Who it suits
Is it right for you?
Great for
- Match anglers building a proper modular setup. The six-leg frame, tidy storage and accessory threads give you a solid base for floats, feeders, bait tools and extra attachments.
- Coarse anglers who fish uneven or soft banks. The levelling aid, telescopic inserts and swivel mud feet help you create a more stable fishing platform.
Maybe skip if
- Mobile anglers who travel very light. At 18.5kg before you add bait, rods and luggage, it’s more suited to organised sessions than quick roving.
- Anglers wanting maximum storage straight out of the box. The included drawers are useful, but a tackle-heavy approach may soon have you looking at extra units.

- Supplied with one deep drawer, two single trays and one transport lid.

Quick verdict
Verdict
The Matrix S36 Superbox is a cracking starting point for the coarse angler who wants a proper modular seatbox without immediately filling the garage with extra units. It’s stable, sensibly laid out and ready for a broad mix of match and pleasure fishing.
At 18.5kg it’s not featherweight, but that heft brings a planted feel on the bank. The built-in spirit level, big swivel mud feet and sliding footplate all add up to a box that’s easy to get comfortable on and quick to set up when the bite-time starts.

The aluminium frame, padded seat, anti-warp footplate and substantial leg hardware point to a well-equipped, properly made platform.
Six 36mm legs, telescopic inserts, a spirit level and swivel mud feet give it a stable, adaptable stance on the bank.
Tidy storage and a level, comfortable platform help you react faster and fish more efficiently when the swim gets busy.
The sliding footplate, carry strap and supplied drawer combination are practical, although the 18.5kg weight makes moving it a job.
You get a strong modular base plus four useful storage components, making it a good starting point for a serious coarse setup.

The full rundown
Everything you'll want to know about the Matrix S36 Superbox
A proper seatbox can transform a coarse session. You’re not perched on a wobbly chair, your rigs aren’t rattling around in three old bait tubs, and the rods are off while you’re still hunting for the disgorger. The Matrix S36 Superbox is aimed squarely at that organised, match-style way of fishing.
It’s a fairly serious bit of kit, mind. At 18.5kg, this isn’t the box you casually sling over one shoulder for a quick wander round the canal. It’s a substantial platform for anglers who want stability, useful storage and the option to build a more complete setup over time.
The frame uses lightweight aluminium, with six chunky 36mm legs and 25mm telescopic inserts. That gives the box a strong, planted stance without making the whole thing feel like a lump of scaffolding. You can get the legs dialled in for sloping banks, awkward pegs and those swims where the ground seems to have been designed by a committee of moles.
Levelling is helped by the built-in spirit level in the padded seat. It’s a small touch, but a dead handy one. Rather than eyeballing the box and hoping for the best, you’ve got a quick visual check before settling in. That matters when you’re fishing a long pole, feeding accurately or just trying to keep your knees and back happy through a full match.
Underneath, the large-diameter swivel mud feet are designed to spread the load and cope better with softer ground. They won’t turn a quagmire into a car park, obviously, but they’re much more reassuring than tiny feet sinking into the peg every time you shift your weight or reach for a feeder.
The footplate is another important part of the package. It has an anti-warp design, so it’s built to stay useful as a solid platform rather than becoming a bendy nuisance. Even better, it slides under the frame for transport. That keeps the box more compact when you’re packing up, and means one less loose component to leave beside the peg after a long day.
Storage-wise, Matrix has gone for a sensible starter combination. There’s one deep drawer unit for bulkier bits and two single tray units for the small stuff. Think hooks, shot, swivels, feeders, floats and spare rigs. You can keep the frequently used gear where your hands naturally fall, instead of rummaging through a cavernous holdall while a bite is developing.
All six 36mm legs have accessory threads in their tops. That’s a big plus if you like to tailor a box around your fishing. Keep the setup clean for a short canal match, then add the bits you need for pole work, feeder fishing or longer days on a commercial. It gives the S36 Superbox some proper legs — literally and in terms of future flexibility.
The removable padded carry strap is useful when the box is folded and ready to move, while the padded seat makes the whole platform more comfortable for a long session. Available in black, lime and blue, it’s got a bit of visual personality too. Overall, this is a well-equipped, high-value seatbox for anglers who want a stable base now and room to grow later, provided you’re happy carrying the weight.

Our take
A well-specced platform for busy coarse sessions
The big draw here is the combination of a lightweight aluminium frame and a useful starter storage package. You get a deep drawer for bulkier bits, two single trays for terminal tackle and a transport lid to keep everything together.
It’s a high-value option for match anglers who want room to organise floats, shot, feeders, hooks and rigs around the session. The six 36mm legs also give you plenty of scope for accessories, so the box can evolve as your fishing does.
What you’re buying
A stable, modular base with useful storage
The S36 Superbox combines a lightweight aluminium frame with six 36mm legs, 25mm telescopic inserts and a padded seat. That’s a strong recipe for getting properly settled on the bank, whether you’re fishing a pole, feeder or a bit of both.
The supplied storage is nicely practical rather than overcomplicated: one deep drawer, two single trays and a transport lid. The deep unit handles bulkier tackle, while the trays are bob on for hooks, shot, floats, feeders and ready-made rigs.
Worth knowing. The footplate slides under the frame for transport, and all six leg tops have accessory threads. So the box packs away neatly but still leaves plenty of scope for adding compatible extras later.
Find your fit
Best for organised coarse anglers
This is aimed at the angler who wants more than a basic seat and a couple of tackle boxes. Match anglers, regular commercial-fishery visitors and anyone who likes a tidy, repeatable setup will get the most from it.
The built-in spirit level, telescopic legs and swivel mud feet are especially useful on uneven pegs. Get the platform level, keep the tackle in reach and you can focus on feeding, presentation and spotting that little lift on the float.
Worth knowing. At 18.5kg, think ‘proper seatbox’ rather than ‘lightweight roving chair’. It’s a cracking choice for planned sessions, but a bit much if you’re walking miles with minimal kit.
Before you buy
The bits anglers usually want to know
The storage supplied should cover a broad range of coarse fishing, but very tackle-heavy anglers may eventually want extra trays or accessories. That’s where the modular six-leg layout earns its keep.
The colour choice is black, lime or blue, so you can keep things understated or add a cheeky splash of colour to the peg. The removable padded strap also makes the folded box easier to shift between the car and the swim.
Worth knowing. If your fishing involves lots of carrying, plan the rest of your load carefully. The box itself is 18.5kg before you add bait, rods, landing-net handles and all the other bank-side gubbins.
