Upgrade your bankside experience with the Matrix S25 Pro Accessory Chair. This isn’t just a place to sit; it’s a high-performance fishing station designed for the angler who demands the comfort of a chair but the technical capabilities of a seatbox. The “Pro” version has been significantly upgraded, now featuring four fully adjustable 25mm extendable legs that allow you to attach side trays, feeder arms, and pole supports with ease.
At Gerry’s Fishing, we highly recommend the S25 Pro for feeder and float enthusiasts. The combination of a lightweight frame and a deluxe, oversized padded cushion means you can hike to distant pegs without fatigue and fish in total luxury once you arrive. Whether you are fishing a steep river bank or a flat commercial deck, the four-way leg adjustment ensures a perfectly level seat every time.
25mm Accessory System: The four 25mm round legs are compatible with a huge range of Matrix and universal seatbox accessories, turning your chair into a complete fishing station.
Upgraded Leg Mechanism: Four fully adjustable, extendable legs allow for precision leveling on any terrain, from concrete towpaths to muddy slopes.
Maximum Support: Features a high backrest and a deluxe, oversized padded seat cushion designed to provide lumbar support during long match or pleasure sessions.
Ultimate Portability: Despite its robust build, the chair is constructed from lightweight materials (6.3kg) and folds completely flat for easy transport.
Smart Storage: Comes with a detachable shoulder strap, with a dedicated storage area under the seat to keep it out of the mud while you fish.

River Feeder Fishing: The extendable legs are perfect for setting up on uneven, rocky, or steep river banks where a standard chair would be unstable.
Canal Match Fishing: Use it on narrow towpaths where you need a compact footprint but still want to attach a side tray and a pole rest.
Long-Stay Pleasure Sessions: If you’re spending 8+ hours on the bank, the “Deluxe” padding provides significantly better comfort than a traditional match seatbox.
Pro Tip from the Gerry’s Team
Because this chair uses 25mm legs, it’s the perfect companion for a Matrix 3D-R Feeder Arm. By attaching your arm directly to the front leg of the chair, you create an incredibly stable rod rest that won’t wobble when you move in your seat—essential for spotting those tiny “wrap-around” feeder bites!
Will my old seatbox accessories fit these legs?
The S25 Pro uses standard 25mm round legs. It will fit all Matrix 3D-R accessories and most other brands’ 25mm-compatible attachments.
How high does the seat sit off the ground?
With the legs fully retracted, it offers a standard chair height. However, the extendable legs allow you to raise the chair significantly, which is a great help for taller anglers or for sitting above tall grass and reeds.
Is the shoulder strap comfortable for long walks?
Yes, the strap is well-padded and balanced. Because the chair folds so flat (only 18cm deep), it sits comfortably against your side without banging against your legs while you walk.
