What Sittab Inc does

Sittab Stol AB, operating commercially as Sittab Inc in North America, is a Swedish designer and manufacturer of ergonomic seating accessories for professional vehicle operators, founded in 1991 and headquartered in Gustafs, Sweden. The company produces armrests, seat turntables, headrests, vibration isolators, suspensions, pedestals, slide rails, sledges, tilt units, and footrests, organized across 12 product categories with multiple model variants (eight armrest lines, nine turntable models, three isolator configurations, and so on). Products are engineered for harsh-duty applications in forestry, construction, mining, material handling, agriculture, marine, transport, and office/workstation environments, and many are developed in direct co-engineering collaboration with OEM customer development departments.

Sittab generates revenue through B2B hardware sales to OEM vehicle manufacturers (John Deere Forest, Komatsu Forest, Volvo CE, Caterpillar, Epiroc, Sandvik, Kalmar, Konecranes, Jungheinrich, Claas) and to tier-1 seat assemblers (KAB Seating, Grammer AG, Be-Ge Seating, Isringhausen, Kinnarps), using a quote-based pricing model without public list pricing. Go-to-market combines direct OEM field sales in Europe (50-70 travel days per year per rep) and the US, with regional sales/marketing offices in the USA (Hudson, WI, established 2011), China (Dongguan), and Finland (Iisalmi, acquired via HP Rotacenter in December 2022), plus a distributor network spanning 32 locations in 18 countries including Australia, Canada, and Japan. Trade-show presence at AGRITECHNICA, ConExpo, Swedish Forestry Expo, and InnoTrans supports lead generation. Total group turnover is approximately SEK 170 million across roughly 65 employees in Sweden, USA, China, and India, serving 350+ customers in over 30 countries.

Since 2013 Sittab has operated as a subsidiary of the Addtech Group under its Vehicle Solutions business unit, with Addtech providing financial backing and an explicit acquisition mandate. The company holds ISO 9001 and ISO 14001 certifications, has a patent-pending Comfort headrest design, and reports revenue tied to heavy-duty specifications such as a 25,000-hour suspension lifetime and 200kg maximum driver weight on its flagship Robust suspension line. Leadership transitioned in December 2021 when Patrik Assmundson was appointed Managing Director, succeeding Anders Claesson, who moved to an Addtech group-level Vehicle Solutions role.
