Kanewell Twin Adjustable Saddle Stool in Vinyl

by Kanewell

The Twin Adjustable Saddle Stool from Kanewell provides a comfortable split-saddle seat with the added benefit of width and angle adjustment for a personalized fit. This seat is well-suited for use in active office environments, at raised counters or elevated workstations, or anywhere an individual needs to be able to move into close proximity to the work zone—such as dental, medical, or veterinary practices. The upright posture provided by the saddle-seating encourages better back posture, provides a much greater range of movement than that available from traditional seats, and enables virtually effortless movement about a workspace. The split-saddle is designed to reduce pressure points and improve airflow for a cooler and more comfortable experience, especially during longer periods of concentrated work. The Kanewell Twin Adjustable Saddle Stool has a slightly narrower profile than similar split saddles, a feature that may offer greater comfort to those with larger thighs. Kanewell Adjustable Twin Saddle Stools are well-cushioned to offer comfort even to individuals who may have a more pronounced bone structure.

The Twin Adjustable Saddle Stool in Vinyl from Kanewell features a thick layer of polyurethane foam which creates a firm but cushioned seating surface. Quality Vinyl upholstery provides a highly durable and easily cleanable surface. Unlike Leather and Polyurethane surfaces that are permeable and therefore less easily cleaned, Vinyl is waterproof and resistant to most common cleaners and disinfectant formulations, making it an ideal solution for environments where cleaning or disinfecting may be necessary. Large diameter casters offer smooth movement about the workspace. All three heights of the Kanewell are avaialble in Black Vinyl, with the Medium Cylinder version now also available in Teal or Wine (while supplies last).

The seat halves are adjustable for separation and angle of splay, and the seat as a whole can be tilted downward in the front as desired. With three models available, each offering a different height range, there is a Kanewell Adjustable Twin Saddle Stool in Vinyl to accommodate individuals ranging from 4'4" up to well over 6'. For those whose body dimensions are average proportions the suggested height ranges will work well in making a model selection. However, if an individual happens to have shorter or longer than average leg length for their height that difference in leg length needs to be taken into consideration and may require selection of a shorter or taller model if their height is close to the upper or lower end of a range. Although backrests are not generally recommended with Saddle Seats there are some circumstances where a backrest may be desired. The Kanewell Twin Adjustable Saddle Chair with Articulating Backrest combines all of the benefits of the Kanewell Saddles with the added feature of an adjustable backrest.

Optional accessories include the 360° Arm Accessory, an adjustable and repositionable Arm/Body/Elbow support that can be of value in any situation where an individual is required to lean away from an upright position for any length of time, such as in a dental office. The Footring Accessory option can be used to provide stability and comfortable support when the chair is elevated above standard heights (the height of the footring is adjustable independently of the height of the chair) and there are optional fixed glides to replace the casters if chair movement is undesirable.
Note: The Vinyl version of the Kanewell Saddle Stool is equipped with a cast aluminum base as shown in the image gallery, not the chromed steel base shown in the 3-D Virtual Interactive Product.

Ergonomic Benefits

Adjustable Width, Splay & Tilt - Kanewell Twin Adjustable Saddle Stools offer the freedom to adjust the width of the seat and change the splay of the halves so that each persons can customize the seat to their personal preference. The infinitely variable forward tilt can reduce pressure in the lower pelvic regions - of benefit to those who lean forward as part of their work.

Correct Spinal Alignment (Improved Posture) - Kanewell Twin Adjustable Saddle Stools are designed to restore the correct alignment of the spine . This is accomplished when the pelvis is tipped forward due to the 45° downward angle of the thighs. The forward tilt of the pelvis restores the natural S-Curve of the spine, positioning it where it can best provide the support necessary for the torso, neck and head. Traditional chair seats actually force the lumbar portion of the spine outward (creating a C-Curve), exerting unnatural and unsupported stress on the soft tissue muscles and ligaments of the lower back. The improved alignment of the spine which Kanewell Saddles promote alleviates or removes that stress, reducing fatigue by enabling those tissues to relax and rest. Fixed saddle seats eliminate the option of enhancing this forward tilt of the pelvis to a greater degree.

Improves Range of Reach and Increases Torso Stability - Kanewell Saddle Stools can provide a significant improvement in overall sitting posture, especially for those who need to perform dextrous movements with their hands while keeping their eyes positioned close to their work. Dental Professionals are a good example of this. Because the thighs are splayed and angling downwards rather than directly in front of them (i.e. 90°) it is now possible for them to move significantly closer to the patient. This enables the clinician to position themselves over the patient while still maintaining their torso in a stable, mostly-upright posture. This posture can greatly reduce the strain on the lower back - an issue which is common to this occupation or to anyone else who performs repetitive forward or side-reaching tasks where they must hold themselves in an outstretched position while performing a task. The forward tilt feature of the Kanewell Saddle Stool can aid in moving the torso even closer to the work area or patient/client as the pelvis rotates further forward, carrying the torso forward with that tilt. Because clinicians no longer have to focus on maintaining an awkward position they are better able to focus on their work. In addition, the closer positioning also facilitates a greater degree of hand and finger control since the arms can be held closer in to the body in a more relaxed and neutral position. This also enables them to exert greater force when necessary while at the same time reducing the effort required.

Reduced Potential for Lower Back Pain - By positioning the spine in its naturally strongest and correctly aligned position, the continuous tension and stress that traditional chairs place on the lumbar portion of the spine is relieved. Kanewell Saddles ensure that individuals are able to sit upright, rather than leaning forward from the waist. This can significantly reduce the strain to the ligaments and muscles of the lower back which in turn will reduce the risk of muscle spasms that can arise when muscle tension is maintained for too long. This will generally result in a reduction or elimination of associated back pain.

Reduced "Overreach" - A complaint commonly associated with traditional seating is that it is difficult to reach items positioned to the sides or front. Doing so requires a significant rotation forward or outward from the shoulders, often combined with a forward bend from the waist. This can be a cause for concern for two reasons. First, the extreme reaching of the arms and the high degree of rotation necessary to accomplish this can lead to the development of shoulder-related issues. Usually this is addressed by trying to adapt the work area by bringing frequently used items and equipment closer. However, there is always a limitation to the individual's comfort zone so this is usually only partially effective as a solution. The second area of concern related to the overreach is that when items are out of reach, attempts will be made to extend the limited range of the arms by bending or stretching forward from the waist. This exerts unnatural and unnecessary stress on the lower back, increasing the potential for development of lower back pain.

Kanewell Saddle Stools address both of these concerns by providing a significantly increased reaching zone. The forward tilt of the pelvis immediately provides several inches of additional forward reach that cannot be available when seated in a traditional chair. This is due to the fact that on a properly elevated saddle seat the upper body is brought into closer proximity to the work space. In combination with this is the fact that a saddle stool position permits the entire torso to accomplish the reach, rather than relying on a single joint such as the shoulder or the lower lumbar area. By spreading the reaching movement throughout the upper body not only is it possible to reduce the angle of the shoulder rotation but also the potential for stress on the lower back. The result of this is that the reach of an average person can easily and comfortably be extended 12" - 18" beyond what they could normally reach from a traditional chair.

Achieve Sit/Stand Benefits WITHOUT Standing - The upright posture achievable with saddle stools can help realize many of the benefits attributed to an active standing posture without some of the accompanying concerns and behavioural modifications. Posture is improved, circulation is increased due to the greater degree of movement offered, and oxygenation of the blood is increased as the upright posture encourages deeper breathing. This automatically results in a greater degree of alertness and the ability to better focus on the tasks at hand. As well, the leg muscles are not held in tension and can be readily flexed, reducing the potential for blood to pool in the calves.

Avoids the Risk Factors of Standing When Working - The popularity of working while standing has risen dramatically in recent years due to solid scientific evidence that extended sitting in the traditional office environment greatly increases numerous health risks. Media coverage which has to a great extent fueled this movement has almost solely focused on the potential benefits of standing to work, ignoring the equally compelling evidence that extended standing can also be extremely detrimental to overall health. Studies have shown that extended standing can result in blood pooling in the lower legs due to the static state of the leg muscles, resulting in edema (swelling of the feet and lower legs) and a corresponding increase in varicose vein problems. This also increases the load on the circulatory system which has to push this pooled blood back out of the legs. There is good evidence that this can exacerbate existing, or possibly lead to, heart and circulatory problems. Many people who stand extensively, especially on hard floors (concrete, ceramic tile, etc), also develop heel problems that can manifest as bone spurs or plantar fasciitis. Standing is also more tiring, something which has been well-known in industry for many years. While standing does burn more calories it is also rated to consume 20% more energy than sitting which can result in fatigue. Industry has addressed this by providing anti-fatigue mats, anti-fatigue footwear, and chairs to sit on during rest breaks - each of which is aimed to reduce the tiring effects of standing. Kanewell Saddle Stools enable individuals to maintain the upright posture that is most beneficial to their health while at the same time reducing their exposure to the risk factors described above. Since the saddle stool carries the majority of the weight load the leg muscles are no longer required to remain in tension mode in order to provide support. Instead, these muscles are now free to relax and flex as needed to move the chair around the work area. This movement activates the pumping action that aids in moving blood from the lower legs. By transferring the majority of the weight to the saddle seat, the feet are also permitted to rest, reducing the ongoing strain that occurs with extended static standing

IMPORTANT NOTE - Working in a Saddle Seat will generally require some modifications to the workstation. Since it elevates the torso there will be a requirement to ensure that keyboard, mouse and monitor are all able to be brought into an appropriate height position in order to maintain a neutral posture for the hands, arms, and neck. For average or shorter individuals this might be able to be accomplished by elevating the desk using specialized lifters such as Raise-Its to safely raise a desk by up to 3". Standard keyboard arms and trays may also provide enough elevation or may be utilized in combination with a product like the Raise-Its. The monitor mount may have enough range to elevate the screen to the desired greater height or a few simple monitor risers in combination with its integral movement may provide the necessary elevation. For more complex scenarios such as where the worker is taller than average it may be necessary to provide an elevating workstation that can be raised enough to bring these devices into the correct alignment. The advantage that a Saddle Seat offers over a Sit/Stand workstation is that the saddle offers a fixed seated position and the monitor and keyboard do not need to shift throughout the day as the range of motion and viewing angles do not change.
In order to properly equip a true Sit/Stand Workstation it would need to accommodate the changes which occur when switching from Sitting to Standing. These include small but significant changes in the hand/arm positions and more significant changes in the viewing angle required for the monitor. This may often require a monitor arm with a fairly wide range of elevation adjustment, adding additional cost to the adaptation.

Features

Easily Cleanable: The durable Vinyl upholstery on this model of the Kanewell Twin Adjustable Saddle Seat is waterproof and can easily be wiped down. Resistance to specific cleaning or disinfecting agents cannot be guaranteed but sample swatches for testing are available upon request.
Multiple Colour Options: All 3 heights of the Kanwewell Twin adjustable seat are available in Black vinyl. The Medium version is also available in Teal or Wine vinyl (while supplies last)
3 Height Options: The Kanewell Saddle Stools are available in three different heights, offering suitable options for virtually anyone. (see "Determining Your Saddle Height" in the User Tips Section)
Split Saddle Design: Split Saddle stools are designed to provide support in the right places. Weight is spread across and borne primarily by the sitting bones. A saddle seat at the correct height will also generally transfer some weight onto the insides of the thighs which further aids in spreading the weight over a larger surface area. Removing the crown of the saddle eliminates the risk of concentrating weight over a small and sensitive zone while the split design also encourages natural convective cooling airflow, resulting is a more enjoyable sitting experience than that offered by traditional chairs or one-piece saddle seats.
Adjustable Tilt: The forward tilt feature means that additional tilt or rotation of the pelvis can be achieved if there is a desire to enhance the upright posture. In addition, it aids in relieving lower pelvic pressure by lowering the front of the saddle seat.
Easy Rolling: Kanewell Saddle Stools are equipped with 60 mm casters (for hard floors). A simple push/pull action with the feet lets one manoeuvre around a work area with minimal effort.
Adjustable Width/Splay: The Split Saddle design of the Kanewell Saddle Stools also includes the ability to customize the split. Adjustments include the spread or width of the saddle (ie. reducing or increasing the space between the halves) and "splay" - adjusting the angle at which the seat halves interact. See "Seat Width/Splay Adjustment" under the Usage Tips section for details on how to accomplish these adjustments.
Quality Upholstery: Kanewell Vinyl Saddle Stools are upholstered with quality Vinyl for durability and ease of cleaning.
Weight Rating: Kanewell Twin Adjustable Saddle Stools are designed to safely support weights up to 300 lbs (136 kg).

Usage Tips

When considering a Saddle Stool it is wise to consider the entire workstation. The reason behind this is that an appropriately positioned saddle-style seat will raise you significantly higher than does a standard office chair. This means that other factors such as keyboard/mouse and monitor heights will need to be adjusted to bring them up to an appropriately ergonomic position. Failing to address these factors will usually result in you keeping the saddle positioned too low and losing most of the benefits which the saddle seat might otherwise offer OR potentially introducing other ergonomic issues while trying to reach a workspace that is positioned too low. If you have questions regarding solutions to these problems please feel free to call for assistance in addressing these concerns.
Selecting the appropriate model of the Kanewell Saddle Stool can be done by simply comparing your height to the recommended height ranges indicated for each model. If you happen to be at the upper height range for the Short or Medium models you may want to move up to the next height version. There is a significant enough overlapping range between the models to ensure that the next-taller version will still provide a range of adjustment both above and below your optimal setting. The suggested height ranges are based on individuals of average proportions. If you are aware that your leg-to-torso proportions are outside the average - i.e. unusually short or long legs, you will need to make allowance for that when selecting the appropriate height. In those cases consider whether to go "up" or "down" to a different model that would better match your leg length.
Seat Width and/or Splay Adjustment can be accomplished by loosening the handwheel located below the front of the saddle. It is recommended to release the locking mechanism by several turns prior to attempting to adjust the width or angle of the seat halves. Once the chosen width or splay angle is set you simply tighten the handwheel to re-engage the locking system.
Note: The locking mechanism is friction-based and may require that some effort be exerted when performing initial adjustments. Gently working the seat halves back and forth should loosen them up so adjustment can be made. Subsequent adjustments should be more easily accomplished.
When setting the height of the seat you want to have your thighs angled downwards at roughly 45° as this position provides optimal pelvic tilt for most individuals. This will also usually comfortably align the thighs with the angle of the seat halves, permitting them to rest naturally against the saddle and reducing the risk of pressure points on the inside of the thighs.
Be careful to not position the seat significantly lower than where the thighs are at the optimum 45° angle. Sitting in this manner changes the angle at which the pelvic bones contact the seat and concentrates your weight over a smaller zone along the upper ridge of the seat halves. This will for most people not only be uncomfortable but also pushes the lower spine into an unnatural C-curve. This posture exerts undue stress on the lower back and spine and greatly reduces the effectiveness of the Saddle Stool posture.
Moving about a workspace with the Kanewell Saddle Stool is much easier than moving a traditional office chair. Since the saddle posture provides your legs with a much wider range of motion, both feet can be employed to perform a push/pull action. Movement in any direction can be accomplished with a minimum of effort.
Saddle-style seating does require an adjustment period. Trying to perform marathon work sessions in the first days of use is discouraged. Rather, take the time to let your muscles and joints adapt to this new posture. Take breaks, use your old chair, stand up and stretch, and even walk around. Also, expect that over the first days and even weeks you may find that there is sensitivity. Adjust the seat to reduce pressure points or ridges, fine-tuning the seat position to meet your requirements. Of course, if you are an equestrian or cyclist you will almost certainly adapt very quickly since your body is already acclimated to this style of seat.
