The WTRFL Perching Seat from ErgoVerse offers an angle-adjustable, contoured seating surface for both perching and leaning applications. The naturally-shaped seat features a flowing design with a softly rounded front that rises slightly to provide a "ledge" effect that can counter the "slippage" sensation that flatter seats may generate. The rounded waterfall front then drops down and away, eliminating uncomfortable sharp pressure lines against the back of the legs.
The firm polyurethane foam seat is waterproof and highly resistant to cuts or punctures, with formed channels facilitating cooling air flow. Height adjustment is accomplished with a gas spring that also serves as a shock absorber by providing a cushioning effect when weight is brought to bear. The seat angle is adjustable from 0° to 14° to let every individual find a comfortable position. A convenient handle is integrated into the back of the seat for ease of movement about the workspace. | | Ergonomic Benefits |
|---|
Reduces Risk of Lower Back Pain - Standing with the feet flat for extended periods of time (such as at a standing desk or counter) requires the muscles of the lower back to remain in a state of constant tension (even more so if the abdominal muscles are weak.) As the muscles tire, the back tends to curve or arch, which can often lead to an exaggerated degree of lordosis (sometimes referred to as "swayback"). Since some degree of unnatural curvature is already common to many back problems, a standing workstation has the potential to increase, rather than decrease, pain and fatigue. The greater elevation afforded on a stool such as the WTRFL positions the thighs at a downward angle. This alignment of the thighs naturally tilts the pelvis slightly forward, allowing the spine to return to the gently curved S-shape that provides the greatest strength, stability and support for the entire body. The unnatural, extreme curvature is eliminated, and the overworked muscles of the back are able to relax and recover. As the WTRFL can also serve well as a temporary chair it provides multiple positions that can be varied throughout the day.
Reduces Strain on Knees - Using the WTRFL in the leaning or perching mode, or as a raised stool, can significantly reduce the stress on the knee joints as little effort is needed to transition between leaning and standing fully upright. This transition between stances requires noticeably less effort than rising from a traditional chair.
Reduces Risk of Lower Limb Circulation Problems - Static standing has been identified as a contributing factor in the development of edema (swelling of the lower legs). When the muscles of the lower legs are not being flexed their ability to pump blood and fluids through the circulatory system is restricted. Leaning or sitting on the WTRFL frees one to relax and freely flex the muscles of the lower legs, encouraging better circulation.
Extends Range of Movement - A semi-standing position provides a significant increase in range of motion and reach compared to a seated position in a conventional chair or on a traditional stool. The semi-standing position extends the Comfort Zone and allows access to a larger area of the work surface, while at the same time reducing the risk of overextension. Learn More About the Comfort Zone.
Can Aid in Improving Overall Health - The conventional seated position (i.e. with a 90° bend at the hips) restricts the flow of blood and other fluids through the internal organs. A leaning or raised stool position such as the WTRFL offers can benefit the digestive and cardiovascular systems. The upright stance reduces potential constrictions in the digestive tract and, by opening up the core and allowing the diaphragm to move more freely, can significantly increase cardiovascular efficiency.
Increases Mental Alertness - The open core stance provided by the WTRFL, combined with the ability to flex the leg muscles, naturally increases oxygen intake and improves blood flow throughout the body. The increased cardiovascular efficiency facilitates more effective oxygenation of the brain and contributes to a greater degree of mental alertness.
Encourages Core Muscle Maintenance - The semi-standing or leaning stance promoted by the WTRFL helps to keep the abdominal muscles engaged as they work to keep the torso stabilized during the work session. This constant, low-level activity helps to maintain muscle tone in those muscle groups without overtiring them.
May Increase Overall Activity for Better Health - As one can move more easily between the seated, resting position and a fully standing position they may find their overall activity levels increasing as well, potentially reducing some of the risks known to be associated with extended sitting.

- Wide Range of Seat Height Adjustment: Seat is easily adjustable from 23.2" to 34.4", over 11" of range.
- Contoured Seat: The wide, formed polyurethane seat features a natural contoured shape that makes the WTRFL more appealing to sit on than some other sit-stand stools which offer smaller seating surfaces. The gently rounded waterfall front lip naturally engages body contours to ensure a comfortable and secure seating position
- Rugged Construction: The tubular steel base is built to last for many years. Simplicity of design means a lower risk of failure.
- Cushioning Gas Spring: The gas spring that provides height adjustment also serves as a shock absorber to help absorb impact when first sitting down as well as throughout the day as position is shifted
- Infinite Height Adjustment: Seat height can be easily adjusted to any point within the adjustment range using a simple hand-activated lever (similar to the mechanism on a standard office chair) to release the lock on the gas spring lift.
- Stable Base: A sturdy steel 23" diameter 5-point base ensures stability.
- Integrated Handle: The WTRFL seat has an integrated handle to facilitate easier movement of the seat when necessary.
- Tilting Seat: The WTRFL seat can be tilted forward from 0° to 14° from horizontal. Adjustment is via a locking lever that enables infinite positioning.

| | Usage Tips |
|---|
- Sitting, Leaning or Perching? First, choose whether you wish to sit, lean, or perch. Adjust the height and tilt of the seat for the greatest comfort.
- Consider Adding an Anti-Fatigue Mat. If you notice that you do not feel secure, or would like a cushioned surface on which to rest your feet, consider adding a non-slip MATAR Anti-Fatigue Mat to your workstation.
- Consider Bracing Your Feet. Bracing your feet against a sturdy, fixed bar or rail such as the SAIPH Foot Brace Rail has the potential to substantially improve your comfort when leaning against the seat. Caution: Standard footrests are not recommended for this application.
