STROMAN DESIGN ® | ( FORM X FUNCTION ) ® is an award-winning design studio that has been recognized internationally for its innovative approach to ergonomic design. This recognition is directly attributed to the studio’s unique approach to task seating which prioritizes a decompressed and fully supported recumbent seating posture over the typical upright, compressed and unsupported posture that most “ergonomic chairs” provide.


The studio’s unique design approach is reflected throughout its award-winning and patented ergonomic product introduction, the CHOTTO ® ( chair + ottoman ). The CHOTTO represents a uniquely human-centered ergonomic design approach that places the body in close proximity to a Neutral Body Posture. This is a posture that the body achieves naturally when it is free from all physical and gravitational forces ( NASA ).  This Neutral Body Posture, along with the unique geometry, headrest and dynamically flexible seating surface of the CHOTTO, effectively reverses compression throughout the cervical, thoracic and lumbar spine and eliminates muscle tension throughout the entire body. Unlike most “ergonomic” seating, the pivoting display and rotational task surface allow the body to remain in an enhanced state of musculoskeletal equilibrium while maintaining ergonomically ideal visual and physical accessibility to all digital tools & displays.

The primary objective of the CHOTTO is to minimize the physiological consequences of sitting by eliminating muscle tension, reversing skeletal compression and increasing blood circulation.  Simply stated, it is to achieve a healthy way of sitting.  In pursuit of this objective, the CHOTTO features a unique weight-displacing recumbent seating position and a multi-layer cushioning system that is comprised of an entirely flexible, pre-tensioned and cushioned seating surface. This cushioning system dynamically adapts to each occupant’s weight, shape and movement.  A rotationally and telescopically adjustable headrest can also be micro-adjusted within any number of its 98 unique positions to provide additional support for the head and neck.

An optional footrest elevates the legs while an immediately mobile, nested and freely rotating TASK TRAY ® provides a universal surface for eating, reading, writing, or digital interaction. This same tray can be repositioned within optional rear support brackets for use with the pivoting display interface / standup desk.  The pivoting display interface is based on design research that favors a human-centered display that literally revolves around the seated, tension-free and fully supported user.  If paired with a laptop, the PDI can also be used as a dual-screen interface in both the seated or standing position.  With the PDI in the default standup desk position, the CHOTTO simultaneously accommodates both a standing and seated user – all within a small 15 s.f. foot print.  Internally, the CHOTTO features enough space for large storage drawers that can be accessed from multiple angles and from both the seated and standing positions.

The CHOTTO’s enhanced functionality represents an exceptional example of the studio’s ( FORM X FUNCTION ) principle and helps fill the considerable void of a more considered approach to contemporary ergonomic design.

The CHOTTO was introduced in New York City at the 2016 ICFF and Northside Festival Innovation Expo.


The TASK TRAY ® is a rotationally adjustable and portable workstation that allows any work materials or devices to ergonomically transition with your body throughout any standing, sitting, reclining, recumbent or horizontal posture.

Like the award winning CHOTTO ( chair + ottoman ), the TASK TRAY is designed to enhance productivity by providing a variety of ergonomically desirable positions that prioritize each user’s physical and mental wellbeing.  The TASK TRAY excels as a portable workstation by granting anyone the freedom to determine wherewhen and most importantly, how they want to work. 

The TASK TRAY was introduced in New York City at the 2018 ICFF.

"With the introduction of the CHOTTO and the TASK TRAY,

it is my hope that anyone who must sit for extended

periods of time can now improve their quality of life

with extended comfort and productivity."
