base generally refers to a chair frame with legs that are designed to resemble upside-down T-shapes. The casters or wheels are often attached to ends of the cross-portion of the T-shape while the stem forms the frame supporting the chair components.

Under-Seat Lever: An under-seat lever refers to the adjustable seat-height controls. Positioned for easy-reach underneath the cushioned seat in select adjustable-height knee chairs as well as traditional office chairs, the lever activates the integrated pneumatic height mechanism to adjust the seat position along a preset height-range for customized support.

Wood Base Frame: Select knee chairs are constructed with a wood frame, as opposed to the nylon or metal frame options. The wood base is set on four casters for support and convenient mobility, and the frame is finished in one of two colors to customize the look.

2½” Seat and Knee Pads: Kneeling chairs with 2½” Seat and Knee Pads are designed with a 2½”-thick seat cushion and 2½”-thick knee pad(s) to provide lasting support and comfort for the user.

3¼” Knee Pad: A 3¼” knee pad refers to the 3¼”-thick foam cushion comprising the knee pad section of select kneeling chairs.

3½” Thick Seat: A 3½” thick seat refers to the 3½”-thick foam cushion forming the seat of select knee chairs or kneeling chairs.

5-Prong Base: A 5-Prong Base refers to the mobile star-shaped base of many office chairs. Often constructed from nylon or other impact-resistant composition, the 5-Prong Base supports the main seat frame at its center, usually with an integrated pneumatic seat-height adjustment mechanism. Five prongs extend from the center, evenly spaced for balanced support of the seat and chair frame. Each prong usually contains a caster or wheel at the outer-most part, supporting the weight of the chair and user, while providing mobility as desired. A 5-Prong Base is usually made with a diameter equal to or greater than the seat to ensure balance and stability.

Ergonomic Shaping:Ergonomic shaping indicates the use of comfort-enhancing features to improve the natural fit, feel, and use of kneeling chairs. Ergonomic shaping can refer to molded foam cushions that fit the natural shape of the body for better support and lasting comfort. Ergonomic shaping can also refer to the layout of the kneeling chair frame, the angle and orientation of different chair components, and the use of adjustable comfort settings to enhance performance.

Memory Foam: Memory foam is a foam cushion designed using polyurethane that is chemically enhanced for increased density and viscosity, making the foam soften quickly from body heat to conform to the body’s nature shape. Memory foam also recovers fast to return to and retain its original shaping for lasting quality performance.

Wood Frame Finish: Wood frame finish refers to the color options for kneeling chairs with wood base frames. The wood is finished in a classic mahogany color or black to meet different decorative needs in contemporary style.


Adjustable Height: Adjustable height indicates the ability to personalize the knee chair or kneeling chair by positioning the seat at a desired height within a preset height-range. The adjustable seat height-range may be from 18” to 23” or 20” to 28”, or other comparable height-range, depending on the chair design and unique ergonomic features.

Coccyx Pain, Tailbone Pain: Coccyx or tailbone pain refers to aching at the base of the spine, usually centered and resulting from significant pressure in less ergonomic body regions. Poor seat cushioning, improper spine alignment, unhealthy sitting positions and postures, and fixed-height or poorly configured adjustable-height seating can all contribute to tailbone pressure and pain. Kneeling chairs are designed to support the body weight under the buttocks and shins, reducing some pressure on the spine and rear and helping alleviate tailbone pain experienced with many traditional office chairs.

Divided Body Weight, Distributed Body Weight: Divided or distributed body weight refers to the two-platform or three-platform layout of kneeling chairs, with the body weight supported under the buttocks and shins. While the majority of weight remains in the rear, the angled positions of the seat and knee pads and the distributed weight between them helps reduce aches and pains commonly associated with classic-style office seating.

Limited Warranty, Limited 5-Year Warranty: A limited warranty indicates the warranty from the manufacturer covers some but not all issues that may arise in a specified time period after purchase of the kneeling chair. A limited 5-year warranty, for example, will cover defects and select issues with a kneeling chair for up to 5 years from the purchase date. Each kneeling chair comes with all the necessary manufacturer warranty information.

Manual Seat Height Adjustment: Manual seat height adjustment indicates a non-pneumatic adjustable seat-height that is adjusted along a preset height-range either by the use of a tool, such as a ratchet, or other manual controls. The manual seat height adjustment feature provides a more rigid support structure often associated with fewer or less frequent readjustments during use.

Open Body Angle: Kneeling chairs provide an open body angle seating position, with the cushioned seat and knee pad platforms angled to allow the knees to rest lower than the hips, opening the front-facing body angle, usually to an angle between 60° or 70°.

Pneumatic Seat Height: Pneumatic seat height indicates the use of an integrated gas lift mechanism, activated by the touch of an under-seat lever, and used to control the height of the cushioned seat in select kneeling chairs. The seat-height will adjust along a preset height-range, usually between 18”H and 23”H, but usually varying between chair designs.

Reduced Back Strain: Kneeling chairs are ergonomically designed to help improve comfort and reduce back strain associated with traditional office seating. The open body angle, distributed support under the shins and buttocks, and the improved spine alignment supported by knee chairs can reduce pressure on the spine and back muscles, help stabilize core muscles for support, and reduce common aches and pains, particularly in the back.

Ships Flat: Kneeling chairs often ship flat, in a box, ready for assembly before use. The flat shipping carton reduces shipping costs.

Shins: Shins refer to the larger bone in the front of the lower-leg beneath the knees; the tibia. Although called knee pads, the cushioned platform(s) in front of the seat in kneeling chairs are designed to support the body under the shins, not the knees.

Spine Alignment: Spine alignment refers to proper sitting postures that keep the head, neck, shoulders, spine, and hips in a healthy alignment to reduce back pain, tension aches, and other office work-associated conditions that can affect comfort, health, and productivity. Kneeling chairs are designed to support the body comfortably under the shins and buttocks while allowing the user to remain in a healthy position for good spine alignment.

Tools Needed for Assembly: Kneeling chairs that indicate tools are needed for assembly will include all the necessary components for the kneeling chair but require the use of common tools, such as a screwdriver, for assembly.

Upholstery Warranty, 3-Year Upholstery Warranty: An upholstery warranty refers to a separate warranty that covers only damage or defects to the upholstery of a kneeling chair during a specified time period. A 3-year upholstery warranty, for example, will cover select issues with upholstery on a given kneeling chair for up to 3 years from the purchase date. All manufacturer warranty information is included with each kneeling chair.

2-Person Setup: Kneeling chairs that specify a need for 2-person setup may require two people to safely assemble the chair. This is a safety precaution and to prevent injury and ensure safe, stable setup for consistent quality use of the kneeling chair.

60° to 70° Open Body Angle: A 60° to 70° open body angle refers to the front-facing body angle created when sitting in a kneeling chair. With the cushioned seat and knee platforms, the knees are able to rest lower then the hips, adjusting the angle created while sitting and often associated with greater workday comfort and reduced pressure on the hips and spine.

90° Standard Body Angle: A 90° standard body angle refers to the 90° angle created by sitting in a classic-style office chair, with spine straight and thighs parallel to the floor.
