The Twixt Active Seating Chair from Safco Products is intended to subtly encourage the user to actively engage their core muscles in movement through the course of the day. The Twixt is supported by a sturdy cast aluminum base equipped with a flexible ring that can compress as users lean away from the vertical, permitting the seat to tilt in any direction the user chooses. The large 15.5" diameter seat is well padded, with waterfall edges to reduce the potential of encountering pressure points from the seat edge. Users can also freely pivot a full 360° which makes it possible to turn away from a desk or workstation without the need of moving the seat. Seat height adjustment is accomplished with a gas spring cylinder, activated by a convenient release ring just below the Twixt seat. The gas spring also acts as a shock absorber to eliminate any jolts as one sits down. There are two height ranges available — the Desk-Height version which adjusts from 17" - 22" for shorter users or situations where lower seating is more suitable, and the Extended-Height model which adjusts from 22" to 31.75", making this model better suited for taller persons or for use at height adjustable sit-stand desks. The Twixt is available with either Mesh Fabric or Vinyl upholstery.

The natural flowing design of the WTRFL Perching Seat from ErgoVerse provides users with an angle-adjustable, contoured seating surface for both perching and leaning applications. The softly rounded front rises slightly to provide a "ledge" effect, keeping the user securely in position on the seat. 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. Formed channels facilitate cooling air flow. Height adjustment is accomplished with a gas spring that also serves as a shock absorber by providing a cushioning effect when the user sits down. The seat angle is adjustable from 0° to 14° allowing users to choose the most comfortable position. A convenient handle is integrated into the back of the seat for ease of movement about the workspace.

The SEET Leaning Stool from ErgoVerse is a lightweight portable leaning stool with an integrated handle and rollers for easy movement between work stations. The 16.5 pound SEET is suited more to short-term leaning or resting rather than as a long-term seat.

The tubular steel base supports a gas spring lift that offers seat height adjustment from 24.8" to over 33" and helps to minimize impact when the user sits down. The unique "cylinder roll" design is 12.75" wide, with a diameter of 3.5". The seat is formed from sturdy self-skinned non-absorbent polyurethane foam that is highly resistant to nicks or cuts. Deep cut ribbing on the roll provides a textured surface to facilitate airflow and helps to keep skin cool, dry and comfortable.

The new Stance Angle Chair from Health Postures reinterprets the industry leading concepts of their original Stance Chair. Users are once again able to enjoy the benefits of an office chair which effortlessly converts between Sitting, Kneeling and Assisted Standing. The Stance Angle Chair is the ideal seating solution for true Sit-Stand Workstations as it supplies an ergonomic "seating" solution for each style of working. Ahead of its time in addressing the requirements of the Sit-Stand working environment, the Stance has now come of age in a streamlined, more compact version—the Stance Angle.

The innovative design of the Stance Angle Chair makes it an ideal companion to sit-stand workstations, enabling users to seamlessly transition between Sitting, Kneeling, Assisted Standing (Leaning) and Standing throughout their workday. The freedom to effortlessly move between different postures will encourage regular movement, a key factor in achieving a healthy active-working environment. Unlike traditional seating which needs to be moved out of the way when moving from sitting to standing, the Stance Angle Chair simply moves with the user, offering a third position—"Kneeling"— which actively encourages correct spinal alignment and can aid in strengthening lower back muscles. When in the "Assisted Standing" mode the user is able to rest against the back of the Stance Angle while also reducing the load on the lower limbs and joints, further reducing overall user fatigue and contributing to a higher degree of alertness and greater productivity. The Stance Angle also features easily adjustable armrests which provide support to the arms in all three positions, reducing the risk of strain to the neck and shoulders even when standing.

The ease with which the Stance Angle Chair moves between working positions removes any obstacle to users who seek to actively shift between positions throughout the day. Users can be more engaged in their work as blood flow is increased through the increased movement, and leave work less fatigued.

The RISON Sit-Stand Stool (Classic) from Mey Chair Systems offers users the option of intermittently adopting a sitting position throughout the workday. Employing the RISON to bear the bulk of body weight permits the feet and legs to rest, reducing fatigue and potentially contributing to a more alert user.

The non-vertical, or leaning, stance effectively reduces the weight load on the joints of both the legs and the feet as the stool, rather than the legs and feet, becomes the load bearing support. The ability to position the seat in an elevated position also significantly reduces the effort required to return to a fully standing position. The shock absorbing effect of the easily adjusted gas cylinder provides additional comfort when the user sits down.

The non-pivoting seat offers an infinitely adjustable height range from 26" - 35.5" - suitable for users from about 5'2" up to 6'6". The polyurethane seat provides a firm yet cushioned seating surface with raised texture bumps. The detachable back support is also formed from the same foam as the seat. (Note: The back on the 11120 has a 2.5" deep curvature in the middle, is 14" wide, and has firm edges. Some users with broader frames may find the back on this model too narrow and deep for a comfortable fit. As an alternative they may wish to consider the EZSIT Comfort Elite Sit-Stand Stool , also from Mey Chair Systems, which offers a broader back (and seat) better suited to users of larger build.)

While the seat does offer the option of tilting it to accommodate a "leaning" position rather than the seated position the fact that the back support on this model is rigidly mounted to the tilting mechanism means that it is really only suitable for upright sitting (ie. when tilted the back follows the movement of the seat and prevents the adoption of a proper upright stance. Users wishing to use this seat as a "leaning" seat should consider the current model of the RISON which now incorporates independent back angle adjustment into the seat mechanism. The current seat-only version of the RISON is also available in two height ranges to accommodate the varying needs of users.

The heavy-duty textured black tubular steel base on the RISON Sit-Stand Leaning Stool is designed for industrial settings but functions well in many offices, providing strength and stability. Strong nylon glides engage the floor to ensure firm positioning of the seat and the incorporated rollers permit the chair to be easily moved between workstations. The unique design of the base maximizes stability while greatly reducing the risk of tripping for passersby.

The UP Stool from Interstuhl features a convex non-slip bottom that encourages users to rock and shift in all directions, actively engaging a wide range of core muscles and assisting in maintaining lower torso joint mobility. Designed for short term sitting, the UP Stool is a lightweight, portable, and height adjustable "action seat". Easily moved between locations, the UP Stool is a perfect office solution for quick meetings, short conversations or brainstorming sessions, or simply for taking short sitting breaks at a sit-stand desk.

With a quick tug of the release strap—which conveniently doubles as a carrying grip—users can set the stool height to any position between 17.7" and 24.8" for optimum comfort. The wide range of adjustment means that it can meet the needs of virtually any situation or height of user. The UP Stool has a foam insert which offers a minimal degree of padding ideal for short term usage, and a concave seatpan which is surprisingly accommodating for a wide range of body types.

The Mobis II Seat is part of the next generation of lean-to (or -into) stools. Based on the original Mobis Seat it features a thicker seat cushion than the Mobis I, making it more suitable for users who intend to "sit" rather than "lean" throughout the day. Its unique design permits 6º of pivoting movement in all directions through a secure pivot point at the base. Rather than simply reducing the workload on the legs by taking the weight of the upper body (which traditional lean-to stools accomplish), this pivoting capability allows the Mobis to move with users as they perform tasks. This light-weight, elegant, grab-and-go version of the Locus Seat supports the body in a relaxed, upright posture. The Mobis II Seat has a range suitable for people from 4'11" to 6'8" tall. Dual lift controls let it be easily adjusted for work surfaces of varying heights. The small footprint of the Mobis II also makes it ideal for anyone creating a workstation that includes sitting or standing. By providing an in-between seating option for short-term tasks, the transition to a standing position becomes almost effortless. The Mobis II offers enough support to keep fatigue at bay, while still allowing the user to rotate a full 360º, to turn from side to side, and to flex forward, backward and laterally. The Mobis II is ideal for raised conference room table applications. Offering many real ergonomic benefits and improved comfort, the Mobis II is also a uniquely styled seating option that will make a positive statement about the workplace, as well as the occupant of the workstation.

The Mobis II Seats feature a Black base with Silver gas lift.

Mobis users might consider adding the Focal Foot Bar, to their workstation. The Focal Foot Bar is designed for users who would like to brace their feet against a sturdy, slip-free support when working at a sit-stand workstation, or who would like to prop one foot up from time to time when standing to alleviate strain on the lower back.

Caution: Focal Upright recommends against using the Mobis Seat with a standard foot rest, especially those with non-locking foot platforms.

The LOTAH Perching Comfort Saddle Seat from ErgoVerse is well-suited to users who need to work as close as possible to the work surface of an elevated workstation, particularly those built on top of base cabinets or shelves. The LOTAH features a large plush saddle designed to be straddled, rather than leaned against. While keeping the torso in an ergonomically desirable upright orientation, the straddle posture positions the heels behind the bend of the knees, rather than extended forward of the knees as they would be on a leaning stool. (See the Tulean Leaning Stool, also by ErgoVerse, for an illustration of this latter position.) This posture allows the user to move in much closer to flat-fronted work surfaces than might otherwise be possible. As a result, the LOTAH Perching Comfort Saddle Seat helps to reduce the risk of overreach injuries to the muscles of the shoulders and back, and the risk of injury to the muscles of the sides and mid-section caused by sitting sideways along the base of the workstation and twisting at the waist to get close enough to its surface. The LOTAH Perching Comfort Saddle Seat also helps to reduce the load borne by the feet and legs for those who work at elevated workstations by transferring the majority of the user's weight to the seat. As a result the user experiences less overall fatigue and a greater ability to maintain focus and concentration.

Built on a heavy tubular steel base with a gas spring that enables a height adjustment range of 24.8" to 31.5", and with a seat that has 15° of tilt range and 3" of cushioning, the LOTAH offers individualized comfort and long-term durability.

The FYLDST Foldable Leaning Stool from ErgoVerse offers users the opportunity to sit or lean while working. In addition to reducing the weight load and stress on the joints of the legs, this posture also lets users quickly move back to a fully standing position with minimal effort.

Designed with portability in mind, at only 14.3 lbs the FYLDST enables users to easily move their chair with them between locations or job sites. This stool offers an extended range of seat height adjustment from 21.25" to 35.4" which will accommodate virtually every user and is rated to support 264 lbs. Heavy rectangular tube steel construction, simple folding hinges, and handwheel adjustment of seat height mean this chair will last through years of heavy use. The Formed Polyurethane fixed seat angles slightly down at 10°, providing a comfortable resting place throughout the day. The textured surface of the seat facilitates airflow and makes the seat feel softer, improving comfort.

The simple design of this model results in a rigid seating position, with the only cushioning being that of the reasonably firm formed-polyurethane seat. Users looking for more cushioning or not requiring portability may wish to consider one of the numerous other models from ErgoVerse, with options of softer padding in the seats or gas spring cylinders for shock absorbance.

The Stance Move chair's unique design enables users to shift between multiple sitting positions throughout the day. Designed with Sit-Stand workstations in mind, it provides three distinct seating positions - Forward Sloped Sitting, Kneeling, and Assisted Standing. Each of these options moves the user away from the static closed-core position that traditional seating creates. The backless design encourages the users to maintain an upright stance by actively supporting their pelvis in a forward tilt which improves back posture. This position encourages strengthening of core muscles as the user is required to maintain torso balance at all three settings. By removing the seat back the risk of slouching or rounding of the lower back is significantly reduced, which in turn can reduce the risk and occurrence of lower back pain which is often related to traditional seating.

With a simple move of a lever the Stance Move converts into a kneeling stance, a well-known posture which positively encourages proper spine positioning by tilting the pelvis even further forward than the Forward Tilt mode. The Kneeling position which has been used in many workplaces throughout the years. The thick kneeling cushions support the knees and spread pressure to enable users to comfortably maintain this position for extended periods.

For users who prefer a more upright position or who wish to fully vary their seating throughout the day, the Assisted Standing position is the third position offered. Many users of Sit-Stand workstations have found that standing for extended periods can be exhausting as the standing position requires muscles to be held in constant tension in order to be able to maintain that static position. As these users have discovered, muscle fatigue can occur even in a standing position. As well, the lower legs and feet begin to tire over the course of the day, resulting in an overall loss of energy. This loss of energy will translate into a more "slumped" posture as the body tires. The slumped position then further accentuates the fatigue as it puts strain on muscles and tendons which are already tired from extended use. The Assisted Standing position is intended to address this as it takes a percentage of the weight load and transfers it to the chair rather than placing it directly over the feet and legs. The enables the muscles of the legs and lower back to relax, thereby reducing the fatigue related to continuous tension. The release of muscle tension in the lower legs will also permit better bloodflow in the legs, something which is a known concern related to extended static standing.

The Stance Move is designed for users up to 5'9". Taller users will benefit from the Stance Move EXT 5050 which comes with a seat extension.
