The Festool SK-CT/SYS Seat Cushion (578730) transforms compatible Festool CT dust extractors, Systainer storage cases, and the SYS-RB roll board cart into a comfortable, padded seating or kneeling workstation. Built from cushioning, cold-insulating Expanded Polypropylene (EPP), this portable seat cushion reduces knee and back strain during low-height tasks, floor-level assembly, or jobsite breaks.

Designed for quick jobsite integration, the seat cushion attaches directly to Festool dust extractors equipped with a Systainer interface or any standard T-LOC Systainer case. It locks securely using the integrated T-LOC latch mechanism, allowing the entire setup to be transported together without removing components. The water-resistant, easy-to-clean EPP material withstands daily jobsite wear while insulating against cold concrete floors.

For added organization, the SK-CT/SYS features an integrated storage tray in the seat surface to keep screws, fasteners, and small parts within reach. A padded 1 in. (25 mm) textile carry strap provides comfortable handling during transport and conveniently retracts flush when seated. When mounted to the SYS-RB roll board cart, it creates a mobile rolling seat that allows smooth movement across work areas during low-level tasks.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery. We use USPS, which typically takes 2-8 days for delivery, depending on your location, for smaller items and UPS Ground for all other ground shipments under 150 pounds.

• Returns: We accept returns and exchanges for a fee up to 30 days in unopened, new, and unused condition in the original packaging. Exceptions apply.

If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.
