Modular construction
Good products evolve. Components can therefore be maintained, replaced or upgraded as new technologies become available.
The chair evolves with new insights while retaining its high-quality foundations.
Designed for circular use
Built for years of use.
Every Sit-i chair starts with one principle: quality. It shapes the construction, the choice of materials and the way each chair is assembled.
Sit-i Return
You can apply for Sit-i Return from twelve months after first delivery. The chair’s age continues to run from that first delivery, including when ownership changes.
Shipping and transport are at your own expense. You can drop the chair off at a Sit-i Professionals location without a drop-off fee. Contact us beforehand to agree the drop-off location.
Contact us with the details of your Sit-i chair.
We review the model, technical condition and options within Sit-i Return.
You receive a personal proposal based on your chair and current demand.
If the chair is offered again as Sit-i Certified, it first undergoes the technical inspection.

Every material contributes to the quality of the finished product. Sit-i Athlete · Pro and Opus are upholstered in high-quality rPET made from recycled PET bottles.
For other models, we choose materials suited to their application, use and intended service life.
Materials, construction and finish come together in a chair that feels comfortable, withstands intensive use and retains its quality for years.

The indicative maximum percentages are calculated on the original purchase amount for the Sit-i chair shown on the purchase invoice, including VAT and excluding shipping costs. The chair’s age is counted from its first delivery date.
The percentages are not a guaranteed buyback payment. Kinamics determines a personal proposal after technical assessment.

Sit-i Certified
Where necessary, components are replaced, software is updated and sensors are checked. Certification provides a clear picture of the technical condition.
Kinamics carries out the technical inspection for Sit-i Certified. Upholstery and Penthapod® condition are classified using the criteria below. The chair also undergoes technical inspection before being made available again.
| Class | Condition and criteria |

| ★★★★☆ | Very good No signs of use on the upholstery; superficial scratches on the Penthapod®. |
| ★★★☆☆ | Good Signs of use on the upholstery and scratches on the Penthapod®. |
| ★★☆☆☆ | Heavily used Damage to the upholstery and scratches on the Penthapod®. |
| ★☆☆☆☆ | Lowest Return class Individual technical assessment and a take-back proposal, including when renewed use as Sit-i Certified is not possible. |
Take-back and offering a chair again as Sit-i Certified are assessed separately.
